Momentous Creatine Monohydrate

The boring supplement with the largest body of research — and the brand most longevity clinicians actually recommend.

Creatine monohydrate is the most-studied performance and longevity supplement in existence. The data on muscle function, cognitive performance, and (for women specifically) bone density is robust enough that it's become standard recommendation territory.

Buying creatine isn't complicated, but where you buy it matters more than people think. Cheap creatine is often un-certified, sometimes contaminated, and frequently not actually monohydrate. Momentous is NSF Certified for Sport — meaning it's tested for banned substances and verified for label accuracy — which is the bar most longevity clinicians use as their threshold for "yes I'll recommend this."

The Momentous price ($0.40/serving) is roughly 2x bottom-of-the-barrel creatine and 50% less than premium-brand creatine. For a daily supplement you'll take for years, the certification overhead is worth it.
