Electrolyte SR 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, Electrolyte SR can help you maintain peak performance during your activity and recover fast for your next challenge.* 

Electrolyte SR 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 Electrolyte SR before your activity to help maintain fluid balance, or take after your activity to rehydrate fast. Simply drink plenty of water according to thirst.*
