Doctor's Best Sustained Plus Immediate Release Arginine is a premium dietary supplement designed to support cardiovascular health and enhance athletic performance. This unique formulation combines both sustained and immediate release of L-arginine, delivering a total of 1000mg per serving. L-arginine is an essential amino acid that plays a crucial role in the production of nitric oxide (NO), a compound that helps to relax and dilate blood vessels, thereby improving circulation and supporting heart function. With its advanced bilayer tablet technology, this product ensures that L-arginine is released into the bloodstream over an extended period, providing benefits for up to 8 hours. The importance of L-arginine in maintaining cardiovascular health cannot be overstated. Clinical studies have shown that supplementation with L-arginine can enhance circulation, support healthy heart function, and improve exercise tolerance. As we age, our bodies may produce less nitric oxide, leading to diminished endothelial function and cardiovascular health. By incorporating Doctor's Best Sustained Plus Immediate Release Arginine into your daily routine, you can help counteract these effects and promote a healthier vascular system. This supplement is ideal for individuals looking to improve their cardiovascular health, athletes seeking to enhance their performance, and anyone interested in maintaining optimal blood flow and circulation. With its scientifically-backed formulation, Doctor's Best Sustained Plus Immediate Release Arginine is a valuable addition to any health regimen, providing the support your body needs to thrive.
