Salt tablets. Surprised? There is almost no loss of potassium in sweat, but huge losses of salt. Salt tablets and regular foods restore electrolytes in the field...for me. Damn near free and easy to use and carry.
Isn't that what Mountain House is for, while in the field?
Liquid IV. Works great and way less sugar than Gatorade.
I have really liked using Nuun tablets. Easy to carry and lots of flavors. There are even some with caffeineCurious what everyone is using for electrolyte replenishment on backpacking trips? Powders, tablets, chews etc? Looking for something healthy, light and fast for cramp prevention.
