Cortisol Explained: Is the Stress Hormone Actually Bad for You?

Vitamins, Minerals & Supplements

Have you been told cortisol is the ‘stress hormone’ to avoid? It’s often portrayed as the culprit behind poor sleep, weight gain, and burnout.

In reality, cortisol is an essential hormone that helps us wake up in the morning, access energy when needed, and respond to everyday demands.

However, when the stress response remains activated for prolonged periods, cortisol can become elevated or dysregulated. That’s when symptoms may start to appear.

With so much discussion online about ‘high cortisol’, ‘cortisol belly’ and ways to lower stress, it’s easy to feel confused about what cortisol actually does. Keep reading to learn more about cortisol, why it may become disrupted, and what can help support balance.

What Is Cortisol and Why Do We Need It?

Despite the popularity of ‘cortisol detox’ advice, cortisol is actually an essential hormone involved in many normal physiological processes, including:

Waking up and feeling alert
Accessing energy when needed
Maintaining healthy blood pressure
Supporting our immune system and how it responds
Helping to regulate inflammation

Cortisol also follows a predictable daily pattern. It typically rises in the morning to support alertness, also known as the cortisol awakening response, then gradually declines toward evening to support rest and recovery .

In short bursts, cortisol is protective. It helps you respond to challenges appropriately. Problems tend to arise when activation becomes prolonged.

Common Signs of Balanced vs High Cortisol Levels

Balanced Cortisol Symptoms
High Cortisol Symptoms

Wake up feeling refreshed
Wake up feeling tired or wired

Energy gradually declines toward evening
Energy crashes during the day

Able to cope with everyday stress
Feeling overwhelmed by minor stressors

Stable mood and focus
Irritability, anxiety or brain fog

Regular appetite
Increased cravings, especially for sugar

Sleepiness at night
Difficulty falling or staying asleep

These patterns do not diagnose high cortisol on their own, but they may suggest that the body’s stress response has been activated for longer than intended. To understand why this happens, it is helpful for us to look at how the body normally responds to stress.

What Causes High Cortisol?

Your body is built to react quickly to immediate threats. You might be familiar with the ‘fight-or-flight’ response, the body’s acute stress reaction.

During acute stress, the brain activates the hypothalamic–pituitary–adrenal (HPA) axis, leading to increased cortisol release.

You may experience your heart rate accelerating, faster breathing, and muscles preparing for action. Your liver also releases glucose (sugar) to provide quick energy, helping your body respond to the perceived threat.

In the short term, this can be useful.

The challenge is that modern stressors, such as deadlines, traffic, work pressure, disrupted sleep, late-night screen exposure, irregular meals, high caffeine intake, and constant notifications, may not be life-threatening, but they still activate the same stress pathways.

Over time, this sustained activation, often referred to as chronic stress, can affect how the stress system functions and disrupt cortisol’s natural daily rhythm (3). Instead of rising in the morning and gradually declining toward evening, the pattern may become less predictable.

Cortisol Belly and Cortisol Face: Are They Real?

In the UK, chronic stress is increasingly common. One in three adults reported experiencing high or extreme stress ‘often’ or ‘always’ last year.

Stress hormones help release glucose into the bloodstream to provide quick energy when it’s needed. Unlike our ancestors, though, we rarely run away from the ‘threat’. Over time, and alongside other risk factors, this pattern may contribute to less stable blood sugar control in some individuals.

So, does cortisol cause belly fat? Not exactly. The term ‘cortisol belly’ is often used online to describe weight gain around the stomach that people associate with chronic stress. Cortisol itself isn’t a direct trigger for abdominal fat gain. But chronic stress can influence appetite, cravings, sleep quality and blood sugar control. Over the longer term, that combination may make visceral fat gain more likely in some people, which is why the idea of ‘cortisol belly’ has taken off online.

What about ‘cortisol face’? This term is often used on social media to describe a puffier-looking face. There’s currently limited research supporting it as a defined medical condition. That said, stress can influence fluid balance and inflammatory pathways, which may contribute to temporary puffiness in some individuals. More pronounced facial swelling, sometimes called ‘moon face’, is typically linked to medical conditions involving excessive cortisol production (such as Cushing’s syndrome), rather than everyday stress.

How to Reduce Cortisol Naturally

If you’re wondering how to lower cortisol naturally, the goal isn’t to eliminate cortisol, but to support the systems that regulate the body’s stress response.

Here are a few tips that can help you manage stress more effectively:

1. Reduce Stressors

Sometimes emotional stressors are unavoidable. However, other stressors such as poor sleep, under-eating, excessive caffeine intake, and large swings in blood sugar can also activate the stress response. Keeping blood sugar more stable can help reduce unnecessary physical stress on the body.

To support this, aim for regular, balanced meals that include a source of protein, fibre and healthy fats. These can help you maintain steadier energy levels and reduce unnecessary stress signalling.

2. Support Circadian Rhythm

Cortisol follows a circadian rhythm. Disruption to sleep timing, late-night light exposure and irregular schedules can affect this pattern.

Morning daylight exposure, consistent sleep timing and limiting screen time late in the evening may help support normal cortisol rhythm.

