Vitacost L-Arginine Description

An essential amino acid that supports healthy circulation and may play a role in supporting good heart health.*

What is L-arginine?


L-arginine is an amino acid produced by all tissues of the body. It’s considered a conditionally essential amino acid, meaning the body can synthesize sufficient amounts on its own under normal conditions. In certain situations, the body’s demand for L-arginine increases, but the body may not produce enough, making supplementation beneficial.


How does L-arginine support health?

  • L-arginine is a precursor to nitric oxide, an important molecule that promotes vasodilation (relaxation of the blood vessels), which is important for healthy blood flow*
  • Supports healthy circulation*
  • High dose L-arginine may help to maintain blood pressure levels already within normal range*
  • L-arginine may be a valuable nutrient for men’s sexual health*

Why choose Vitacost L-Arginine HCl?

  • Supplies 500 mg of L-arginine per single-capsule serving
  • Contains 100 servings per bottle
  • Great value!

i have taken it daily since it arrived, and believe i can already feel the effects after a weeks worth of taking it. Of course i will be back to buy more ! you cant beat the price, or the product May 18, 2013
L-Arginine Supplement I bought this L-arginine during a BOGO sale. I usually purchase NOW brand - a 250 capsule bottle, because I get the best price for it but this was less expensive and I notice no difference than the NOW brand. I'm pleased. January 19, 2013
Good price and work good. I have tried different brands of Arginine, the Vitacost brand just seems to work better for me. The price per serving is much cheaper than other brands. January 15, 2013
Twice Daily Better Than Once I switched from 1000mg once daily because the doctor that recommended L-Arginine for me said our bodies can utilize only about half that amount at one time. Splitting the dose into two makes for less waste and a more prolonged availability of the amino acid. Makes sense to me! Of course, I have no idea whether or not this product "works," but I have been pleased with the cost and simplicity of the Vitacost brand. I trust that their products are tested and verified, and so will continue to use them unless I find out otherwise. November 23, 2012
I like the arginine orinthine combination,I am feeling and getting stronger in the weight room August 11, 2012
