RAPID REHYDRATION & RECOVERY - electrolytes powder hydration drink created by experts in sports science and nutrition. It can be taken pre workout, intra workout or after exercise to boost energy and replace liquid lost through sweat. Avoid post workout fatigue, sore muscles and muscle cramps, experience rapid revival and recovery by replacing minerals and salts you lose through sweat - whether you are a runner, cyclist, sports, fitness or gym enthusiast
SODIUM, POTASSIUM, MAGNESIUM minerals - isotonic drink formula based on decades of research science in sport and nutrition, Mr Run’s electrolytes drink contains purest forms of electrolyte salts and trace minerals sourced from high up Himalayan mountains. It can be used alongside running gels and carbohydrates - simply add a scoop or two to your running water bottle and go
ZERO SUGAR or CALORIES - compared to other isotonic sports drinks, energy drink powders, energy gels, hydration tablets, energy tablet and electrolytes sachets, our electrolytes drinks powder is gluten free, contains zero sugar, carbs or calories and is without artificial additives. We use only the pure minerals like sodium, potassium citrate and magnesium glycinate with a refreshing natural raspberry flavour
