Sustained plus Immediate Release L-Arginine contains this conditionally 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 allows for enhanced blood levels of this nutrient. Most supplemental L-arginine is quickly absorbed into circulation and is extremely efficiently metabolized, yielding only a short-lived boost to L-arginine levels. 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 vigorous 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.

Posted by iHerb Customer on May 14, 2017 | Verified Purchase

I have tried various supplements to lower blood pressure as the traditional pharmaceuticals really do not lower blood pressure and have side affects. So this really does work when taken as directed

Thanks for your feedback!
