What is Doctor's Best Sustained Plus Immediate Release Arginine? Doctor's Best Sustained Plus Immediate Release Arginine promotes a healthy cardiovascular system, improves healthy blood flow and supports heart function. L-arginine has been shown to support the cardiovascular system through its conversion to nitric oxide. Studies show that L-arginine supplementation may also have a positive effect on athletic performance. Two tablets of Doctor's Best Sustained Plus Immediate Release Arginine provide 1000 mg of L-arginine per bilayer tablet, while two tablets provide 500 mg of sustained release and 500 mg of immediate release L-arginine. This technology allows for increased L-arginine levels in the blood continuously for up to 8 hours. How does it work? Oral L-arginine supplementation has been shown in clinical studies to support various aspects of cardiovascular health. A randomized, double-blind, placebo-controlled trial showed that six weeks of L-arginine supplementation improved blood flow and supported healthy heart function compared to placebo. The effects of L-arginine were due to its role in NO production. Other clinical studies have shown that oral L-arginine supplementation contributes to improved exercise tolerance due to its ability to improve cardiac blood flow and vasodilation. Dietary L-arginine supplementation in healthy subjects has been shown to maintain blood pressure, already at normal levels. The combined results of these and other clinical studies have shown that long-term use of this amino acid significantly improved endothelial function. Why take Sustained and Immediate Release Arginine? The normal aging process in humans has been shown to be associated with progressive changes in endothelial function (the cells that line the inner surfaces of blood vessels). Studies suggest that the primary cause of these common age-related changes is reduced production or bioavailability of nitric oxide (NO) in blood vessels and tissues. L-arginine is a substrate for the enzyme nitric oxide synthase, which is required for the production of nitric oxide in the body. Nitric oxide is a substance that is critical for maintaining normal vascular function. NO regulates many physiological effects on the cardiovascular system, including maintaining healthy endothelial function, improving cardiovascular health, and demonstrating potent antioxidant properties against free radicals.
