Twinlab L-Arginine -- 500 mg - 100 Capsules

Easier to Swallow and Assimilate. Gluten Free. L-arginine is a free-form amino acid that is needed to create both creatine and urea a waste product that is necessary for the removal of toxic ammonia from the body. While the body typically manufactures enough l-arginine it is considered a semi-essential amino acid as supplementation is sometimes needed. Arginine is a precursor to nitric oxide which causes relaxation of the blood vessels and also plays a key role in the production of protein.
