There are so many better options now than 1970's era "liquid candy" Gatorade that's full of sugar (34 grams per serving, that's more than an ounce of sugar!). Yes, there's sodium and potassium, but no magnesium which is quite important for muscle contraction (avoiding cramps) and is often lacking in hiker diets.

Be careful because Gatorade will rot your teeth like nothing else.

So we use S-caps, developed for ultra runners. We have found them to quickly relieve cramps during long hard endurance events.

We also use Tru-hydrate powder in our flasks in hot weather, and Mg complex powder by Gobiotix. Both have a pleasing flavor.
