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 value

No fillers, or hard to swallow tablets. If you are looking for healing of the nervous system due to viral upset or injury, "two a day keeps the doctor away"!

wouldn't be without it

I suffer from cold sores that seem to only make an appearance when I am under stress. Taking lysine most definitely and absolutely helps to keep them 'at bay'. I only wish they offered a 625mg capsule as research indicates that taking 1,250mg daily is what your body ideally needs. Lysine is one of my vital daily supplements (x3).

Preventing outbreaks of HPV

I take these supplements together with Vit C w bioflavonoids (Thorne) to keep any outbreaks of the herpes virus away. That, and avoiding nuts, seeds, chocolate seems to be working for me. I take two-three a day. This is a good and affordable.

Its for my cats

This helps with eye infection and discharge in kittens, runny nose and sneezing in adult cats. DO NOT give this to your cat for more then two weeks in a row. It may cause a deficiency in another amino acid