3. Mindfulness

Mindfulness practices can help support relaxation, helping your body come out of ‘fight-or-flight’ and back into a calmer ‘rest-and-digest’ mode. This does not necessarily mean formal meditation. Instead, it can be anything that helps you to switch off.

Activities such as walking in nature, attending a yoga class, chatting to a friend, journalling, reading, or simply taking time away from screens can all support stress management

4. Gut–Brain Axis

Emerging research suggests the gut microbiome may influence how the body responds to stress through the gut-brain axis. The gut and brain are in constant two-way communication, and this may influence how the body regulates stress.

Supporting gut health through fibre-rich foods, plant diversity and fermented foods may contribute to healthier cortisol levels over time.

5. Nutrients That Support the Stress Response

Certain nutrients play an important role in supporting the body’s response to stress:

Nutrient
What it supports
Food sources

Vitamin C
Supports psychological function and the immune system.
Citrus, berries, kiwi, peppers, broccoli

Magnesium

Contributes to the reduction of tiredness and fatigue and normal nervous system function.

Nuts, seeds, leafy greens, legumes, whole grains, dark chocolate

B vitamins
Support energy-yielding metabolism and normal psychological function.
Leafy greens, legumes, eggs, meat, fortified foods

Omega-3 fatty acids
Contributes to the maintenance of normal brain function.
Oily fish, algae oil, chia and flaxseeds, walnuts

6. Adaptogens

One of the most well-known is Ashwagandha (Withania somnifera). While research is ongoing into how its active compounds, such as withanolides, interact with the body, it has a long history of traditional use for supporting relaxation and emotional balance.

Ashwagandha’s main active ingredients are known as withanolides, alongside other naturally occurring compounds such as alkaloids and saponins. These compounds are believed to contribute to its effects on the body’s stress response. Ashwagandha can offer an additional layer of support for the body’s stress response, particularly through its effects on the HPA axis.

Final Thoughts

Cortisol is often misunderstood. It plays an essential role in helping the body respond to everyday demands, and the key is to support the systems that regulate the stress response, including sleep, nutrition, gut health and stress management.

Zinc Picolinate vs Other Forms of Zinc: Benefits, Absorption and Uses

Vitamins, Minerals & Supplements

Are you baffled by the number of zinc products on the market? There’s zinc picolinate, zinc gluconate, zinc citrate, zinc oxide – each one is different but it’s not always clear why. To solve this confusion, we’re diving into the science behind zinc picolinate and other forms of zinc to explore the benefits, absorption, and uses of this powerful mineral.

What does zinc do?

Zinc is an essential co-factor for hundreds of enzymes linked to:

Protein, fat, and carbohydrate digestion
Brain health and mental wellbeing
Fertility and reproduction
Metabolism of vitamin A
Bone, hair, skin, and nail health
Normal testosterone levels
Healthy vision
Immune system activity
Cell division and DNA formation
Antioxidant protection

Even though it’s needed for so many activities, your body only contains between 1.5-2.5g of zinc. The amount may be small but its actions are powerful.

What is zinc picolinate?

To be taken as a supplement, zinc needs to be combined with a carrier molecule, which affects the absorption and bioavailability of the mineral.

Zinc picolinate is zinc bound to picolinic acid, a natural by-product of the amino acid tryptophan. This organic carrier molecule makes zinc picolinate easier to absorb and more usable than other forms of zinc.

What are the benefits of zinc picolinate?

Zinc picolinate is better absorbed and utilised than other forms of zinc. Some of the common reasons why people choose zinc picolinate are for immune support, skin health, healthy vision, and to enhance fertility.

Zinc picolinate for immune support

Zinc influences immune cell development, a balanced immune response to infection, and antioxidant protection against cell damage.

Zinc for skin, hair, and nail health

Collagen, the structural protein in hair, skin, and nails, depends on healthy amounts of zinc. Zinc is often used to help manage acne and oily skin as it helps regulate sebum production from oil glands.

Zinc for healthy vision

The delicate tissues in the eyes are rich in zinc. It acts as an antioxidant to protect against the harmful effects of UV light.

Zinc for fertility

Zinc is essential for male and female fertility. It supports every part of the reproductive process, from sperm formation and motility to egg development, fertilization, and a healthy pregnancy.

Zinc picolinate vs zinc citrate and gluconate

Let’s compare zinc picolinate with other forms of zinc:

How to choose the best form of zinc supplement

The best form of zinc for absorption and bioavailability is zinc picolinate. It’s also well tolerated and gentle on the stomach compared to zinc gluconate or oxide.

When choosing a zinc picolinate supplement, look for a product that clearly states how much usable zinc is in each capsule (not just the total weight of the mineral and its carrier molecule) and make sure it’s free from unnecessary binders, fillers, and additives.

Zinc picolinate dosage and safety

The right dosage of zinc varies from person to person. It depends on things like how much your body needs, how much you already get from food, and how well your body absorbs nutrients. An optimal dose for a zinc picolinate supplement is 25mg.

