Formulation Notes

Branched-chain amino acids with L-Glutamine, Zinc, B-6 & B-12

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.

Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, starch, preservatives, or artificial color, flavor or fragrance.

Additional Information
