Osmo Active Hydration for Women is a during exercise hydration drink that was scientifically developed to be the fastest way for women to rehydrate. In the past, the majority of human performance research was conducted on men, with the assumption that this was directly applicable to women. However, women have hormonal fluctuations that result in physiology challenges to exercise, metabolism, recovery, and training. Our products for women are based on scientific studies conducted on women; they uniquely address the needs of female athletes and deliver proven benefits. Get the nutrition that matches your physiology and see how great you feel and perform. Active Hydration for Women has been developed by Dr. Stacy Sims, MSc, PhD, Exercise Physiologist Nutritional Scientist, CISSN.
