This supplement contains a synergistic combination of L-Arginine and L-Citrulline, essential amino acids that support nitric oxide production in the body. L-Arginine plays a key role in the urea cycle and is a precursor to nitric oxide, which helps promote healthy blood flow. L-Citrulline is readily converted into L-Arginine, maximizing its bioavailability. These vegetarian capsules are formulated to support cardiovascular health and can be beneficial for active individuals looking to enhance exercise performance through improved circulation.
