Sustained plus Immediate Release L-Arginine contains this conditionally essential amino acid in a bilayer tablet, with 2 tablets providing 500 mg of sustained release and 500 mg of immediate release L-arginine in a formula that promotes 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 help immediately increase blood levels of L-arginine and then to help 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 help enhance healthy circulation through it's conversion to nitric oxide.*  Research suggests L-arginine supplementation may also promote positive benefits on athletic performance.*