Beyond Fuel: Understanding the Real-Life Challenges That Affect Athletic Performance

Sports Nutrition & Performance

Most athletes blame their performance shortfalls on training. They log more miles, hit harder in the gym, push through longer sets. But the variables that actually separate elite competitors from everyone else correspond to nutrition timing, sleep quality, hydration strategy, mental resilience, and how your body adapts to environmental pressure. These are real-life decisions you need to make daily.

The pressure to perform is real, whether you’re competing internationally, taking up sport for fun, or managing a rigorous corporate schedule. But getting started with the right support is itself a struggle. When someone reaches for a supplement to optimize their lifestyle, they’re immediately faced with questions:

Is this substance banned in my sport?

Does it contain anything on the prohibited list?

Can I even bring this across state lines when I travel to competitions?

Before any lifestyle decision, athletes encounter real friction. Before any choice, they need answers.

In this article, our team breaks down five non-training factors that derail performance. More importantly, we give you concrete steps to address each one.

#1 Nutrition: More Than Calories

What you eat and when you eat it directly influences your output on game day or race day. Calorie quantity matters. So does the source. A thousand calories from processed carbs behave differently than a thousand from whole grains and protein.

But nutrition isn’t one-size-fits-all. Female athletes, in particular, face a distinct set of needs. Iron absorption drops during certain menstrual phases, so meal timing shifts. Energy availability affects hormonal function. A “balanced diet” gets marketed entirely differently to men and women, leading to many women athletes not focusing on energy uptake.

Micronutrient gaps are easy to miss until they accumulate. Vitamin D sits directly in musculoskeletal health and testosterone production. Vitamins C and E manage oxidative stress and inflammatory pathways, which are your body’s response to training stress. When food alone can’t provide you with all the micronutrients you need, a targeted supplement can be considered.

If you do choose a multivitamin, be rigorous about three things:

The actual dosage of each nutrient

Whether the ingredients come from quality sources

Third-party verification that the formula stays true to the label

A high-dosage supplement marketed to athletes doesn’t help if it also contains hidden additives. Formulation integrity determines absorption. Even the most precise nutrition plan collapses without fluid management.

#2 Hydration: Replenish Electrolytes

Hydration is more nuanced as it involves science and personal trial-and-error. Drinking “eight glasses a day” tells you nothing about actual fluid balance. What matters is electrolyte replacement for the sodium and potassium your body loses through sweat. Electrolyte sports drinks replenish what water alone cannot, and some formulas add additional micronutrients to speed recovery.

But not all electrolyte drinks are equal. Sugar content varies wildly. Sodium concentration matters more, especially for endurance athletes. Distance runners and cyclists need higher sodium loads to maintain proper fluid balance during extended efforts. A cyclist finishing a four-hour ride has different electrolyte needs than a sprinter finishing a 200-meter race. The drink that works for one may not be suitable for the other. Your electrolyte strategy should evolve as your training demands vary.

#3 Recovery: Rest Matters as Much as Training

Athletes with personal bests and medals often have those results at the cost of sleep, mood stability, and basic physical maintenance. Training hard and recovery are not opposing aspects in an athlete’s life. Recovery is what supports the training to turn into performance.

The data on this is clear. A 2025 review in the Journal of Sports and Rehabilitation Sciences studied how athletes maintain mental resilience through recovery, particularly during competitive stress. It found that athletes don’t get enough sleep, and the quality of what sleep they get often suffers. Travel schedules break sleep patterns. Demanding training sessions heighten competition anxiety. When sleep drops, reaction times slow and decision-making becomes sluggish. Injury risk climbs, and illness becomes more likely.

Recovery has two layers: what your muscles need and what your brain needs. Both matter equally.

Sleep quality starts with routine. But it also requires acknowledging what sleep disrupts it. Is it jet lag from travel? Is it pre-competition anxiety that keeps you awake at 2 a.m.? Is it a genuine sleep disorder, or just a schedule that leaves no room for sleep? Your answer to this self-exploration determines the solution. Sleep logs during travel blocks reveal patterns you may miss otherwise.

#4 Mental Focus: The Overlooked Performance Driver

Athletes obsess over rep counts, calorie tracking, and the numbers on a scale. Mental skill training gets pushed. But a 2025 study published in BMC Sports Science, Medicine and Rehabilitation tracked mental energy in football players across a cohort of 254 male athletes. The authors found something straightforward: mental energy levels predict athletic performance as directly as aerobic capacity does. Managing mental fatigue is another performance skill.

Cognitive health can be structurally supported. Omega-3 fatty acids matter for brain function. Targeted antioxidants reduce the mental fog that follows high-stress training. But the most potent intervention is psychological.

Outcome anxiety is nearly universal among competitive athletes. You perform well, you feel invincible. You fail against a rival, and self-doubt creeps in. The frustration becomes identity: if I didn’t win, what does that say about me?

IRONMAN Master Coach Matt Dixon reframes this exact problem. Before competition, identify three process-focused goals instead of outcome goals. Don’t think “win the race” or “beat my rival.” Think “maintain cadence at mile 3” or “land my first serve 80% of attempts.” Process goals separate execution from identity. When self-doubt tries to surface, you’re already focused on the next rep, the next mile, or the next serve. Self-doubt becomes irrelevant when your mind is fixed on something you control.

