Product Overview

  • Sustained Plus Immediate Release
  • Promotes a Healthy Cardiovascular System

  • Vegan
  • Non-GMO and Gluten Free

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.

Adult Use: Take 2 tablets once or twice daily, away from food, or as directed by a nutritionally informed physician.

Circulation boost

Posted by Reviewer1316551 on Dec 24, 2009

This seems to be helping my fingers that lose circulation and pale when I get cold. I havent been using it for long and I have also added Natto and Niacinamide to my supplements, so I'm not sure if it is one of them all the combo that is helping.

for High bood pressure and more!

Posted by Reviewer1363742 on Nov 16, 2011

This helps my Husband keep his high blood pressure low and keeps him feeling much better at a great price. He also uses a few other supplements for this that we get through I-herb such as: pycnogenol, Lyc-o-mato, krill oil and grape seed extract. We are so thankful for these supplements we can purchase for a decent price here as he has been able to quit using prescription drugs that made him so tired and fatigued he could hardly even function. High blood pressure, strokes and heart disease run high in his Family and his blood pressure was so out of control that we are so thankful for natural supplements that keep him healthy. He does have to take 12 of these a day though, but there are extra benefits such as the drug Viagra should be helpful for that we didn't even expect! Thank you I-herb!

What a bonus!

Posted by BrendaRoss on Apr 22, 2013

I bought this product to control my blood pressure. The effect is immediate. My BP went from 160/100 to 125/82 the first day I started this product. However, there is one really important thing to remember: you have to take it without food, otherwise, it won't work. Besides, I used not to have good muscle mass, no matter how hard do I work out. But since I started this product, I have been building muscles with very little effort, I work out not even half as hard as before. What a bonus!

High Blood Pressure

Posted by 5720508950197905733 on Oct 02, 2014

I have had HBP for about five years with no help from Cardiologist so I started taking L-Arginine along with L-Citrulline and it helps control my BP Immensely. The best thing about these non drug tablets is that there are no side effects and I feel much better taking them. iHerb give me a quick delivery to Australia, they are efficient and the prices are very reasonable.I have been trying a lot of natural products to help my BP so read my report about Bergin whole raw Almonds. A natural product like this has also made a tremendous difference to my Bp and I can highly recommend them to anyone suffering with high BP
