Now, Double Strength 1000 mg L-Arginine Supplement Tablets include 1g L-Arginine to support optimal absorption and assimilation. L-arginine is a conditionally necessary basic amino acid that has a role in urea metabolism and excretion, as well as DNA synthesis. It is a key precursor of nitric oxide (NO), which contributes to blood vessel dilatation. Arginine dietary supplement enhances the effects of exercise and is engaged in a variety of critical pathways throughout the body. L-Arginine may boost exercise performance by increasing nitric oxide levels in the body, which enhances blood flow and oxygen delivery to muscles. It relaxes the cells that make up blood arteries while also regulating blood pressure. This product has twice as much L-arginine (1,000 mg each pill) as the brand's standard strength offering (500 mg per capsule).
