A few months ago C+ mentioned in their new products section a liquid you can add to water to make it isotonic. It doesn't contain the sugar, caffeine, etc. of energy drinks, just the salts required to make water isotonic. Anyone know what it's called?
It wasn't but Nuun seems to be the same thing. Thanks.
The stuff I saw was a small bottle of clear liquid. You only add a few drops per litre of water and it was not flavoured at all (maybe a bad thing). These Nuun tabs look quite good. I'll give 'em a try.
