Ready for your active lifestyle, the Osmo Women's Hydration Singles 24 Count Box contains single serving drink mix packets for in workout hydration. Developed by Dr. Stacy Sims, an accomplished triathlete and road cyclist, this drink mix is catered toward female athletes, with the approach that Women are not small men. That's not to say that women don't have the same athletic potential as their male counterparts, but she's specifically referring to the physiological differences, mainly hormonal fluctuations, that require a different approach to in workout hydration. Until recently, most workout nutrition supplements were tailored to the needs of men, with male research and testing performed to back up products' performance claims. As such, women's supplements were given a shrink and pink treatment, with pretty colored packaging, scaled down calories, added soy protein, and maybe a bit of added calcium. Not here. The Women's Hydration Singles mix approaches workout hydration for female athletes in a much different manner than the competition. Since it's tailored to the needs of female athletes, the Women's Hydration Singles mix is designed to counteract the effects of the menstrual cycle on performance. Namely, the fact that a woman's internal temperature varies by 0. 5 degrees Celsius during her menstrual cycle, while sodium losses increase and plasma volume drops. As such, this hydration mix helps you avoid premenstrual related performance decline, while increasing overall power output and endurance. Each box of Women's Hydration Singles comes with 24 single serving packets, in either Mango or Strawberry flavors. One packet mixes with 16 ounces of water, allowing you to simply grab a single packet and head to the gym or trail head with minimal fuss.
