NOW Foods Arginine & Citrulline Powder 12 oz.

NOW® Arginine & Citrulline Powder brings together two complementary amino acids in a convenient, mixable powder. L-arginine is the direct precursor to nitric oxide, while L-citrulline is an amino acid the body efficiently converts into arginine — so taking them together helps sustain arginine levels and support the nitric-oxide pathway more effectively than arginine alone. Together they support protein metabolism, healthy muscle tissue and circulation, which makes this powder a popular pre-workout choice for athletes and active adults.*

About the key ingredients

• L-Arginine & L-Citrulline: Complementary amino acids that support protein metabolism and the body's nitric-oxide pathway; citrulline helps sustain arginine levels for longer-lasting support.*
• Other ingredients: Pure amino-acid powder.

Who it's for

NOW® Arginine & Citrulline is a natural fit for athletes, weight trainers and active adults who want longer-lasting nitric-oxide and circulation support around their workouts. Because citrulline helps sustain arginine levels, it also appeals to those who found plain arginine short-lived, as well as anyone looking to support healthy blood flow, nutrient delivery to muscles and exercise performance. Many users take it before training and, in the powder form, appreciate being able to adjust the serving to their goals.*

Suggested use

Mix 1 level teaspoon twice daily as needed in 8 oz. of water or other beverage, preferably on an empty stomach. Store in a cool, dry, dark place after opening.

Cautions & interactions

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. Keep it out of reach of children, store it in a cool, dry place, and don't exceed the recommended serving. Amino acids that support the nitric-oxide pathway may affect circulation, so if you take medication for blood pressure or are scheduled for surgery, check with your doctor before using arginine-based products, and avoid combining several nitric-oxide supplements at once without guidance.
