Don’t let the heat cramp your style.

Dr Stacy Sims, the mastermind behind Osmo’s science, has worked to create a series of drinks that help your body achieve optimal performance. The Osmo PreLoad Hydration is specifically designed to keep your body in tune in the most extreme of conditions.

What you may not realize is that when your body heat goes up, not only do you feel hot, your body’s internal systems start to be compromised. This occurs not just because of the heat, but because your body rapidly loses hydration through sweating. The PreLoad works before exercise to increase total body water and plasma volume, provide a buffer for lactic acid, and increase the cofactors needed for aerobic metabolism. This is called "hyperhydrating," and while you won’t need it for every event, with temperatures gradually climbing, it’s a good piece of nutrition to have in your bag of tricks. In addition to helping your body maintain its hydration levels, hyperhydrating keeps your sodium stores from being washed out by excessive water consumption. Because of this, PreLoad also works to minimize cramping. The addition of sodium citrate and sodium bicarbonate has been thought to help buffer the effects of lactic acid during intense training and efforts. Osmo recommends consuming PreLoad the night before and morning of an effort requiring maximum hydration and metabolic buffering.
