Why it's on the short list
Creatine sits alongside EAA, vitamin C, and vitamin D3 as one of the few supplements that genuinely earns its place in a recomposition plan, not because it's trendy, but because the evidence behind it consistently holds up.
The part most people miss
Creatine's reputation is built almost entirely on muscle and strength, but cognitive performance benefits from it too. That's a real reason to consider it even for someone whose primary goal isn't physical performance.
