Active hydration for active women

"Women are not small men." This is the statement that is behind the Osmo Nutrition's women's formulas. Dr. Stacy Sims, the scientist behind Osmo, isn't referring to their potential as athletes. Dr. Sims is referring to, specifically, a woman's physiology. She developed Osmo Active Hydration for women to rebalance physiological differences and help women obtain and maintain peak performance, no matter what the day of the month is.

Although her phrase seems blatantly obvious, for years sports nutrition manufacturers have been treating women as just that -- small men. Sure they've reduced calories in drinks, added soy protein, and packaged them in pretty pink boxes, maybe added a bit of calcium. But, there has been no move to reformulate from a science-based standpoint. Sims, an elite athlete and specialist in how hormones affect the body's performance set out to develop a series of hydration and recovery products that directly address the female athlete's needs.

What's the one thing that affects a woman more than anything? The menstrual cycle. Basically, Sims describes the hormonal flux as occurring in two phases: During the two weeks when the body is at low hormones, women are physiologically similar to men in both metabolism and carbohydrate uptake. During the two weeks of high hormones, however, there are significant differences. High estrogen forces a woman's body to spare glycogen and increases the amount of fat used for fuel. And while this may sound like a good thing -- who doesn't want to lose a few pounds --if you are racing or doing zone 5 intervals, this can have devastating effects. Additionally, high progesterone delays sweat response and increases core temperature, increases sodium loss and increases muscle breakdown. The combination of these hormones decreases blood plasma volume which can make efforts feel harder than they are.

Osmo Nutrition's Active Hydration for Women is designed to counteract the effects the menstrual cycle has on performance. Yes, the formula is based on the science behind Osmo's Active Hydration Formula for men, but it is not a shrink and pink version. The original formula cuts right to the core of Osmo's founding hypothesis and namesake -- the importance of osmolality and the types of sugars that're used in beverages.

So, what is osmolality? Basically, it's the amount of solutes within a solution, and for the purposes of hydration, we view the blood plasma and the drink itself as solutions. Blood's osmolality sits around 280 to 295 mOsm, while Active Hydration is around 265-270 mOsm. Now, let's get into why this important. Osmo works by looking at how actual physiology works. Around 95% of water absorption occurs at the small intestines. And what facilitates this absorption into the body is a combination of sodium, glucose, and sucrose -- all in small amounts. combining specific sugars and sodiums with water in order to accelerate fluid absorption. But, whereas most industry mixes maintain too high a ratio of sugars to sodium, effectively slowing down absorption, Osmo's proprietary ratio actually accelerates fluid absorption with the three components maintaining a 3.2% solution. Through extensive research, Osmo discovered that fluids that have an osmolality greater than 290 mOsm, and are comprised of fructose, maltodextrin, and sucrose, create a solution that actually inhibits water absorption and hydration potential. As a result of this optimal range, Active Hydration removes the common, unwanted side effects found in typical hydration mixes. That's right, we're talking about the sloshing, bloating, and other gastrointestinal distresses that arise from not being able to properly absorb fluid.

Using the basis of the original formula, in the formula for women, Sims has optimized the ration of glucose to sucrose plus added greater sodium which helps offset decreased plasma volume. When the body temperature increases during the menstrual cycle, muscles are compromised as the body must work to keep the core temperature down rather than maximizing muscle efficiency. The proprietary Osmo formula works to offset this fatigue so that you perform your best no matter what day of the month it is.

Not only does Active Hydration bolster your output, but it's also comprised of high-quality, natural, and organic ingredients. So, not only are you assured that what you're drinking is healthy, but more importantly, you won't experience the flavor fatigue that's all-too-common with the majority of hydration mixes. This means that every sip from the bottle will feel new, tasteful, and refreshing.

The Osmo Nutrition Active Hydration for Women is available in a 40ounce serving tub in Mango.

Taste: A light, perfectly Mango Flavor

  • Familiarity: I've used it once or twice and have initial impressions

I was pleasantly surprised by the mango flavor. It really tastes like mango! I wouldn't say it has a fake taste at all. I'm really impressed!

Fine, if you like Mango

  • Familiarity: I've used it once or twice and have initial impressions

Gave it a go, but I found I'm not that fond of the Mango flavor. It's not a strong flavor, and not sweet but I prefer the taste of Skratch.

Trumps water

  • Familiarity: I've put it through the wringer

I love this drink mix!

I have never really used drink mixes while riding. I have always preferred water, not because I didn't believe the benefits of electrolytes during training, but because so many of the ready-made and drink mixes that I have tried left my gastro-intestinal tract mumbling and grumbling in dismay.

OSMO's Active Hydration mix is different. While it contains the necessary salt and other ingredients known to positively affect performance, it does so in a ratio that is easily absorbed into the body. This way I wasn't stuck with an overload of sugars in my system. The result was no GI issues. I never cramped or felt fatigued. In addition, the taste is a very pleasant mango flavor that isn't overwhelming.

OSMO's Active Hydration is my choice from now on.
