TWINLAB: L-Arginine 500mg, 100 cp

L-arginine is a free-form amino acid that is needed to generate both creatine and urea, a waste product that is necessary for the removal of 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.

Each capsule contains 500 mg of L-arginine. Well tolerated by the most highly allergic individuals, the Twinlab L-arginine capsules contain no tablet binders, coatings or added flavorings, salt, artificial sweeteners, colorings, preservatives or salicylates.
