Now L-Lysine is a Pharmaceutical Grade essential amino acid.

L-Lysine is an essential amino acid that must be obtained through the diet or through supplementation. Lysine is necessary for the production of all proteins in the body, and is required for the maintenance of the structural proteins collagen and elastin, which form all connective tissue such as skin, tendon, and bone. L-Lysine is also a precursor to L-carnitine, which is needed for fat metabolism and energy production. In addition, L-Lysine may help to support a healthy immune system and proper cardiovascular function.

Suggested Use

Take 1/4 level teaspoon daily.

Give it a shot

I originally bought this for my cat, but I started taking it myself for no reason other than it says "may help immune system" or something like that on the bottle. I just add a little bit to some water and drink it once a day. Seems to work...I only caught a cold once last year.

Thanks for your feedback!

L-Lysine for Momma's Cats

Posted by iHerb Customer on Aug 30, 2017 | Verified Purchase

I like that Now brand powdered l-lysine has no other ingredients at all. I use about 1/8 tsp daily for my cats and 1/4 tsp for myself. For felines, it's to help build up their immune system. I highly recommend the Now brand of l-lysine.

Thanks for your feedback!

for my cat

bought it for my cats, mix it with their food when they have sneeze, and it's always works to stop them to sneeze (or make it less) and stronger their bodies. Use [ZLD 107] (no space) for your order to get 5 % off

Best Lysine

Posted by Tazy on Aug 24, 2017 | Verified Purchase

probably the most efficient and concentrated way of getting Lysine, which gives you the biggest bang for your buck too. Taste is not bad at all, as it doesn't really have much of a taste in itself anyway. Dissolves very easily in liquids. Great that is is so pure, and has no other ingredients!

Thanks for your feedback!

Lysine for heart health.

Excellent lysine product. Seems more effective than others that I have taken. I use it in conjunction with vitamin C in following the Linus Pauling heart protocol.
