  • Science-based nutrition

  • Promotes a healthy cardiovascular system

  • Enhances healthy circulation
Sustained plus Immediate Release L-Arginine from Doctor's Best delivers the amino acid in a bilayer tablet, with two tablets providing 500 mg of sustained release and 500 mg of immediate release L-arginine. This formula allows for enhanced blood levels of this nutrient. Sustained plus Immediate Release L-Arginine 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. L-arginine has been shown to support the cardiovascular system, promote heart function and enhance healthy circulation throughout the body through its conversion to nitric oxide. Research suggests L-arginine supplementation may also have positive benefits on athletic performance.

L-Arginine Sustained plus Immediate Release 4.8 5 3 4
Excellent product. The immediate release plus sustained feature is most welcome. I take 2 per day with very good results. April 17, 2013
Wonderful Can definitely tell a difference in my stamina when taking. March 14, 2013
my body must have been starved for this The first few times taking this product I definitely felt better (more alert, cleaner at a cellular level). But, after the first few times, I really don't notice anything anymore. Perhaps the deficiency was satisifed? Perhaps I need to increase the dosage? February 10, 2013
