There are alot of supplements out there on the market, and sometimes it can be overwhelming. For the last 3 years I have only taken Advocare products. The best athletes in the world such as Rich Froning take them because they are effective and banned substance free for EVERY level of sport. The products are studied and formulated by Advocare's Sci/Med board full of Doctors with over 200 years of experience in the field of Sports Medicine. Supplements are just one part of the equation, but are essential for recovery and performance during intense exercise.
