Evidence-backed FAQ
What creatine doses have been studied, and is loading required?
Direct answer
A loading phase is not required to raise muscle creatine stores. In one controlled study, about 20 g/day for 6 days reached the target faster, while 3 g/day reached a comparable increase over about 28 days.[1], [2]
What the evidence shows
The main difference between the studied approaches was time to muscle-creatine saturation. About 2 g/day maintained an already elevated level in the same study.[1], [2]
Important limitations
These are study protocols, not personalized dosing advice. The central study involved 31 healthy men and measured muscle creatine rather than performance or a clinical outcome.[1], [2]
