"I have tried other brands but continually go back to Twin Labs.
Their pills are easy to swallow, smell fresh (that sounds strange I know but others I have opened smelled like nothing or cardboard), I have not had any ill effects such as stomach upset when taking them and they seem to help especially during the winter months as those around me come down with the flu and other ills."
"where i had slight problem once i took this i had big problems... as i stoped it returned back the way it was before.. thank god! i will never complain again and i will never ever take this product again!"
"Product is good. I like the capsule. Get that coldsore feeling or any herpes type situation? Take Lysine. It has helped me 100% of the time hands down especially if I catch it before it erupts into that painful thing - it never makes it to the sorry, painful state. Even if I'm a little late, the heal time is shortened considerably. This is what I do. I take a Lysine on empty stomach a couple times a day until the feeling passes, If you started late, just take it until the sore is healed. If it feels like it's coming back take it another day. I like the capsules because it's easier to swallow - Sylvia"
"I use this product to heal mouth sores and even after I sometimes bite the inside of my mouth. I believe it facilitates faster healing and am glad I found out about it. You may want to give it a try for yourself."
