Creatine Monohydrate: The Most Researched Supplement, Explained Simply

What it actually does

Increases the availability of ATP, your muscles' quick-energy currency, allowing slightly more power and reps per set — which, compounded over months of training, contributes to greater strength and muscle gains.

Addressing the kidney damage myth

Extensively studied in healthy individuals with no evidence of kidney harm at standard doses. The myth largely stems from confusing elevated creatinine (a normal, harmless marker) with actual kidney damage — they aren't the same thing.

How to actually take it

3-5 grams daily, any time of day, consistently. No loading phase or cycling is necessary — the classic 'loading week' speeds up saturation slightly but isn't required for the supplement to eventually work.

Who should be cautious

People with pre-existing kidney conditions should consult a doctor before starting, as a general precaution — otherwise, it remains one of the safest, most well-studied supplements available for healthy adults.
