NOW Foods L-Arginine Powder 2.2 lbs.

NOW® L-Arginine Powder supplies pure, free-form L-arginine in a convenient, easy-mixing powder that lets you customize your serving size. Arginine is a conditionally essential amino acid with two especially notable roles: it participates in the urea cycle (the body's system for clearing nitrogen) and it serves as the direct precursor to nitric oxide, a molecule that helps blood vessels relax and supports healthy circulation. Through these functions, arginine supports protein metabolism, healthy muscle tissue and cardiovascular wellness, which is why it's a staple among athletes and active adults.*

About the key ingredients

• L-Arginine (free-form): A conditionally essential amino acid and direct nitric-oxide precursor that supports protein metabolism, muscle maintenance and healthy circulation.*
• Other ingredients: Pure amino-acid powder with no 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

Mix 2 level teaspoons daily as needed in at least 8 oz. of juice or water, preferably on an empty stomach. Store in a cool, dry, dark place after opening.
