Product Overview

  • Dietary Supplement
  • Free Form

L-Lysine is an essential free-form amino acid which acts as a precursor for other amino acids, including L-carnitine (needed for fat metabolism). L-Lysine is crucial for the formation of collagen, a major part of the body's connective tissues. L-Lysine also contributes to energy production when converted to acetyl coenzyme A, one of the principal fuels for the Krebs Cycle.

Suggested Use

1 tablet daily.

Good Price

Posted by Reviewer2865758 on Jun 11, 2008

I take 2000mg L-Lysine to keep cold sores and boils at bay. I am amazed at how many doctors are not aware of the skin healing properties of L-Lysine.

L-Lysine, Not just for herpes -

Posted by Reviewer1709615 on Nov 10, 2010

I use L-Lysine regularly to prevent my face from breaking out. Not all L-Lysine is created equal & some other brands I've tried do not seem to help at all but I love the Source Naturals products. One 1000mg tablet per day keeps my face from breaking out. I can definately tell a difference when I stop taking it & if something pops up this helps clear it up almost immediately.
