EndurElite has done it again with another fantastic product! I was a beta-tester for Hydrate and I used it before, during, and after exercise with zero issues. Heck I even sipped on it all day because of the taste and it's ability to quench my thirst. I don't know about you put I have a hard time drinking enough water. Add a scoop of Hydrate to water and you'll be drinking it all day. Did I mention I felt more hydrated during exercise and had zero issues with cramping. This may be my favorite EndurElite product to date but who am I kidding......they are all my favorite!
