Creatine
Evidence grade: Essential
A naturally occurring compound made from amino acids that supports energy production in cells by replenishing ATP stores. Stored primarily in muscle and also in the brain as phosphocreatine, it buffers short-term energy demands and supports cellular resilience.

How to practice Creatine
Take at least 5 g/day of creatine monohydrate; newer evidence indicates 10 g/day, split into two 5 g doses (morning and afternoon), may better support brain saturation since muscles absorb most of the first dose. Recent evidence suggests a higher dose up to 20g may offer value in sleep deprived individuals or those with early Alzheimer's. Dissolve into warm water (not too hot which can degrade the creatine) or mix with a carbohydrate-containing meal to enhance uptake. Stay hydrated to reduce mild GI discomfort. No loading phase or cycling is necessary. Safe for long-term use in healthy adults; those with kidney disease should consult a clinician before supplementing.
The evidence behind Creatine
Creatine enhances mitochondrial energy availability and stabilizes neuronal energy during stress. One of the best studied supplements in the world - dozens of RCTs confirm benefits for muscle performance, mood, and cognition, especially in vegetarians, older adults, and people under sleep or metabolic stress. Brain-imaging studies show improved ATP turnover and oxygen efficiency. Emerging data suggest that standard doses mainly saturate muscle, while higher intakes may more effectively raise brain creatine levels. Safe, well-studied, and cost-effective.
