    * This lysine is cheaper than other stores and it is the exact same thing. I take this so I don't get cold sores. It works

    * This Lysine works great for the occasional cold sore. I just start taking 2 a day it when I feel one coming on and it shortens the life of it drastically.

    * I have been using L-Lysine for some time to prevent fever blisters (cold sores) and it has always been effective. The last one pound bottle I bought did not seem to have the usual amount of the amino acid in the powder. I increased the amount I took after the first outbreak of fever blisters. Even after doing that I suffered with two more outbreaks of cold sores.

    The disappointing thing about this incident is that I contacted NOW by email and they did not even reply. I will be purchasing some other brand of L-Lysine in the future.

    * I have been using this product for several years to prevent fever blisters (herpes) and I never have a breakout as long as I continue to take the lysine. In addition to that, I've cured my dog's canine lupus by giving him a small dose of lysine daily.
