I'm a little late coming to this - but there is an electrolyte mix made by Alcer which is available from most health food stores. It has no sugar, sweetners, etc etc so I can tolerate it. (I can't have any sugars/glutens!) It has a lemon-limey taste - very subtle and mixes with water so you can put it in your water bottle and/or drink it after you ride. What is does have is calcium, potassium, magnesium, manganese, boron, and - oh darn it - I forget the other ingredient. Most OTC sports drinks made me very sick to my stomache before I found out why. Hoping this will help.
