ReplaceSR Sustained Release Electrolyte is a balanced combination of electrolytes designed for adults (and teens) who engage in vigorous, prolonged physical activity, especially in a hot climate. Whether your active lifestyle is for work, play or sports, ReplaceSR can help you maintain peak performance during your activity and recover fast for your next challenge.* ReplaceSR uses an advanced delivery technology to release electrolytes slowly over a 4-to-6 hour period as your body needs them to absorb the fluids you drink. Take ReplaceSR before your activity to help maintain fluid balance or take after your activity to rehydrate fast. Simply drink plenty of water according to thirst.* ReplaceSR is available in two sizes (trial and competition) and is free of sugar, starch, artifical ingredients, and common allergens (milk, egg, fish, shellfish, tree nuts, peanuts, wheat and soy).
