Why Did They Add Collagen to Amino Energy?

Amino Energy is one of our hottest selling products and is used for both a Pre Workout by some, and an Amino Acid formula by others. By adding 10mg of undenatured Type II Collagen, the aim is to support healthy joints. They've also added Vitamin C which also supports collagen synthesis and provides antioxidant support. 


2 scoops in 10-12 fluid ounces of cold water makes one serving of AMIN.O. ENERGY PLUS UC-II COLLAGEN, but you can dial-it-up by adding more!
