Surprisingly, Gatorade lists the RDA's of Sodium and Potassium. The RDA for Sodium turns out to be the equivalent of about 2.5 gpd (grams per day), while Potassium is higher, at about 3 gpd.

Dietary studies have shown that most adult Americans are deficient in Potassium. I remedy that by using salt substitute, which is Potassium Chloride instead of regular table salt.

I believe the potassium content is higher in sea salt, too, but you have given me an idea.

I'm going to put some salt substitute in with my field gear, just for next time.

If that never happens, well it'll still be a million years too soon!
