If you're an athlete, I'd recommend LMNT. It's easy to make yourself, tastes great, and easy on the stomach. Here's my recipe (all bought in bulk in a very fine powder form - they need to be consistent particle sizes so they mix well) which should be fairly close to LMNT, although a chemist will probably tell me I'm wrong: 20g magnesium malate 20g potassium chloride 142g salt 140g citric acid 15g stevia powder (pure, not mixed with some other sweetener) 20g artificial flavoring powder (not affiliated, but I have used black cherry powder from naturesflavors.com with good success) Mix it up and then put 1 tsp in 20-32oz water. Should last you a long while.
