Creatine: The Complete Guide

Creatine is the most researched performance supplement in sports science — and one of the few that works as advertised. This guide cuts through the form confusion, loading myths, and marketing noise to give you the evidence-based picture, with links to every in-depth review we've published.

Key Takeaways

  • Creatine monohydrate is the most studied sports supplement ever — hundreds of RCTs confirm its safety and efficacy.
  • Creatine HCL requires a smaller dose but has no meaningful evidence advantage over monohydrate for strength or hypertrophy.
  • Loading phase (20 g/day for 5–7 days) is optional — 3–5 g/day produces the same saturation over 3–4 weeks.
  • Creatine supports brain health: raises phosphocreatine levels in the prefrontal cortex, improving working memory and reducing mental fatigue.
  • Women benefit equally from creatine — body composition, strength, and recovery — often at slightly lower absolute doses.
  • Creatine is not a stimulant. It works by expanding the phosphocreatine pool for ATP regeneration during high-intensity efforts.
