Creatine: the most misunderstood scoop in fitness

Creatine monohydrate is the most studied supplement in sports science. Hundreds of trials, decades of data: the research consensus (including the International Society of Sports Nutrition's position stand) is that it works and has a strong safety record in healthy adults at studied doses. It is not a steroid, a hormone, or magic.

What it does: tops up your muscles' rapid-energy system, so you squeeze out an extra rep or two. Over months, those extra reps compound into real strength and size. The dose used in most studies is 3–5 g daily. Timing doesn't matter. No loading phase needed. If you have a kidney condition or take medication, talk to your doctor first. This article is general information, not medical advice.

The myths

Studies in healthy adults have not found kidney damage at recommended doses. It doesn't need cycling. The "bloating" is mostly muscle cells holding water, which is literally part of how it works.

It's also cheap. If a supplement costs more than creatine and promises more than creatine, be skeptical.
