The Active Ingredient Is: L-Arginine

L-Arginine is an amino acid involved in everyday protein metabolism and energy production for active individuals.

This form is provided as a free-form amino acid for absorption, along with L-ornithine to support metabolic processes during exercise.

What Does L-Arginine Do?

L-Arginine helps to support nitric oxide production, which promotes vascular dilation and blood flow during physical activity. It also plays a role in energy metabolism and recovery in the context of intense training.

Scientific research suggests these functions contribute to normal exercise performance and metabolic responses. This information aligns with EFSA-endorsed understanding of amino acids in relation to normal vascular and energy processes.
