Creatine monohydrate at 3–5g/day saturates muscle stores in 3–4 weeks; loading (20g/day for 5–7 days) accelerates this. For larger individuals (90kg+), 5–10g/day maintenance may be optimal. Cognitive benefits are strongest in sleep-deprived individuals, vegetarians, and older adults. Safety data supports doses up to 30g/day long-term with no adverse effects on kidney or liver function.
