Enervit PURE-PRO Electrolytes Boost Fuel Your Performance with Pure Precision. Enervit PURE-PRO Electrolytes Boost delivers precisely what active athletes need: essential electrolyte replacement without unnecessary calories or sugar. This innovative formula targets optimal hydration by containing chloride salts in the form of sodium and magnesium salts, specifically designed for those who engage in intense and prolonged physical activity. Science-Based Formulation Each sachet provides 400 mg of sodium and 56 mg of magnesium, addressing the fundamental fact that sodium is the most abundant salt lost through sweat. Magnesium contributes to electrolyte balance, helps reduce fatigue, and supports normal muscle function, making this dual-mineral approach ideal for sustained performance. Clean Performance Nutrition At only 2 calories per sachet with zero sugars, this formula eliminates blood sugar fluctuations that can compromise training. Naturally flavored and sweetened with steviol glycosides from stevia, it provides clean hydration support throughout your active day. We're a huge fan of electrolyte supplements with no sugars and minimal calories – we use them as everyday hydrators.
