SOS Rehydrate was founded by a board-certified physician, a military veteran, and an elite athlete who discovered that electrolytes and minerals could make water more hydrating. Their doctor-formulated products have 80x less sugar than sports drinks, only 3g carbs, and 10 calories. With SOS, you can hydrate 3x faster than water alone and replenish lost electrolytes to feel energized. Plus, their new Daily Hydration line includes essential vitamins for daily wellness.
