Like all Ultima Replenisher products, our first and foremost goal in formulating is to keep it natural. Then, we make sure to minimize carbs just enough to allow for rapid absorption. With zero sugar and a complete balance of all 8 essential electrolytes, Ultima Replenisher is the finest energy and hydration product around. Grape is our first flavor to provide vitamin C from real fruit. It also has grape skin for color, which is rich in antioxidants. It can be enjoyed hot or cold and with only 5 mg of sodium, it is the perfect all-day, everyday health drink.
