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 cardio- vascular 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.Promotes a Healthy Cardiovascular System, Enhances Healthy Circulation and Supports Heart FunctionThe normal aging process in humans has been found to be associated with progressive changes in endothelial function (cells that line the inner surfaces of blood vessels). Research suggests that a major reason for these common changes associated with aging is reduced production or bioavailability of nitric oxide (NO) in vessels and tissues. L-arginine is a substrate for the enzyme nitric oxide synthase, required for the production of nitric oxide in

Best Time Released L-Arginine I've Found
I was happy to find that this has both immediate release and time released components and I only have to take two at a time (I was taking 3 with another brand) twice a day. I was able to reduce my prescription HBP drug dosage by half by taking it. I'm happy.

Great recovery tool
I take this with 2 or 3g curcumin after streneous activities that would otherwise have me painfully sore for days. I'm good to go after 8 hours of sleep!

A hard pill to swallow
Firstly, these pills are VERY hard to swallow, they're large but not huge, it's their rough surface that is the problem.Secondly, they don't seem to do anything! When i take arginine i notice a benefit within a few hours.With these there's no noticable benefit.I don't recommend these.

Take Pine Tree Bark & L-Arginine together
L-Arginine does not actively stay in the body for more than a couple of hours... so I feel the sustained is the best way to go to increase nitric oxide in the body. I also take Pine Tree Bark Caps with L-Arginine to work synergistically in support of healthy blood vessels, improve glucose metabolism, boost insulin sensitivity, and reduce overall cholesterol levels.
