The Active Ingredient Is: L-Leucine (Leucine)

Leucine is an essential branched-chain amino acid found in dietary protein and supportively involved in muscle metabolic processes. This form refers to the single amino acid leucine, a key component of BCAA blends used to support daily exercise goals.

Leucine is naturally present in protein sources and participates in muscle protein turnover, contributing to the body’s normal muscle maintenance during and after activity.

What Does L-Leucine Do?

Leucine is involved in stimulating muscle protein synthesis and supporting muscle maintenance during training. It also assists with reducing muscle protein breakdown and may help with glycogen preservation during exercise, contributing to recovery and energy management.

Dr. Norton of Harvard University found that leucine directly stimulates muscle protein synthesis after exercise, aligning with its role in supporting post-exercise recovery.