#5 Environment: The Variable You Must Account For

Your gym or your training track stays the same. But race day and game day put you in a different environment. Extreme heat, humidity, and technical terrain are some of the environmental variables that change your physical baselines. Your normal training routines won’t be of much use then.

Depending on where you compete, the pollution levels fluctuate, temperature swings widen, and the exposure to infectious disease increases. How your body responds to these stressors determines your result on the event day.

You cannot train in a vacuum and expect to perform in a storm. Your physiology must adapt to external stressors beforehand. Climate-preventive strategies are, in fact, foundational. Design your preparation around the conditions you’ll actually face.

Strategies to Build Holistic Performance

Nutrition, hydration, recovery, and mental focus are not separate issues. They’re interconnected. Here are some strategies that can help:

Optimize Fueling Protocols: Move beyond broad daily calorie counts. Instead, focus on precise post-workout windows. Fuel your body with the right macronutrient combination for your sport, weight, training intensity, and goals. Research shows that eating 20 to 40 grams of protein paired with 1.2 grams of carbohydrates per kilogram of bodyweight within 30 to 60 minutes after training supports recovery. Add targeted supplements to your routine based on what your specific training and lifestyle demands.

Recover Fully: Keep a sleep log specifically during travel. Track not just hours but quality, including wake-ups, restlessness, and morning alertness. Identify whether poor recovery stems from jet lag, pre-competition anxiety, or an actual sleep disorder. Once you know the cause, the intervention becomes clear. Some athletes may need magnesium for muscle relaxation. Others may need melatonin to reset their circadian rhythm. Everyone needs a sleep routine.

Prepare for Environment:Train in the conditions you’ll face. Heat and humidity training teaches you your personal metabolic thresholds. You map out when you need to hydrate, what electrolyte concentration works for your sweat rate, and whether your stomach handles fuel during effort. This intelligence becomes your competition-day strategy.

Audit Your Supplements: If you’re a tested athlete, sports verification certification matters. Look for NSF Certified for Sport or Informed Sport certifications on any formula you consider. Ingredients must match your specific needs. Fillers, additives, unnecessary allergens, and synthetic preservatives should not be a part of your supplement stack.

How to Evaluate Supplement Quality, Transparency and Trust

Sports Nutrition & Performance

The dietary supplement market has changed significantly over the past two decades. Consumers today have access to thousands of products from brands around the world, but having more choices also makes it harder to determine which products meet meaningful standards for quality, freshness, and transparency.

As interest in preventive health, longevity, personalized nutrition, and evidence-based wellness continues to grow, consumers are paying closer attention not only to what a supplement contains, but also to where it comes from, how it is manufactured, how it is stored, and how the company selling it operates.

Why Supplement Transparency Matters

Buying supplements online requires a certain level of trust. Product labels may provide information about ingredients and serving sizes, but consumers may also want to understand how products are manufactured, tested, stored, and distributed.

Important questions to consider include:

  • Where is the product manufactured?
  • Does the manufacturer follow recognized quality standards?
  • Are ingredients clearly listed?
  • Is there information about testing or quality control?
  • How is the product stored before it reaches the customer?
  • Does the retailer provide information about the brands it represents?

Looking beyond marketing claims can help consumers make more informed purchasing decisions.

Understanding GMP Certification

Good Manufacturing Practices, commonly known as GMP, are an important part of supplement quality control. GMP standards are designed to help ensure that products are consistently manufactured and controlled according to established quality requirements.

Consumers researching supplements may therefore want to look for manufacturers that operate under recognized GMP standards. However, a certification or quality claim should not automatically be interpreted as proof that a particular supplement will produce a specific health outcome.

Manufacturing standards and product effectiveness are related but separate considerations.

Does Freshness Matter?

The way supplements are handled after manufacturing can also be important.

Some ingredients may be sensitive to heat, moisture, light, oxygen, or prolonged storage. Poor storage conditions can potentially affect product quality over time, depending on the formulation and ingredient.

This is one reason some supplement retailers use models in which products are shipped directly from manufacturers rather than being held in a retailer’s warehouse for extended periods.

Direct fulfillment can reduce one stage of storage and handling, although it does not by itself guarantee product quality. Consumers should still consider the manufacturer’s standards, expiration dates, packaging, and storage requirements.

The Role of Testing and Scientific Evidence

Consumers are increasingly interested in supplements that have clearly defined ingredients and scientific information behind their formulations.

When evaluating a product, it can be useful to distinguish between:

Ingredient research: Scientific studies may examine individual vitamins, minerals, botanical compounds, or other ingredients.

Product-specific evidence: Research on an individual ingredient does not necessarily prove that every product containing that ingredient has the same effect.

Quality testing: Testing can help verify aspects such as identity, purity, strength, or contamination, depending on the type of testing performed.

Understanding these distinctions can help consumers evaluate supplement claims more carefully.

Personalized Nutrition Is Changing Consumer Habits

Supplement shopping is also becoming more personalized. Rather than taking the same products as everyone else, consumers increasingly look for formulations related to specific interests such as:

  • Healthy aging and longevity
  • Cognitive health
  • Immune support
  • Metabolic health
  • Sports performance
  • Energy and recovery
  • General nutritional support

This trend has contributed to greater demand for products with clearly explained ingredients and more transparent information about formulation and quality.

