Introducing Doctor's Best L-Arginine - Sustained + Immediate Release, a powerful dietary supplement designed to support your cardiovascular system and enhance circulation. Each serving provides a total of 1000mg of L-arginine in a unique bilayer tablet format. By combining both 500 mg of immediate-release and 500 mg of sustained-release L-arginine, this formula helps maintain elevated blood levels of L-arginine for up to 8 hours.

How It Works

Clinical studies have illustrated the benefits of oral L-arginine supplementation for cardiovascular health. Research indicates that it promotes increased blood flow and can enhance heart function when compared to a placebo. L-arginine is a key player in nitric oxide (NO) production, a vital component in vascular health that can lead to improved exercise performance and endurance.

Why You Should Choose Sustained + Immediate Release L-Arginine

As we age, our bodies may produce less nitric oxide, which is essential for healthy vascular function. This decline can contribute to reduced endothelial function, highlighting the importance of L-arginine dietary supplementation. By incorporating this formula into your daily routine, you can actively support cardiovascular function and combat some age-related challenges. Additionally, it offers antioxidant benefits which help neutralize free radicals, further protecting your cardiovascular health.
