Love for my cat

Posted by Reviewer2335409 on May 06, 2008

Hello, I purchased this product to help out my sick cat. She has the herpesfeline virus. Before taking this product she was much worse off. Now she seems to be eating more, has more energy and her eye looks much, much better. I am not a fan of drugs and chemicals and so this natural remedy has helped her atleast reduce the time of sickness. I love her and would like to keep her safe and happy. Thanks for helping me do that! Sincerest Gratitude, L. Williams

Multiple benefits from L-lysine

Posted by Reviewer3323341 on Sep 25, 2011

In addition to placating the active herpers virua, L-lysine is one of the amino acids that can be used in complex with others like L-Methionene and L-Carnitine for clearing liver fats. Dr. Linus Pauling claimed that large doses of Vitamin C with certain amounts of L-lysine would actually pry lipo-plaque loose from sclerotic arteries.

It works

Posted by Reviewer3359969 on Aug 28, 2010

I've been using this L-Lysine since I got genital herpes. It helps a lot and is affordable. A lot more affordable than the prescription Valtrex. I hoping with the help of this product and watching my diet I will be able to get off of the Valtrex.

Best viral protection!

Posted by Reviewer1993634 on Feb 02, 2009

I can't eat chocolate or other high-arginine foods without having this handy! When mono is going around I make sure to take it daily.
