Sugar-free NASA-developed hydration designed to propel your everyday life.
After finding that astronauts were experiencing severe dehydration in space, NASA sought to fix the problem. They patented a powerful isotonic solution very high in electrolytes to keep astronauts well hydrated and at maximum performance during their missions. Utilizing the learnings from NASA's expired patent, we developed Lightspeed. Learn More >

Isotonic powder mix designed for rapid hydration with a high concentration of electrolytes and zero sugar.
Your bloodstream maintains an osmolality that hovers between 275-295 Omol/L. Because of this, it can only absorb liquids within this range. Anything outside of that, your body must compensate to absorb it. The less water in your bloodstream, the greater the osmolality. More water results in lower osmolality. In order to hydrate most efficiently, use an isotonic solution. Isotonic solutions match the osmolality in your bloodstream, allowing for maximum absorption. Our isotonic solution – based off of NASA’s rehydration formula – is precisely designed to match your blood’s osmolality so that it can be rapidly absorbed without modification in your stomach.
