NOW Foods L-Arginine 500 mg 100 Veg Capsules

Support healthy circulation, exercise performance, and overall wellness with NOW Foods L-Arginine 500 mg, a premium-quality amino acid supplement manufactured by NOW Foods USA.

L-Arginine is a conditionally essential amino acid that plays an important role in protein synthesis, urea metabolism, and nitric oxide (NO) production. Nitric oxide helps relax blood vessels, supporting healthy blood flow and nutrient delivery throughout the body. This makes L-Arginine a popular supplement among athletes and active individuals looking to support workout performance and muscle recovery.*

Each serving provides 1,000 mg of free-form pharmaceutical-grade L-Arginine (500 mg per capsule). The formula is suitable for vegetarians and vegans and is manufactured in a GMP-certified facility. It is Non-GMO, Halal, Kosher, and produced without wheat, gluten, soy, milk, eggs, fish, shellfish, or tree nuts. Natural color variation may occur due to the nature of the ingredients.
