Branched-Chain Amino Acids with L-Glutamine, Zinc, B-6 & B-12
Formula re: Contains
Source Naturals BCAA provides support to your body's muscular systems with a vigorous blend of branched-chain amino acids and supporting B vitamins. Research has shown that during exercise, branched-chain amino acids are metabolized directly in the skeletal muscle-a process that provides robust musculoskeletal fortification when your body needs it the most. Combined with vitamin B-6 and B-12 for optimized protein synthesis, BCAA may also increase energy and reduce occasional fatigue in support of your active lifestyle.
Formulation re: Does NOT Contain
Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, starch, preservatives, or artificial color, flavor or fragrance.
