My son has been using this for years for half his liquid drinking (sometimes all, in very hot weather), during his tennis matches. In 5+ years of playing competitive tennis, he's only cramped once (failed to pre-hydrate in previous day's practices).

I have been ride a road bike for a year. now that EFS is on my ride 65 mile come a lot easier with little to no cramping. Also at work in the warehouse its hot at the top when on the cherry picker like 110* to 120* when at 40 ' up. I was light headed and with headaches did not know I was dehydrating so fast, EFS is now in my locker at work to help on those hot days it works great :)
