High efficiency protein source Fortified with all essential and branched chain amino acids

Essential Amino Protein starts with an ultra-high quality, easy-to-digest protein source focused on the essential and branched chain amino acids in the form of easy-to-absorb smaller peptides and free-form amino acids. Typical protein sources and powders can contain difficult-to-digest and absorb proteins, but Essential Amino Protein starts with a highly bioavailable protein source that we fortify with essential and branched chain amino acids. Essential Amino Protein is not just an advanced protein source for athletes, but also provides the most important amino acids for anyone focused on wellness and optimum health. Essential Amino Protein provides an ideal balance of amino acids to support the structure and function of our key organs and tissues, along with the enzymes we rely upon to perform all our body’s biochemical and metabolic activities. It is well established that protein quality more than the quantity determines optimum health and physical performance, which is why Essential Amino Protein focuses on those amino acids that determine protein quality. Essential Amino Protein comes in small easy-to-swallow capsules that contain our highly bioavailable protein/amino acid source, which is also hormone-free, lactose-free and sodium-free.
