Replenisher Daily Electrolyte Drink Mix

Ultima Replenisher is a zero-calorie, zero-sugar electrolyte powder that has built a loyal following as a daily water flavoring, sold in canisters and stickpacks at Target, Walmart, Whole Foods and on Amazon. One scoop or stick in 16 oz of water supplies 250 mg potassium, 100 mg magnesium, 47 mg calcium, 70 mg phosphorus, 78 mg chloride and just 55 mg sodium, plus 100 mg vitamin C and small amounts of zinc and manganese, sweetened with organic stevia.

That profile is the key thing to understand. Sodium is the main electrolyte lost in sweat, and the American College of Sports Medicine notes that sweat rates and sweat electrolyte content vary considerably between people; 55 mg is a fraction of the 300-1,000 mg found in typical sport and high-sodium mixes, and far below oral rehydration solutions. Ultima is therefore better thought of as a mineral-enhanced, sugar-free flavored water than as a rehydration product for long workouts, heat or illness. For people who want to drink more water, avoid sugar and keep sodium low, that is a genuine advantage.

The label is fully disclosed and short on additives: no sugar, no artificial sweeteners and plant-based flavors and colors. Ultima states its mixes are Non-GMO Project Verified, vegan and gluten-free, with regular gluten testing, though it does not advertise third-party contaminant or sport certification.

buyers love the taste and the lack of sugar, and many say it eases muscle cramps and headaches and makes hydrating easier, while some report that it does not always dissolve smoothly. The 90-serving canister works out to about $0.53 a serving, making it one of the cheapest options here for everyday use.
