Doctor’s Best BCAA (Branched Chain Amino Acids) Powder stimulates muscle growth, prevents muscle breakdown, helps prevent exercise-induced fatigue and increases preferential loss of body fat.*
BCAA provides the branched chain amino acids – leucine, isoleucine and valine, essential nutrients that the body cannot produce and must be acquired by diet or supplementation.
Athletes use BCAAs to improve exercise performance and reduce protein and muscle breakdown during intense exercise.*
This Doctor’s Best item contains no added colors, flavors, fillers, additives or unnecessary ingredients.

Doctor’s Best BCAA Powder stimulates muscle growth, prevents muscle breakdown, helps prevent exercise-induced fatigue and increases preferential loss of body fat.* Doctor’s Best BCAA Powder provides the branched chain amino acids – leucine, isoleucine and valine that are essential nutrients that the body cannot produce itself and must be acquired by diet or supplementation. Athletes use BCAAs to improve exercise performance and reduce protein and muscle breakdown during intense exercise.* This Doctor’s Best item contains no added colors, flavors, fillers, additives or unnecessary ingredients.
The primary mechanism through which BCAAs stimulate muscle growth is by activating the protein mTOR. The mTOR signaling pathway is responsible for muscle protein synthesis. Muscle protein synthesis stimulated by the mTOR protein enhances muscle repair and hypertrophy. Another mechanism by which BCAAs can increase muscle mass is by attenuating muscle breakdown as a result of exercise. Muscle breakdown has been shown to be suppressed with BCAA supplementation.*
BCAAs are vital for muscle protein synthesis. BCAAs act as constituent proteins for the building of muscles and their presence activates signaling pathways for muscle growth. Supplementation with BCAAs prevents fatigue during exercise by attenuating the decline of circulating levels of BCAAs.* Supplementation has also been shown to improve athletic performance during both strength and endurance exercises in addition to increasing preferential loss of body fat.*
