I agree with you about the sports drinks HC, only their biggest problem, as I'm sure you're aware, is the electrolyte balance is off. They're way heavy on the sodium and practically nil on the potassium. Considering that Americans typically average double the RDA of sodium per day (which is over 3K mg.) folks should at least be aware of the great amounts of sodium they're taking in when consuming these drinks.
Recently I performed an extensive search on the internet for a sports drink with adequate amounts of potassium. I found none.
