I have used this product for a long time, and it is a great way to boost the immune system without taking another pill. I mix it in with the other liquid supplements/vitamins I take. Since I have been using this product the incidences of canker and cold sores as been greatly reduced.

This product is my life saver! The Quantum SuperLysine+ capsules are great for everyday prevention of cold sores, but when I'm sick or forget or on vacation (drinking, in the sun all day :P - my triggers!) this stuff will knock a cold sore right out! This product has saved me so many times, I'll never be without it. In fact every Quantum product I have tried has been great!
