NOW Foods L-Arginine 500mg 250 Veg Capsules

NOW® L-Arginine supplies 500 mg of free-form L-arginine in each veg capsule. Arginine is a conditionally essential amino acid that plays two important roles in the body: it takes part in the urea cycle that clears nitrogen, and it is the direct precursor to nitric oxide — a signaling molecule that helps blood vessels relax and supports healthy blood flow. Through these pathways, arginine supports protein metabolism, the maintenance of healthy muscle tissue, and cardiovascular wellness, making it a longtime favorite among athletes and active adults.*

About the key ingredients

• L-Arginine (free-form) – 500 mg: A conditionally essential amino acid and nitric-oxide precursor that supports protein metabolism, muscle maintenance and healthy circulation.*
• Other ingredients: Cellulose in a plant-based hypromellose (vegetarian) capsule, with no artificial fillers.

Who it's for

NOW® L-Arginine suits athletes, weight trainers and active adults who want to support healthy circulation, blood flow to working muscles and protein metabolism as part of an active lifestyle. It's also chosen by those interested in cardiovascular wellness and in supporting the body's nitric-oxide pathway, which naturally becomes less efficient with age. Whether you prefer capsules, tablets or an adjustable powder, it's typically taken away from food, and often before workouts, for the best absorption and effect.*

Suggested use

Take 2 capsules twice daily as needed. Take between meals or at bedtime with at least 8 oz. of water or juice to facilitate absorption. Store in a cool, dry place after opening.

As with any supplement, talk to your doctor before adding this product to your routine if you are pregnant or nursing, taking prescription medication, or managing a health condition.