Buying Supplements Online: What Should You Check?

When purchasing supplements online, consumers can take several practical steps before placing an order.

Check the Manufacturer

Research the company that actually manufactures the product. Look for information about manufacturing facilities, quality standards, and testing practices.

Review the Label

Check the ingredient list, serving size, expiration or best-by date, and any relevant warnings or storage instructions.

Look for Clear Company Information

A transparent retailer should provide accessible information about its business, products, brands, shipping practices, and customer support.

Be Careful With Health Claims

Be skeptical of products that promise dramatic or guaranteed results. A supplement should not be presented as a substitute for appropriate medical care.

Consider Storage and Shipping

Look at how products are shipped and whether the seller provides information about appropriate storage conditions.

A Growing Global Supplement Market

The supplement industry has become increasingly international. Consumers can now purchase products from brands and retailers serving markets across North America, Europe, Asia, the Middle East, Oceania, and other regions.

This expansion gives consumers greater access to different formulations and brands, but it also makes product authenticity, labeling, manufacturing standards, and regulatory requirements increasingly important.

Different countries may have different rules governing dietary supplements, so consumers should understand that a product available internationally may be subject to different regulatory frameworks depending on where it is sold.

What Does a Trustworthy Supplement Seller Look Like?

There is no single factor that determines whether a supplement seller deserves consumer trust. Instead, look at the overall picture.

A transparent company should be willing to explain:

  • Where its products come from
  • Which manufacturers it works with
  • How products are handled and shipped
  • What quality standards apply
  • What information is available about testing
  • How customers can contact the company
  • What its return and refund policies are

For consumers, transparency is ultimately about having enough information to make an informed choice rather than relying solely on promotional claims.

The Bottom Line

The modern supplement market offers more choice than ever, but choosing a product should involve more than looking at a brand name or an attractive label.

Manufacturing standards, ingredient transparency, testing, storage, shipping practices, scientific evidence, and clear company information can all provide useful context when evaluating a supplement.

As consumers become more informed about nutrition and wellness, understanding how supplements are made and sold can help them approach online purchases with greater confidence and more realistic expectations.

Why Do Legs Feel “Busy” at Night – and Can Magnesium Help?

Vitamins, Minerals & Supplements

Do your legs feel “busy” and unsettled as soon as you go to bed? Are leg cramps keeping you awake? Twitchy legs and muscle cramps are surprisingly common and can easily disrupt a good night’s sleep. If this sounds familiar, read on to discover the possible causes, and how magnesium may be able to help.

What are restless legs and night-time leg cramps?

Having restless legs can feel like a tingling or pulling sensation, as if your legs want to move all the time when you’re trying to rest. Some people describe it as a burning feeling, or an itchy, crawling sensation.

Leg cramps can occur with or without “busy” legs. The muscle spasms cause a sharp, sudden pain which can continue to ache after the spasm has eased. Cramps often occur in the calf muscles at the back of the leg, although muscles around the knee and thigh may also be affected.

What causes restless legs and leg cramps at night?

It’s not always clear what’s causing twitchy legs and leg cramps. From a nutrition point of view, muscles and nerves can be affected by dehydration and an imbalance of the electrolyte minerals magnesium, potassium, sodium, and calcium.

How much movement you’ve had during the day makes a difference too. A lot of sitting or standing can affect blood flow and lead to muscle fatigue, which makes muscles more likely to cramp and spasm.

Symptoms can also be associated with:

Side effects of certain medications.
Genetics – other family members may experience similar symptoms.
Pregnancy, especially during the last trimester when it becomes harder to get comfortable during the night.
Stimulants such as caffeine and alcohol.
Stress.

Some people experience symptoms every night while for others, the sensations come and go.

Can magnesium help with restless legs and leg cramps?

If you’re dealing with uncomfortable, twitchy or cramping legs at night, it’s worth checking your magnesium intake. Magnesium contributes to normal muscle and nerve health and is one of the key electrolyte minerals that support fluid balance in the body.

Unfortunately, many people struggle to maintain healthy magnesium levels. Heavily processed foods, excess caffeine and alcohol, and taking certain medications for a long time can all reduce how much magnesium your body absorbs.

How magnesium supports muscle and nerve function

Around one third of all the magnesium in your body is stored in muscles and soft tissues. In muscles, it works alongside calcium to control how muscle fibres contract and relax. In the nervous system, magnesium helps send signals between nerves and keeps muscle movements coordinated, while also preventing nerves from becoming overactive.

Which type of magnesium is best for leg cramps?

Magnesium comes in many different forms and it can be hard to know which one to choose. For leg cramps, we recommend either chelated magnesium glycinate or chelated magnesium taurate.

Magnesium glycinate is magnesium bound to the amino acid glycine. Glycine works as an inhibitory neurotransmitter, which means it has a calming effect in the nervous system . Together, magnesium and glycine offer targeted support for calm, relaxed muscles.

Magnesium taurate is a combination of magnesium and the amino acid taurine. Research into taurine and muscle function suggests it plays a role in energy metabolism and the activity of antioxidant enzymes, especially after exercise. This blend is a good option for leg cramps linked to muscle fatigue and exertion.

