This is a significant benefit when considering how heavy water is to carry and was revealed in a peer review published study using forest fire fighters in California. The study was conducted in the summer of 2008 by The University of Montana, in which 8 forest fire fighters were given water with elete added and 8 were given plain water over a period of five days of intense forest fire fighting. The results were astounding; those with elete in their water on average consumed 42.6% less fluid........... to stay equally hydrated! Or to put it another way, those firefighters who drank plain water consumed 74 percent more water to achieve the same level of hydration as those who consumed water with elete Electrolyte Add-In
