What we think

Your Hydration Should Match Your Intensity… 

When you know you’re going for a Big Effort -- training in the heat, long duration, or max power -- set your body up the right way by preloading it with plenty of hydration.  Here’s how… 

 In high-intensity scenarios, your body will lose water faster than you can replace it. Prepare yourself by boosting blood plasma levels by 8-11% before you exercise with PreLoad from Osmo Active, a rapid hydration mix formulated for perfect osmolality. 

By boosting plasma levels and sodium stores hours before you being to sweat, you’ll increase your blood circulation so that you can diffuse body temperature for better performance and less cramping, even in hot conditions. Don’t just hit the heat hoping not to be beat -- prepare by PreLoading. 

PLEASE NOTE: This mix is for serious athletes only! Its high salt content is intended to replace what you lose during high-intensity sessions where you are going to have extreme sweattage. Talk to your doc before using if you have high blood pressure.  

How It Works

Made with all-natural ingredients and whole fruit for a light and delicious flavor, PreLoad is designed to give your blood plasma and sodium levels a major boost before you exercise, setting you up for better blood circulation so that you can diffuse temperature more effectively and experience less cramping, even in the sweltering heat.  The best way to prepare? PreLoad. 


Osmo PreLoad primes your body for high-intensity effort and hot conditions.

  • Increases blood plasma volume for better circulation

  • Regulates your body heat, delaying fatigue

  • Reduces cramps with sodium bicarbonate to buffer lactic acid

  • Powers your aerobic metabolism with sodium citrate

How To Use 

Mix PreLoad with water and drink the night before and the morning of an intense effort so you can start your event fully hydrated and feeling great.

Have you heard of OSMOLALITY? 

You’ve probably read plenty about how important hydration is to performance. But you may not have heard of how important osmolality is to optimal hydration. So here’s a quick primer -- 

The official definition of osmolality is the concentration of a solution expressed as the total number of solute particles per kilogram. 

Essentially, how many particles of “things” (solvents) are in a liquid. The more “things,”  the higher osmolality. The fewer “things,” the lower. 

Now the reason why this matters is that if your hydration drink has a high osmolality (think high-calorie drinks, for example), it may actually be pulling liquid away from your cells and muscles and into your stomach, reducing power in your muscles and contributing to that sloshy feeling. Here’s why… 

When you consume a high osmolality liquid, it will enter your stomach and stay there for a while instead of passing immediately into your bloodstream and interstitial fluid (the fluid between your cells). This is because it needs to go through some level of “digestion” to remove the extra “stuff’ (solvents) before it is at a concentrative match to your blood plasma. Only when it is a match in osmolality to your own natural liquids can it be utilized as a hydration source. 

What’s more, during this digestive process, your body will actually pull liquid away from your working muscles to be used in the breakdown and dilution of the liquid! This is why consuming high-calorie drinks and syrupy gels can have a negative effect on many athletes and lead to dehydration! 

The Solution

The solution is to consume liquids that are a MATCH to your blood plasma osmolality. When you do this, science shows that the liquid will go into your stomach and then immediately pass through your lining into your bloodstream and the interstitial fluids surrounding your cells. This means you will get instant hydration and no strain or drop in hydration because you won’t be pulling any precious liquids away from your muscles!  

This is why osmolality can be such a key factor in whether your hydration is working for you or against you! 

But, What About Energy? 

Now, I know what you’re probably thinking… but what about my calories?? We all know that when you’re training hard, running, cycling, climbing, whatever it is, you’re burning through your calories like there’s no tomorrow. Obviously, you need some way to replenish to keep going. 

The makers of Osmo agree with this! However, they have an interesting saying which is: “food in your pocket,  hydration in your bottle,” meaning athletes should not rely on liquid calories for their fuel source: calories should be eaten, and one should drink for hydration.

This does go against a widely held belief 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, blood sugar and hydration will be optimized, and uncomfortable side effects like bloating, sloshing, and GI distress are avoided.
