Amino Complex is NSF Certified for Sport®. It supports sports-related, fitness-related, and training-related activities, and it promotes the increase of muscle mass for someone needing that benefit, including the elderly*. Amino acid supplementation can decrease fat synthesis, improve redox status, and promote energy production via activation of NRF-2 and PGC-1alpha.* Amino acids also promote mitochondrial biogenesis – the body's internal production of energy.* The comprehensive blend of essential amino acids in Amino Complex is high in branched-chain amino acids, a group of amino acids that have been validated through numerous clinical trials to promote the growth of lean muscle mass and enhance muscle strength.* This active ingredient formulation in Amino Complex is backed by more than 25 years of scientific and clinical research. Amino Complex comes in two flavors, lemon and berry, and is lightly sweetened. It mixes easily with warm or cold liquids, has no artificial sweeteners, and contains flavors only derived from natural sources.
