    Greater than one week

    This maybe a miracle! Ive had cold sores for years and I hate them. I tried otc and prescribed ointments, but they still last for a week and look gross. Im totally sel-conscious. Now that I have kids, Ive become overwhelmed trying to make sure I dont infect them. This led me to explore any alternative I could find on the internet. I tried many things, but L-lysine is the first product that should immediate and remarkable improvements. Now as soon as I feel the tingle, I double the dose. Sores barely become noticeable and last for a day it two!!! Its amazing. I cannot recommend this product enough!

    I have been taking one a day for about a month. Last week a had a pretty severe cold and knew i was going to end up with at least one cold sore. Sure enough, two started to develop so I upped my lysine to 3 or 4 day day. The cold sores went away within TWO DAYS! Those of you that suffer from cold sores know that they would normally last a week or two. I am so happy! I know that lysine works to help your body fight viruses like cold sores, and it really showed. Both of my cold sores began to die and shrink before they even got to the scabbing phase.

    I was sick of paying 17 bucks for the smallest tube Ive ever seen of Abreva to treat my cold sores. I needed another solution and I just searched and searched. Then this amino acid popped up and I gave it a shot. Im very glad I did. I take it ever single day. Ill take 1000 mg everyday and when days that I feel a cold sore coming or a big event Im nervous about is happening Ill take 2-3000 mg for 3 days straight. It works amazing. I would get cold sores one after the other after the other. Maybe one a month. Thats awful and it looks bad. I get maybe 3 a year now more like two and they last very very short amount of time. Now if I actually see a cold sore coming in I will using L lysine plus which is a very inexpensive cold sore medicine along with this. other than that the cold sores are so reduced since taking this that I cant recommend it enough. OH and dont buy the 1000 mg pill is like a horse pill and terrible to try to get down. Get these take two and thank me later.

    My son used to get fever blisters (a lot) that I’d treat with expensive creams and ointments. I researched so much until I found this! He’s 10 years old thus can’t swallow a pill yet so I open the capsule and put it in his morning smoothies, oatmeal, even yougurt. Now then, he still gets a tiny fever blister (not as often) even when taking L-lysine but it only last hours and it’s GONE!

    We have an almost-two year old pup that recently contracted warts (thanks, dog park!). in her mouth and around her gum line. They were AWFUL looking and we were told by our vet that we would need to let her ride it out (as long as she was still eating/drinking regularly) so that she could build up antibodies to fight them off - otherwise there was the potential they could come back again. We did some research and found that Lysine could be a great way to help build up antibodies, and cut down on the recovery time (which ranges anywhere from one month to six months). When we received these, we opened the capsule and sprinkled one pill (500 MG) in her breakfast, and one pill during her nightly meal (we were using a wet food, so this was easier to make sure she didnt spit it out). Within five weeks, she was completely wart-clear, so we were so grateful to have come across this resource.

    I like taking this product. I purchased this mainly for my skin. I read online the benefits of taking lysine for battling against fine lines and wrinkles as well as clearing acne and for cold sores. I thought wow this would be awesome to take since I have developed cystic acne recently. I started taking this almost two weeks ago for 3 times a day and I can see a change in my skin as I do not get as much cystic acne as before and my skin is a little more clear. Im not able to rule out this product as the cause of having less acne issues because I was also taking IntestinePro, Bioschwartz colon cleanser and the Mario Badescu buffering lotion. Maybe all the combinations of medicine and detoxing helped. Im not sure but I will continue taking this product since Lysine has many other benefits. The price is so convenient as it is only $10 and the bottle is huge consisting of 250 capsules. Worth the money.

    When I search for NOW L Lysine 1000 mg it quickly comes up with a bottle that says 1000 mg. But when you click on it, it goes to the writing and it is changed into L Lysine 500 mg. I had this on auto ship but now have cancelled that order. I tried 2 times to talk to technical assistance and thought I had this corrected. But I got caught again. I do like the 1000 as that is the dosage the doctor had recommended for us. So for the price, it is more expensive because you are getting just half of what you think you are getting. If you want 1000 mg, you must take 2 tablets instead of just one.

    I purchase many NOW products. Tried this lysine product on cats who take this supplement daily, vital for their compromised immune systems. Unfortunately, it did NOT work well, as with most other lysine brands. The cats started showing symptoms of their chronic infections a few days later. After putting them back on the other (more expensive brand) they went back to remission.... Every family member takes 2,000 mg of lysine daily, so we rather pay a little more money on a brand that works well on cats as our control group. To be fair to NOW, the fact that their lysine does not work well in cats, does not necessarily mean that it will not work well in humans -but for me, it is a semi-scientific observational indication to stay on a brand that works well in our control group

    Now Lysine is really good and its price point is very competitive with other brands of lysine that are on the market. I have always had a good experience with Now Lysine products and I would recommend them and I would recommend their lysine product.

    Went through a 10 year span where I was getting one cold sore after another. I purchased a bottle of this product to see if it would give me any relief. I took one-a-day til the bottle was empty and never got another cold sore. Once the bottle ran out and I failed to replenish my supply, the cold sores returned. I wont make that mistake again..
