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

I take two pills a day, and I havent had any canker sores since I started. If I forget to take them for a day or two, they start coming back. I gag easily on large pills, and these are very easy to swallow.

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.

Thought I was getting capsules, which I take and I also give to my cat for a health condition. I can take the tablets myself but prefer capsules. Didnt notice until I opened it. Ill have to order more for my cat.

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.

I’ve struggled with occasional canker sores for years and the dentist has had no solution. I found an article suggesting these and it’s worked like a charm! if I feel one start to come on, I take 1000-2000mg everyday and it goes away!

Great for the price

Pill to large

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.
