Creatine Is Cheap, Safe, and Remarkably Well-Studied

One of the most researched supplements — and not just for gym bros.

Creatine has a meathead reputation. The evidence says it's one of the few supplements genuinely worth considering for a lot of people.

What the research shows

Creatine is among the most studied supplements in existence, with a strong safety record. It reliably helps with strength and muscle, but newer research also points to benefits for brain function, especially under fatigue or sleep deprivation. Interest is growing for older adults and cognition too.

Simple and inexpensive

Plain creatine monohydrate is cheap, and it's the form nearly all the research uses — you don't need fancy blends or "loading" rituals. A few grams a day is the standard.

The move

If you're active, aging, or just want a well-supported option, creatine monohydrate is a rare supplement with real evidence behind it. Stay hydrated, and check with a doctor if you have kidney concerns.
