About this item
Product details
Doctor’s Best Sustained plus Immediate Release L-Arginine contains this essential amino acid in a bilayer tablet, with two tablets providing 500 mg of sustained release and 500 mg of immediate release L-arginine in a formula that delivers enhanced blood levels. These tablets are specifically manufactured to immediately increase blood levels of L-arginine and then to sustain this beneficial increase continuously over an 8-hour period.* Research suggests that arginine supplementation helps increase muscle mass and may also positively beneficial in improving endurance as it is a precursor to creatine, which helps supply energy to all cells of the body.* L-arginine has been shown to support the cardiovascular system, heart function and improve overall circulation through its conversion to nitric oxide.* At Doctor’s Best, we lead with science. Our products are backed by research and crafted using pure ingredients carefully sourced from around the globe. Since 1990, we have dedicated ourselves to providing highly effective nutritional supplements that enable you to live a healthier lifestyle. We want nothing more than to see you and your family thrive!

Dr. Recommended
I started taking this on the advice from my doctor to take 500 mg twice daily to aid with the circulation into my hands. It does seem to be helping…plus it apparently also helps with exercise, which is a bonus. I chose this one for it's sustained release and I trust Dictor's Best as a brand overall.

Great Product!!
I believe this product really helps in increasing my nitric oxide levels. I love that it's a sustained released product, which helps to keep my nitric oxides levels up longer between doses.
