About This Product

  • Supports optimal arterial function
  • Non-GMO and gluten-free

L-arginine is an amino acid that the body converts into nitric oxide, a vasodilator that promotes circulation and healthy cardiovascular function. While l-arginine is produced naturally by the body and obtained through diet, some individuals may struggle to get enough of it.

Formulated with 700mg of l-arginine per serving, these caps from Life Extension are a convenient way to ensure you maintain healthy levels of this amino acid.

Superb Skin Supplement
I'm am more than thrilled with the results of all my supplements that I've chosen to purchase from Life Extension. I have girls more than half my age now asking me to email them my list of Life Extension products so they can age like me. SO happy with the results that adding L-Arginine have produced. When I combined it with Lysine and Proline, my skin looked years younger.
