NOW Supplements, L-Lysine (L-Lysine Hydrochloride) 500 mg, Amino Acid, 250 Tablets

A pharmacist recommended L-Lysine when I had a very bad case of bronchitis after moving to NYC to work on my doctorate degree in voice. I had been coughing so much which is definitely not good for a singer! An essential amino-acid, it is very good for stress. I heartily recommend it to all in stressful situations and to help general health.

Ive battled fever blisters forever, since I was a little kid. In doing some research I came across people saying that Lysine can help prevent them. At first sign of feeling one coming on, or even if I just know that Im feeling run down and I might have one pop up as a result, I take four of these. I havent had but maybe one fever blister since, and I was breaking out regularly for a while. Glad I found this.

Bought to treat shingles. Results in 2 days. Also works for mouth sores (canker sores). Recommend this and tea tree oil/and neem oil topically to clear shingles.

Ive been taking L-Lysine since 1968 and dont get sick. Getting scheduled vaccines and a good diet also help.

Probably placebo

I am incredibly prone to cold sores (especially during the start of a cycle - because yes Im that lucky.) I dont just get a tiny little cold sore thats a minor irritation. These suckers spread across my entire lip, they itch like mad crazy, blister like someone lit my face on fire and take a good 10+ days to heal. Then one of my friends mentioned that taking Lysine helps reduce the duration of time it takes for a cold sore to go away. So when Id get one, Id pound the lysine and sure enough, the cold sore would either go away or shrink down to a tiny little thing that was barely noticeable. Once I realized it was working, I decided to take Lysine regularly, and I no longer get cold sores. YAY!

I love this product - vegetarian and a great price. I take this daily to prevent cold sores. If you are looking for lysine for the same reason, please try it! I was getting cold sores weekly and that was unacceptable to me. Im a stressed out person and I get cold sores when stressed, so taking lysine daily and staying hydrated have changed my life! Highly recommended.

I take these because I have always had a problem with canker sores in my mouth, but since I started taking this they have stopped. Took them daily at first now just 3 or 4 times a week. Good stuff

Product is quality

I have had oral herpes since I was a little girl and I’m in my 70s now. I have been using this product for many many years and if I take it on a daily basis I do not have the breakouts that I used to get. If you feel a tingle on your lips or nose take several of these and the sore will not come out.
