A comprehensive new study has evaluated the effectiveness of the most popular creatine supplements on the market, finding significant differences in absorption rates and purity between brands. Creatine monohydrate remains the gold standard according to the findings.

Researchers tested 15 leading products and found that several premium-priced options offered no measurable benefit over basic creatine monohydrate. The study recommends consumers focus on purity and third-party testing rather than marketing claims.
