Sports nutrition support; Muscle protein support; Workout recovery
Active adults who train regularly and people with lower dietary intake of high-protein foods.
Take 2 capsules once daily with a meal; taking amino acids with food may improve tolerance.
Leucine activates mTOR signaling in muscle, which may promote muscle protein building and reduce muscle breakdown after exercise.
Caution: High-dose amino acids on an empty stomach may cause stomach discomfort; take with food as directed.
Isoleucine participates in muscle protein turnover and may support energy use in muscle during activity.
Caution: Those monitoring protein or amino acid intake should account for isoleucine from all sources to avoid excessive intake.
Valine is used by muscles as a building block and may help buffer muscle protein breakdown during physical stress.
Caution: May compete with other large neutral amino acids for transport; take as directed and avoid combining with high-dose standalone amino acids unless guided by a professional.
Leucine serves as the primary signal for muscle protein building, while isoleucine and valine provide additional branched-chain substrates that participate in muscle metabolism. Together in a 2:1:1 ratio, they offer a balanced intake that targets signaling and structural needs for active muscles.
Label Warning: Consult a physician before use if taking any medications or under medical care. Not for those under 18 years old. Not for women who are pregnant, trying to become pregnant, or nursing.

The Power of Branched Chain Amino Acids
L-Leucine, L-Isoleucine and L-Valine are commonly grouped together and referred to as Branched Chain Amino Acids, or BCAAs, because of their unique branched chemical structure. BCAAs are essential, meaning they must be consumed through the diet since the human body cannot make them from other compounds. One 2-capsule serving provides 1000 mg of BCAAs.
