NOW L-Arginine 1000 mg is an amino acid supplement primarily used to increase nitric oxide production in the body. Nitric oxide helps relax and widen blood vessels (vasodilation), which improves overall circulation and blood flow.
Primary Benefits
- Circulatory Support: By relaxing blood vessels, it helps maintain healthy blood pressure levels and supports general cardiovascular health.
- Exercise Performance: Athletes often use it to improve "the pump" during workouts. Better blood flow means more oxygen and nutrients reach the muscles, which can help with endurance and recovery.
- Sexual Health: Because it improves blood flow throughout the body, it is sometimes used to support erectile function and reproductive health.
- Immune & Healing: It plays a role in cell division and protein synthesis, which can help the body recover from injuries or surgery.
- Blood Pressure Interactions: Use caution if you already take blood pressure medication or nitrates (like nitroglycerin), as the combination could cause your blood pressure to drop too low.
Usage and Safety
- Standard Dose: 1000 mg is a common serving size. For athletic performance, it’s often taken 30–60 minutes before a workout.

Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion, as well as in DNA synthesis and protein production.* It is an important precursor of nitric oxide (NO) and thus plays a role in the dilation of blood vessels.*