When and how to take magnesium for leg cramps

If leg cramps are keeping you awake, we suggest taking magnesium with either your evening meal or an evening snack, a few hours before bed.

When magnesium may not be enough

When dealing with “busy” legs or leg cramps, it’s useful to check lifestyle factors too, along with your magnesium intake. It’s important to stay hydrated throughout the day with plenty of water and herbal teas, and to make sure you’re getting enough movement to support blood flow and circulation to muscle tissues.

Latest Mitopure Reviews from USA

Our team found two detailed reviews on Mitopure and added them to this report:

Marcus Ramsey in his August 2026 Mitopure review said, Really happy with this purchase. The Timeline Mitopure Urolithin A supplement arrived quickly, packaging was pristine, and it’s super easy to incorporate into my daily routine. Premium product all around! I’ve been taking Timeline Mitopure for a few weeks now and have been very pleased with how I feel. High quality, smooth ordering process, and definitely worth adding to a cellular health routine. Highly recommend!

Booksh in latest Mitopure review from USA explained,”’m 81 and have been experiencing days of fatigue after attempting to exercise for the last year. I kept decreasing my exercise trying to find a sustainable sweet spot, finally giving up. After reading the literature on Urolithin-A, I started taking Mitopure at 3 capsules per day six weeks ago. I noticed a significant improvement in energy within a week. Started an exercise routine (Simple Six) four weeks ago. I have much more energy during the day. Consequently the house is much more squared away. I’m sleeping better as an unexpected benefit. I plan on decreasing the dosage to 2 caps per day next month on the assumption that the amount needed to maintain is less than that needed to clear 50 years of accumulation. For me, the big benefit is boosted energy and endurance. I would emphasise that in the advertising.”

The Athlete Who Trains Hard but Can’t Digest Their Nutrition Plan

Sports Nutrition & Performance

You follow a strict training regimen and a nutrition plan measuring down to the milligram of magnesium you take. But if you can’t digest what you consume properly, it’s going to affect your athletic performance.

You aren’t alone because 13.9% to 61% male athletes and 20% to 80% female athletes experience GI symptoms like bloating, stomach upset, etc, according to a 2026 review. The reasons may vary from exercise intensity, duration, dietary intake, and individual tolerance.

In this blog, we give you practical tips that you can easily implement to understand your gut better and adjust your sports nutrition strategy accordingly.

Why Does Sports Nutrition Upset My Stomach?

Sports nutrition may cause stomach upset due to intense exercise, concentrated sports nutrition, dehydration, baseline gut health, and timing of consuming the diet.

Endurance exercise: According to a 2025 mini-review in the Frontiers in Physiology journal, high-intensity endurance exercises encourage more blood to flow into the skeletal muscle. Naturally, it reduces blood flow in the gastrointestinal tract or digestive tract. Over time, this ongoing restriction may cause microdamages to the GI and gut microbiome. Heat stress, dehydration, and physical rhythmic jolting of running activity can further contribute to this gut distress.

Sports nutrition:Many athletes follow an extreme diet that fails to support real-time digestion. Overconsuming or underconsuming nutrients affects the gut flora and leads to digestive troubles. While fiber is great on rest days, try to limit your intake to less than 2 to 3 grams in your pre-workout meal. Swap your usual oatmeal or whole-grain toast for simple, low-fiber options like a plain white bagel with a little honey or a banana. Sports health drinks may contain dairy or fructose, which may cause stomach upset in some athletes. Hypertonic drinks may contain carbohydrates. They can cause digestive discomfort when you drink them during exercise.

Dehydration:Dehydration is a recurring problem for athletes and this can also contribute to digestive issues. If you start your hard training or race poorly hydrated, your stomach may not move the food properly and this causes indigestion.

Gut health: Personalized nutrition supports gut health for athletes. You need a diet that you can tolerate and this can vary from one person to another. Some people may have trouble digesting high-fiber food or high-protein drinks. Knowing what works for you and what doesn’t, well ahead of competition, can help you understand your baseline gut health to strategize a nutrition plan.

Food timing: Any type of nutrition, such as carbohydrates, fiber, proteins, etc., when taken in sudden large quantities, can disrupt digestion. Consuming high-fiber foods before exercise may slower digestion. Simple carbohydrates before exercise provide necessary nutrition without overstraining the gut. Some athletes may not follow the diet plan properly when they aren’t training, and this can also impact gut health.

How Digestive Problems Affect Athletic Performance?

When your gut isn’t absorbing the carbohydrates you eat, you may feel uncomfortable. More than that, your muscles quickly run out of fuel without energy. You may hit the wall faster, meaning your pacing may drop, your perceived effort may go up, and even a moderate pace may feel challenging. Poor digestion can cause:

Fatigue due to poor energy delivery because your body can’t absorb carbohydrates

Dehydration because fluid isn’t absorbed properly and heavy sweating leads to fluid loss

Inflammation due to physical stress on the body and gut

Race disruption due to digestive symptoms like diarrhea, reflux, vomiting, etc

How to Adjust Sports Nutrition for Digestive Tolerance?

