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.
