Women naturally possess lower creatine stores than men and should therefore prioritize high-purity supplementation, free of impurities, to optimize its benefits for muscle, brain, and gut health.

Creatine is indeed one of the most studied compounds, with a strong consensus on its role in cellular energy production (meta-analysis, Journal of the International Society of Sports Nutrition). The assertion that women have lower endogenous stores is supported by observational studies, often correlated with lower muscle mass and different dietary patterns. However, the idea that a smaller "margin for error" necessitates exceptional purity is a marketing extrapolation: standard creatine monohydrate, when certified, already exhibits an extremely high level of purity. While vigilance regarding quality is always recommended to avoid contaminants (toxicology studies), the risk associated with standard products is often overstated by brands to justify specific formulations. There is no robust evidence suggesting that trace impurities present in products compliant with standards significantly impact physiological efficacy in women.
