I know these are articles from sites for commercial electrolyte products, but after seeing what Bill has gone through I'm a firm believer in needing more than salt. Back in the "olden" days, we were always told to eat foods such as bananas because they are high in potassium.

Bill has been suffering now for a couple years with severe cramping even though he was using Cytomax and e-Caps. Elete Water has seemed to fix the problem and he has been just flying this summer. It has a much higher dose of potassium than other products.
