The Osmo Women's Hydration specifically targets a women's physiology, delivering maximum hydration during regular exercise sessions. 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 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 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 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. This workout hydration mix comes in Mango and Strawberry flavors, and like most drink mixes, its dosage is dependent on how much water you mix it with. Add 2. 5 scoops to 20 ounces of water or 3 scoops if you're drinking 24 ounces of water during workout sessions.
