Creatine: The Body’s "Universal Battery" (and it’s not just for athletes)

If you’ve ever dismissed creatine as a "gym-bro" supplement or something only for women’s fitness trends, the science is revealing its fast becoming an essential part of any health and wellbeing stack. 

While it’s commonly known for building muscle, research is continually revealing creatine is more like a foundational health nutrient and is fast becoming a household supplement for all ages. Creatine is safe, effective and one of the most researched supplements on the market. Creatine powers your brain, protects muscle and bones, and keeps you sharp as you age.

The Ultimate Brain Fuel – your brain contains 5% of your body’s stores of creatine! 

Your brain is a massive energy consumer, using up to 20% of your body’s daily calories. Creatine helps replenish and provide the fuel it needs to stay mentally alert.

• Mental Sharpness: Studies show it can improve memory and processing speed, especially when tired or stressed.
• Memory & Processing: A systematic review of 16 randomised controlled trials (RCTs) found that creatine supplementation significantly improves memory and information processing speed in healthy adults.

• The "Vegan Gap": Since creatine is mostly found in meat, people on plant-based diets often have lower levels. Supplementing can provide a noticeable "lift" in mental clarity for vegetarians and vegans. In fact, vegetarians and vegans will benefit from taking creatine the most

Healthy Ageing of body, bone and brain

As we age, unfortunately we naturally lose muscle mass (aka sarcopenia) and bone density. Building lean muscle mass is essential to help maintain the muscles attaching onto our structural framework (our skeleton) keeping it mobile and strong. Having muscle mass goes far deeper than looks, it provides strength and metabolic flexibility to help us move, avoid falls and ultimately stay independent. Having stronger muscles pulling on our bones stimulate the bone to lay down more bone to tolerate the load, this in tern leads to denser stronger bones, essential to help prevent osteoporosis.

• Bone Strength: When used alongside any exercise, creatine helps keep bones dense and strong. Its particularly beneficial when used alongside lifting any form of weights.
• Muscle Quality: It helps maintain the muscle quality needed for essential daily tasks  and exercise.

Stress and Sleep Support.

Bad night’s sleep? Avoid the "brain fog" that can occur from a bad night's sleep. Research indicates that creatine can act as a buffer, helping the brain function better even when you are feeling sleep deprived. It helps maintain cellular energy during times of physical and mental stress providing greater memory and processing speeds. 

Is It Safe?

• Creatine is one of the most studied supplements. For the average healthy adult, it is considered incredibly safe. Some individuals report of a small amount of water retention in the muscles at the start of taking creatine but this is rare and soon subsides after several days consumption. 
• Long-term studies (up to 5 years) have shown no adverse effects on kidney function or overall health in healthy individuals.

How to take creatine. Consuming a consistent daily amount of Creatine Monohydrate is considered the most effective approach for maintaining elevated muscle and brain levels. The specific timing of ingestion appears to be less significant than daily consistency, so avoid the fuss and just take it - at any time! 

Dose: A daily maintenance dose of 3–5 grams of creatine monohydrate powder is the most effective and affordable form.

Food sources of Creatine

Creatine is found naturally and almost exclusively in animal-based proteins, specifically in the skeletal muscle of fish and animals. While your body can produce about 1 gram of creatine daily from amino acids like glycine and arginine, consuming it through food is an effective way to maintain higher stores. 

Top Creatine-Rich Foods

The following foods are ranked by their approximate creatine content per kilogram of raw product:

Important Dietary Considerations

• Cooking Loss: Creatine is heat-sensitive; high-heat cooking (like long boiling or heavy charring) can reduce the amount of creatine available..
• The "Vegan Gap": There are no direct plant-based food sources of creatine. Vegans can instead focus on "precursor" foods rich in Arginine (seeds, nuts, legumes), Glycine (spinach, seaweed), and Methionine (tofu, quinoa) to help their bodies naturally synthesise it.
• Dairy and Eggs: These contain only trace amounts of creatine (e.g., milk contains approximately 0.02g per 100g), making them insufficient as primary sources.
