When elete was filling my request for samples for my clinic they asked what I needed. I told them I can always use the original elete since I use it all day every day. I expected one of the 8 oz bottles...instead I got this giant bottle. Guess what? I'll use it too. That's the great part. I rely on these electrolytes every day. I sweat 1-3 hours every day and even more on the weekends. There is no way to keep up on all the loss of electrolytes through diet alone, so I drink this stuff (a few drops diluted in 24 oz) and it keeps me feeling great!
