Pre:play has the same electrolyte profile as re:play equivalent to an IV bag or 10 bottles of the leading sports beverage but has the 200 mg of time released caffeine. Caffeine allows your body to burn fat as a fuel source when performing endurance events versus burning glucose. Hydration Health Products use a formula developed from 40 years of scientific research. With an isotonic delivery system, our products were designed to replace fluids in extreme situations where a medical IV isn't available. Our mission is to improve and support the condition of active people and athletes by combating dehydration in their activities and defending them in heat stressed environments. We will advance the science of hydration and bring forward products that will support and improve the user at the gym, playing field or workplace. You can stay strong with pre:play’s sugar free IV strength electrolytes (over 2,500mg/serving), L-Glutamine (5.5 grams per serving), immunity boosting RDA of Zinc (70%), pre and probiotics, 200 mg of time released caffeine for subtle sustained energy with no crash, and 6 grams of L-Arginine AAKG vasodilator.
