Product Overview


  • Amino Acid Supplement
  • Free-Form Powder

L-Lysine is an essential amino acid which acts as a precursor for several other amino acids, including L-citrulline (needed in the body for normal protein metabolism) and 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

1/4 to 1/2 teaspoon daily between meals.

iHerb Customer Reviews

Easy to use and keeps kitties healthy!

Posted by iHerb Customer on May 23 2016 | Verified Purchase

We use this all year round to keep our kitties healthy. Just a little sprinkle on their wet food and they are good to go. No measuring, no opening capsules. Nips a cold or virus in the bud so everyone is not sick all the time. We love this lysine!

Thanks for your feedback!

Cold sore relief

Posted by iHerb Customer on May 9 2016 | Verified Purchase

I've had cold sores for my entire life and lysine has never failed to give me relief. This one is excellent value for money vs tablets and great quality. I like powders as they tend to not have fillers and sugars in them.

Thanks for your feedback!
