Product Overview

Now Bottle


  • Supports Healthy Connective Tissue*
  • Supports Calcium Absorption*

L-Lysine is an essential amino acid, which means that it cannot be manufactured by the body and must be obtained through the diet or by supplementation. Lysine is necessary for the production of all protein in the body including hormones, enzymes, and antibodies, as well as carnitine and collagen, which is the structural protein forming all connective tissue such as skin, tendon, and bone. L-Lysine also plays a major role in calcium absorption. Some evidence suggests that L-Lysine supplementation may help to support a healthy immune system as well as proper cardiovascular function.*

Only drawback is the tablet size....I do not crush them by a tablet crusher as I feel they might be enteric coated to avoid them to be harmed by stomach acid as they have a thin paper type layer on them which can be seen when you break the tablet.

Great deal for the price, but it is not humanly possible to swallow these tablets. I give it a 5/10 because the pills are actually impossible to swallow - as soon as they get wet they get pasty like concrete. I'd recommend not even trying to swallow them whole, but rather crush it up or chew it because that's the only way to get it down. Other than that, the stuff inside the tablet is high quality. Stacking with NOW L-Arginine & Ornithine and the combination is really powerful!


The caps are huge and had to put down. but it is a great deal for the price.