Just like the way you train your muscles, you can train your gut. When you consume carbohydrates during a big race, start eating the same food and drinks during weekly training sessions. This helps you build digestive tolerance and lower race-day bloating.

Personalize your nutrition: The diet that works for you should be uniquely designed for you. Even two athletes of the same age in the same sport will have completely different baseline health and digestive tolerance. Consult with a dietary expert to first understand what your body needs and how you can support energy delivery through food. Then, you may choose sports nutrition supplements to support your dietary goals.

Focus on micronutrients: Micronutrients support gut health. Vitamins B, C, D, and E support bacterial gut diversity. Minerals like zinc, calcium, and magnesium also support microbial balance. At the same time, excess intake of certain nutrients like iron or phosphorus may disrupt gut flora. Personalized intake of micronutrients is necessary, and for added support, you can choose from one of the multivitamin supplements designed for athletes.

Include probiotics: Probiotics feed beneficial gut bacteria and may support the gut microbiome. Probiotic supplements provide different strains of bacteria that may support the digestion of your nutritional plan. Aside from helping with digestive symptoms, probiotics may also support daily immunity and energy metabolism.

Hydrate the right way: Hydration is about balanced fluid intake. Hypertonic drinks are packed with carbohydrates and calories. They are more suitable after intense physical exercise. Isotonic drinks have a fluid concentration that matches the body’s natural composition. Drinking them during exercise longer than 60 minutes may help with maintaining glycogen levels for athletes.

Time your meals:The type of food and supplements you take before, during, and after exercise should be customized based on your exercise plan. Similarly, the diet you take on the competition day should be optimized for that purpose. Don’t introduce new food or drink on the competition day.

Choose formulations designed for your needs: When you choose sports nutrition supplements, read the ingredients. Understand if the formulation is designed for you. A supplement designed for a 40-year-old endurance athlete has a different nutritional profile than one designed for active women. If you are a competing athlete who gets tested, you want to avoid unintentional intake of banned substances. In that case, check for NSF Certified for Sport and Informed Sport certification.

Why Recovery is Becoming More Valuable Than Motivation

Sports Nutrition & Performance

Among modern professionals, the output is often associated with motivation. People start telling you to develop better habits, build a stronger mindset, and find ways to push yourself further. The common assumption is that if you push through resistance, performance will follow.

With so many motivational tools, access to podcasts, and expert guidance, the engagement aspect must increase, right? But a 2026 Gallup study shows employee engagement dropped to 20%. This is called quiet cracking, where professionals still want to contribute, but they simply can’t generate the output.

A2026 review that explored the psychological and cognitive functioning of elite athletes found an interesting finding. Burnout and loss of motivation, a psychological aspect, were related to overtraining and not effectively recovering from the cumulative stress of training. For professionals, not feeling motivated may not be related to not having the drive, but may be because you aren’t recovering properly. Let’s explore why you need to shift your focus to recovery.

Why Recovery is Important

Sports science showed sustained overtraining may erode motivation. When professionals are pushing harder to compensate for declining output, they use more coffee, try to muster more willpower, and start using multiple tools for task switching, and all of this adds to systemic stress. You can’t motivate yourself if you aren’t recovering properly.

The psychological feeling and output are directly correlated to your body’s natural stress response. Mental toughness, discipline, and a positive approach can’t compensate when your body is depleted in terms of energy mobilization.

Effort that needs high output, whether it’s physical or cognitive, results in cellular damage. Under normal conditions, your body has antioxidant reserves that can neutralize the free radicals created as a result of stress. But overloading stress on top of stress makes it harder to recover from the stress. When oxidative stress accumulates in the body, recovery takes a hit, and so does your motivation.

How Antioxidants like Astaxanthin Can Help?

A lot of research is concentrated on antioxidants and their relationship with cellular damage. You get antioxidants from fruits and vegetables.

Among many antioxidants, one that’s gaining a lot of attention is astaxanthin. A May 2026 review published inNutrients evaluated 24 randomized controlled trials related to astaxanthin. It was found that astaxanthin reduced creatine kinase markers, which are the primary biomarker of exercise-induced cellular membrane damage. What’s interesting is that the authors found the effect to be more beneficial for post-exercise recovery than for direct performance enhancement. Larger samples and broader trials can explore more about the effects of these antioxidants on recovery and performance.

When you are focused on recovery, the goal is to reduce the backlog of cellular damage to reduce the debt of oxidative stress between sessions of high-demand tasks. This supports your body to return to the natural functional baseline.

AstaReal is a patented form of astaxanthin and the company conducted a clinicaltrial.  It evaluated the most common type of physical and mental fatigue that professionals experience every day. The participants reported fewer symptoms of both physical and mental fatigue and improvements in thinking, motivation, mood, and concentration. While this study used a combination of astaxanthin and tocotrienol, the findings are supportive of astaxanthin supplement usage.

It’s also important to understand that these astaxanthin trials are conducted using a relatively small sample size and long-term studies are yet to be conducted.

How to Recover Properly to Stay Motivated?

There are two aspects that can help explain what sports science calls functional overreaching and non-functional overreaching.

