NOW Foods L-Arginine 500 mg – 250 Veg Capsules

NOW Foods L-Arginine 500 mg is a pharmaceutical-grade amino acid supplement formulated to support nitric oxide production, normal vascular function, and protein metabolism. Each vegetarian capsule supplies 500 mg of free-form L-Arginine, while the two-capsule serving provides 1,000 mg. L-Arginine is a conditionally essential amino acid involved in several important biological processes, including urea metabolism, protein production, and DNA synthesis. It also serves as a precursor to nitric oxide, a naturally produced compound that helps maintain normal blood vessel relaxation and healthy circulation. This makes L-Arginine a practical addition to active lifestyle and general wellness routines. Each bottle contains 250 vegetarian capsules, providing 125 servings. The flexible 500 mg capsule strength makes it easy to follow the label’s divided daily directions. This formula is vegan, non-GMO, halal, kosher, soy-free, nut-free, dairy-free, egg-free, and made without gluten.
