Why does Acute Recovery use two types of protein?

Acute Recovery uses two proteins, whey isolate and micellar casein, that are proven to halt muscular breakdown post-workout. Whey is a fast-acting protein, while casein is a long-lasting protein. The combination of the two is highly effective; muscles have access to amino acids over several hours, enabling optimal muscle repair.

How is your Optimized for Women line different from the standard mix?

Our Optimized for Women mixes are uniquely formulated for women, based on peer-reviewed science conducted on female athletes. Until very recently, most of the data collected in case studies regarding nutrition and training were conducted almost entirely on men. However, what works for men isn’t automatically effective for women. Hormonal fluctuations throughout the menstrual cycle do have an impact on women’s hydration levels and recovery time (see our Science page for more information). The Optimized for Women mixes were made to help female athletes achieve peak performance at any point in their cycle; however, women who simply want to benefit from better hydration and nutrition can use the standard Osmo mixes and still experience improved performance. If you are an elite female athlete and every second of your race time counts, the optimized mixes can make a crucial difference.

Do you recommend eating gels while drinking Osmo products during exercise?

No. Gels are not a good thing to consume during exercise because they are a concentrated carbohydrate that goes into a dehydrated gut.

When you eat a gel, you change the osmotic pressure in your digestive tract, which in turn stimulates the body to shift fluid out of the plasma and other spaces to dilute the gel in order for it to be absorbed. This is a process that slows the rate of fluid transfer into the body leading to dehydration.

However, chews and jellybeans are fine to eat during exercise because they solid and are consumed at a slower rate than gel. They also deliver a smaller amount of carbohydrate per bite so you get a continuous input and a smaller dose of carbohydrate than when you swallow a gel.

What kinds of food do you suggest that I consume with your products?

We like to recommend starting with solid foods and working your way to semisolid options. By this we mean, start by eating something like salted potato cubes, sandwich bites, pretzels, low-fat muffins, or mini cookie bites. If you need to have “engineered nutrition,” we suggest protein-oriented bars, such as Clif MOJO, uncoated Luna bars, or MacroBar. Semisolid foods are your favorite childhood gummy-type candy, such as jelly beans, Swedish Fish or Mike and Ikes. They may not be the most nutritional fare, but they are mighty tasty.

What do you mean by "food in the pocket, hydration in the bottle?"

This phrase is a key part of the Osmo Nutrition philosophy and the specific blueprint for developing Osmo Active Hydration. What we mean is that an athlete should not rely on liquid calories for their fuel source: calories should be eaten and one should drink for hydration.

One widely held belief in the fitness/athletic/performance industry is that liquid calories are the best way to hydrate and fuel for a race. However, by using solid food for energy and liquids for hydration, both blood sugar and hydration can be optimized and uncomfortable side effects like bloating, sloshing and GI distress can be avoided.

What is the difference between Osmo Active Hydration and other hydration mixes on the market?

Osmo Active is more effective than other sports drinks because it is developed based on leading, established, and published scientific research to maximize fluid absorption in the body. Unlike other sports drinks, Osmo is made with natural, organic ingredients. Most sports drinks are made to be calorie-heavy, but this slows the rate of hydration. Instead, Osmo Active is optimized for hydration with sucrose, glucose, and sodium working to maximize your body’s fluid absorption. Our lower carbohydrate percentage, at 3.5% compared to the average 6-8%, ensures that you don’t get residual “slosh” in your stomach from delayed gastric emptying. Our goal is to educate athletes about “food in the pocket, hydration in the bottle.”

Visit our Science page for more information.

If I want to try just one of the three Osmo drink mixes, which one should I start with?

We recommend starting with Osmo Active Hydration. This is the product we developed for use during exercise and it’s a great way to experience the Osmo difference. This product maximizes fluid absorption, delaying power decline and fatigue and reducing “sloshing” in the stomach that is caused by traditional sports drinks. Try Osmo Active during a workout or race, and you will quickly see an improvement in your performance.

How do I know if I'm properly hydrated when exercising?

A good way to determine whether you’re properly hydrated is to examine the color of your urine first thing in the morning and to monitor the level of your thirst before, during, and after you exercise. When gauging urine color, the rule is generally the clearer the better. Dark yellow urine is a telltale sign of dehydration. Pay attention to hydration in conjunction with exercise intensity, exercise duration and weather conditions so you can adjust your optimal rate of fluid consumption for different situations. Our Whizz Wands can help you monitor your hydration levels.

How much do I need to drink to stay hydrated?

Individual body water loss varies among athletes and according to intensity and weather conditions. Most people, under most conditions, should drink 20-25 ounces of Osmo Active Hydration per hour of exercise (roughly one water bottle). Lighter athletes or athletes exercising in cool weather conditions may only require 16-18 ounces an hour. Larger athletes or athletes exercising under hot and humid conditions may require up to 30 ounces or more an hour.

How long will it take me to notice a difference in my performance after I start to drink Osmo products?

We believe you will see a change in your performance the first time you use any Osmo product. There is no need to experience Osmo products over a long period of time to see how they change your performance, but you will certainly experience their benefits by the time you reach the bottom of the tub. Some may immediately notice that they no longer experience cramps on long rides or runs. Others who normally exercise in a hypo-hydrated state will see an improvement in their performance after using Osmo Active Hydration. Those who use Osmo Acute Recovery will find that they recover from exercise more quickly.
