What creatine does
Creatine supports phosphocreatine recycling in muscle, which matters for repeated high-intensity efforts. It is not a stimulant and does not replace training or nutrition.
What the evidence supports
Creatine monohydrate has substantial human evidence for strength and high-intensity performance in many populations. Effects on cognition exist but are smaller and more context-dependent. BOTH classifies standard creatine monohydrate as ESTABLISHED for its core performance use cases.
Who it is for — and who should pause
Often useful for people doing regular strength or high-intensity training who want a low-cost, well-studied ergogenic aid. Anyone with kidney disease, on relevant medications, or with clinician-directed restrictions should confirm suitability before use.
What to look for when buying
Monohydrate form, minimal ingredients, third-party testing where possible. Fancy delivery systems rarely beat plain monohydrate on evidence. BOTH will link partners only after URL and claims verification.
