NOW Foods L-Arginine, 500 mg, 100 Veg Capsules

NOW Foods L-Arginine 500 mg Veg Capsules is a free-form amino acid supplement designed to support nitric oxide production and vascular function. Each serving of two capsules provides 1,000 mg of L-arginine, a conditionally essential amino acid that the manufacturer notes is involved in urea metabolism, DNA synthesis, and protein production. The product is intended for use between meals or at bedtime to facilitate absorption.

This supplement uses pharmaceutical-grade L-arginine, which the manufacturer highlights as a quality distinction. It is formulated with vegan-friendly ingredients, including hypromellose cellulose capsules and vegetable-sourced stearic acid, and is available in a 100-count bottle with 50 servings. Certifications include Non-GMO, Vegan, Kosher (Triangle K), and Intertek GMP Supplement Certification, reflecting its manufacturing standards. A 250-capsule size is also offered for those seeking a larger supply.
