I second this. Because it keeps forever and is relatively small, I keep it around in the medicine cabinet. If you've ever had a guest lose a fight with a Norovirus, you appreciate having some of it right at hand.

By the way, the Amazon product searches for this return a cesspool of magic woo. I recommend going to your local drug store, looking for the powdered Pedialyte, then looking in the meter-or-so surrounding that area for the cheaper store-brand version.

Then again sugar and salt also keep forever. I guess the sealed unidoses help though.

The trick is to search for "WHO" oral rehydration salts.

Coconut water is marketed for hydration because it does have a relatively high electrolyte content, but it's mostly potassium with minimal sodium, so not as effective as an oral rehydration powder which has those specific ratios of electrolytes / sugar that maximize the speed of uptake/hydration.
