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

Great for the price

Great supplement for the price!

My friend used this to get rid of a cold sore. I used it to help my cats recover from cat flu. The right dosage for my cats was 1/4 of a tablet crushed and mixed with food. Its tasteless so they dont reject it. Easy peasy. Worth every penny. And I am fascinated by a supplement that works for both people and pets. Hm... very interesting.

My husbands doctor can’t believe it but it works!

Use thie supplement very day. Inly complain is very difficult to swallow. Wish they would sell them in 250 mg and on capsule form.

Ive taken Lysine everyday for nearly 25 years. Not sure if there is any science behind this, but if I dont take them regularly I tend to get bad canker sores (they hurt!). But if Im consistent in taking lysine, then everything seems to be fine. These are a great supplement and easy to order from Amazon.

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.

L-lysine is my go to for any mouth issues whatsoever and this stuff helped me through a late-in-life removal of tonsils and follow up throat treatments. Putting this on subscription to make sure there is always some around.

I have been reading a very useful book - ‘Restoring Your Digestive Health’ - by Jordan S Rubin and Joseph Brasco, both MDs. They have a section titled ‘Sub-Par Supplements’ in the book, and interestingly, this section lists amino acid supplements. Many Amino acid supplements are sold to athletes and bodybuilders to help them build muscle strength. The problem with these supplements, however, is that they are a far cry from the amino acids in food. In the protein from food sources, different kinds of amino acids are bound together in long molecule chains, but in supplements the amino acids are free form or unbound. Each type of amino acid is sold as an isolate. Research suggests that these isolate, free-form amino acids are not absorbed adequately. Cofactors present in food sources probably help the body metabolize amino acids, but those cofactors are not present in free form amino acids. As long as you are getting enough protein in your food, you do not need to take amino acid supplements. Consume lacto-fermented foods and take high quality digestive enzymes to improve your protein digestion if you feel that you are deficient in amino acids. In general, we do not recommend these supplements for most patients.

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!
