I like that Klean Multivitamins don't make me burp! It's a first. TMI? Also, I have found that loading both water bottles with common hydration powder (with lots of sugar and electrolytes) was a really bad idea in hot and dry conditions like Arizona. My mouth ended feeling dry like cement. I really like the Klean Athlete Endurance and Electrolytes so I can have at least one bottle of pure water on my bike.-Beatrice Dormoy, Klean Team USA Cyclist
Not sure if its the Endurance but since taking it my run splits have been great. Negative splits and extra energy at the END of my run. I'm going to keep taking them (and they taste great too)!-Kevin Baker, Multisport Athlete
