Creatine monohydrate is the most researched and proven supplement in existence — over 700 studies and counting. The benefits go beyond muscle: cognitive function, cellular energy, neuroprotection, and recovery. 5g per day is the clinically validated dose. Pure creatine monohydrate beats every other form (HCL, ethyl ester, buffered) on cost, evidence, and absorption.
We compared the 5 best creatine monohydrate powders on Amazon — micronized for solubility, third-party tested for purity, and ranked by price-per-serving.