If you take a break from work, go with reduced output, adequate sleep, and no additional demands, and you are able to rebound with energy, sharpness, and motivation, you may be dealing with functional overreaching. This usually responds well to standard recovery with proper rest.

But even after taking a break from work, you don’t feel recovered or feel demotivated to return to your daily schedule, it may mean that extra time or structural support can be helpful. You may be having accumulated stress that takes longer to resolve. In that case, additional recovery support can be helpful to support your daily routine.

To prioritize high-performance recovery, the following tips can help:

Protect your vision and focus: Staring at screens also causes fatigue. A standard recommendation is to use 20-20-20, where you look 20 feet away for 20 seconds every 20 minutes to give a break for your eyes. Dietary sources rich in astaxanthin, like salmon or krill, can be consumed to support eye fatigue.

Engage in exercise: Engage in low-intensity movements like a 30-minute walk. This can help with energy recovery. While overtraining can contribute to additional stress, mild exercises can actually support mitochondrial recovery.

Use light to your advantage: Look at natural sunlight within an hour of waking up and block blue light at night. This helps your body to naturally wake up and wind down for a restful sleep that supports recovery.

Upgrade your nutritional strategy: Eat a diet rich in antioxidants, plant nutrients, and phytonutrients. If your healthcare practitioner recommends antioxidant supplements for you, look for formulations containing well-researched ingredients like astaxanthin supplements.

How to Choose the Right Magnesium for Your Goals

Vitamins, Minerals & Supplements

What does magnesium do?

Magnesium is an essential mineral that contributes to:

Normal muscle function: magnesium and calcium regulate how muscles contract and relax.
The function of the nervous system: magnesium supports nerve transmission and regulates nerve cell activity.
Energy production.
Insulin function and blood sugar balance.
Mental wellbeing.
RNA and DNA formation.
Protein synthesis.

It’s also one of the major electrolyte minerals. Along with potassium, sodium, and calcium, magnesium helps regulate fluid balance in the body.

What is chelated magnesium?

Magnesium needs to be mixed with another molecule to make sure it’s absorbed and utilised by the body. The term “chelated” means that the magnesium is tightly bound to a carrier molecule such as glycine, taurine, or malic acid. The term “chelated” comes from the Greek word for “claw” – the carrier molecule literally claws onto the magnesium!

What does “clean magnesium” mean?

Mineral supplements often contain extra ingredients like binders, fillers, and flavourings to bulk out the weight of the product and give it a certain taste. We use the term “clean” to describe our magnesium supplements because they don’t contain any of these additives. Our products only contain pure chelated magnesium – nothing else.

What are the signs and symptoms of magnesium deficiency?

Common signs that you may need more magnesium include:

Muscle cramps, spasms and twitches.
Fatigue.
Headaches and/or migraine.
Difficulty getting to sleep.
Constipation.
Low appetite.
Nausea and vomiting.
Irregular heartbeat.

It’s important to remember that because magnesium is involved in so many biochemical pathways in the body, low levels can show up differently for each individual.

How to choose the right magnesium for your health goals

If you’re feeling confused by the different types of magnesium, think about why you want to take it. What are your health goals? Keep these in mind as you explore the benefits of each type. Let’s start with magnesium malate…

Magnesium malate – its benefits and uses

Magnesium malate is magnesium bound to malic acid. This is a natural organic acid found in fruits like apples and oranges. Malic acid plays a central role in energy metabolism in the mitochondria – the “energy batteries” inside cells. This activity makes magnesium malate a good option for optimising energy and muscle function.

You can take magnesium malate at any time, though it’s best to use it in the morning if you want to support energy levels through the day. It’s well absorbed, highly bioavailable, and gentle on the gut, making it suitable for even sensitive digestions.

Magnesium taurate – what is it and what’s it good for?

Magnesium taurate is a combination of magnesium and the amino acid taurine. Research into taurine suggests it can:

Support energy production in muscles and the activity of antioxidant enzymes, especially after exercise.
Protect the heart and circulatory system, regulate blood pressure, and support cardiac fitness and vascular health.
Calm and protect the central nervous system.

Like magnesium malate and glycinate, the taurate form is well absorbed and gentle on the gut. The individual benefits of magnesium and taurine are enhanced when they’re combined as magnesium taurate, making this a great option if you’re looking to support sleep, heart health, energy, or muscle function.

Magnesium glycinate – what is it and who is it good for?

Magnesium glycinate combines magnesium with the amino acid glycine. Glycine is known for its calming effect in the nervous system, which is why magnesium glycinate is a good choice to support sleep, emotional wellbeing, energy, and resilience to stress.

Choose magnesium glycinate to optimise:

Energy levels.
Hormonal health.
Mood balance and emotional wellbeing.
Sleep and relaxation.

You can take magnesium glycinate at any time of day, with or without food. If you wish to support sleep, we recommend taking it with your evening meal or an evening snack.

Is magnesium safe to take every day?

Magnesium is safe to take every day for most people who need it. Always follow the recommended dosage instructions as excess amounts of any form of magnesium can lead to irregular heartbeat, very low blood pressure, and muscle weakness. If you are pregnant, breastfeeding, or taking prescription medications we recommend you speak to your doctor before using any type of magnesium.
