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.

Great products -cold buster

Posted by Reviewer3119596 on Jul 09, 2017 | Verified Purchase

When I feel cold coming or when I feel first onset of cold sore, I take L-lysine and lo and behold it stays clear. I'm not joking it's been a saver. FIY tablets are on a bigger side, but it doesn't bother me. Check my profile for more info on what I have found to be helpful.
