The science
The supplement most people haven't
started.
Over a thousand clinical trials. Thirty years of evidence. And until recently, a branding problem.
What is creatine?
Creatine is a molecule your body already produces, found naturally in meat and fish. It powers your muscles' immediate energy reserve — the system that fires when you lift something heavy, run hard, or need your brain sharp at 3pm.
It is the most studied supplement in sports science. Over 1,000 clinical trials. Consistent findings across muscle performance, cognitive function, and healthy aging.
The reason most people haven't started is simple: it was marketed to competitive athletes and bodybuilders. That story is outdated.
What the research shows
Especially for women
20–25% lower
baseline stores.
Women have naturally lower creatine stores than men — around 20–25% less. That gap means supplementation has more room to work.
A 2025 review across the full female lifespan documents benefits in muscle maintenance, cognitive performance, mood, and bone health. The 2025 CONCRET-MENOPA randomised controlled trial — specifically for perimenopausal and menopausal women — found creatine superior to placebo for reaction time, frontal brain creatine levels, and potentially for reducing mood swing severity.
For women who don't eat red meat, the gap is even wider. The only dietary source of creatine is animal protein. Without it, supplementation is doing more work.
The myths
"Will it make me bulky?"
No. Creatine supports the muscle you're building — it doesn't add mass on its own. In the first week some people gain 0.5–1 kg. That's water inside your muscle cells, not fat, and it doesn't affect how you look. It reverses within a few weeks if you stop.
"Is it bad for my kidneys?"
No. Two decades of clinical research — including studies in people with one kidney — show no adverse effect on kidney function at standard doses. This myth comes from confusing creatine with creatinine, a different molecule that shows up in bloodwork. They sound similar. They're not the same thing.
"Isn't this for serious athletes?"
It was marketed that way. The research tells a different story. Benefits extend to women at every life stage, older adults, people who want sharper thinking, and people who don't eat meat. The science moved. The marketing is catching up.
One drink a day.
That's all it takes.
