Life Extension L-Arginine Caps, 700 mg, 200 Capsules

Life Extension's L-Arginine Caps provide 700 mg of L-arginine per capsule, formulated to support arterial health and cardiovascular function. Each serving includes 10 mg of vitamin C as ascorbyl palmitate, which the manufacturer notes is added to enhance the supplement's benefits. The product is intended to help maintain healthy tissue and bones, support already-healthy blood pressure levels, and contribute to immune system health, based on its role as a precursor to nitric oxide.

This supplement is designed for daily use, with one capsule taken on an empty stomach. The manufacturer references several clinical studies in their overview, linking L-arginine to nitric oxide production and vascular health. Life Extension emphasizes over 40 years of research in developing scientifically-validated formulations. The capsules are vegetarian, using vegetable cellulose shells, and are certified gluten-free and non-GMO.
