For Herpes Simplex, Suppression "I have IBS with alternating diarrhea and constipation. I tried L-Lysine a few months ago but thought it increased diarrhea and abdominal cramps. Continuing to break out, I tried the Lysine again, routinely twice daily. Unfortunately, the diarrhea and abdominal cramps have returned, and I'm stopping the Lysine immediately."

For Herpes Simplex, Suppression "I tried this after I kept getting cold sores, and it has really helped. I never had these before until I started wearing a mask all the time. Anyway, this really works: 1000 mg, 2 times a day I started with, and now decreased to once a day since I have no cold sore. GREAT stuff!"

For Herpes Simplex, Suppression "One day after starting the L-lysine, I have horribly swollen lymph nodes in my underarms. It's been 3 days, and they are still painful and swollen. I did have smoothies each a.m. with mango and yogurt, which I read are high in lysine as well. I am stopping use due to this reaction."

For Herpes Simplex, Suppression "I tested L-lysine for over a year to see what results I would get for HSV 1 and 2. When 50 mg was taken daily, it completely suppressed HSV 1 and 2, and I never had any outbreaks. However, after stopping daily dosing, the outbreaks returned and became worse than before, in both frequency and severity after stopping L-lysine! The more severe outbreaks stopped after my body could fight off and suppress the virus as it did before using L-lysine! The good news is that after a number of months, your body will return to pre-L-lysine supplementation levels, and the number of outbreaks will return to what they used to be. I normally only get an outbreak a couple of times a year when the seasons change from fall to winter and from winter to spring, but when I used L-lysine daily, I never got an outbreak for the whole year plus that I used it. For people that have less severe cases of HSV 1 and/or 2, you may consider supplementing with L-lysine only as needed to stop a breakout instead of taking it daily."

For Herpes Simplex, Suppression "I have been using 1500mg (500mg/3x a day) of L-Lysine for years with no ill effects. No Herpes Simplex breakouts either. I keep meticulous records of all my blood work and it has been nearly perfect."
For Herpes Simplex, Suppression "I never do reviews, but I'm hoping this will help someone. I was diagnosed with herpes simplex virus type 1, orally and genitally, that I got from a loser who knew he had it but did not tell me. I recently had a genital outbreak and started taking L-Lysine as soon as I felt it coming. The blister did show up but started fading away and was almost gone after 4 days. I took about 3,000 mg of L-Lysine a day. I'm not sure of the recommended dose, but I did not have any side effects. This stuff really does work for genital and oral herpes!"
