    Ok I love these.. as a cold sore sufferer myself I found that taking these pills do help... but here’s another thing.. I made my own paste to put on top of my cold sore as well and it worked unbelievably. Here’s my concoction... grab one or two of the pills.. get a small medicine cup, open the pills and pour in the cup, put a few drops of tea tree oil, and a few drops of peroxide, and some sea salt... voila... works sooo good! I leave it on all night or for an hour or so when I have time. This is the only thing that has actually brought my cold sore down dramatically. Do try!! As well as taking these pills too.

    I have recurrent aphthous stomatitis triggered by tomatoes and this has made me never have a trigger again (when I do not forget). I take one of these every morning and have not had a trigger when I remember. I occasionally forget, eat something with tomatoes (its hard to avoid them), and will get a trigger. When I do have an outbreak I take 3 of these a day and it seems to decrease the time I have an outbreak. I hope these reaches someone with RAS well, it took me 19 years to find a solution.

    Ive ordered these easy-to-swallow capsules L-Lysine from Amazon for several years. I am thankful to be able to depend upon Amazon to provide this great value pack for me. Thank you.

    This is a great product for cats with feline herpes virus, an incurable and unpleasant respiratory illness that causes the cat to continually sneeze and suffer from sores in the mouth, discharge from both eyes and nose, and possibly tooth resorption as well. Although there is no cure for feline herpes and the infection is lifelong, l-lysine does a great job of eliminating the respiratory symptoms since it inhibits replication of the virus. This is well worth the expense of the supplement since feline herpes if untreated can lead to blindness. NOW foods l-lysine is the same strength as Viralys, which the vet prescribed for my ill cat. She did not test for the disease but told me to try Viralys and if it cleared up the symptoms (which it did) then the cat has herpes and needs to take l-lysine every day. She said that l-lysine is harmless to cats without herpes so there is no need to go to the expense of lab tests; just see whether or not the supplement helps reduce symptoms. I open a capsule and mix the powder into a small amount of baby food chicken and the cat eagerly licks it from the spoon. My cat is small and I have found that in the absence of stress, giving the medication once a day is adequate. Stress, illness, fleas, poor diet, extreme temperatures or anything else which can negatively affect the immune system may cause the feline herpes virus symptoms to re-emerge, so if I notice a runny nose then I step up the dose to twice a day. If you are on a really tight budget you can purchase one-pound containers of l-lysine such as Vitacost L-Lysine Powder 435 mg which has 822 servings for under $10. Viralys costs twice as much (about $22) on Amazon for 100 grams, and it is also loose powder so dosing again is approximate. The Viralys container does not specify how many servings are included so it is hard to compare price with the NOW product. However, I like the convenience of the pre-measured capsules and presume that they stay fresher than a tub of powder does, particularly in a humid climate, plus I am hoping that quality control is higher for supplements marketed for people, so I purchase the NOW product. Here are the dosing directions from Viralys, which is 500mg of l-lysine hydrochloride per rounded scoop mixed into a palatable base: Use in cats and kittens as a nutritional supplement for conditions responsive to lysine. The suggested amount for cats over 6 months of age is one rounded scoop (500 mg) given orally twice daily. The suggested amount for kittens under 6 months of age is one-half scoop (250 mg) given orally twice daily. The powder may be sprinkled over dry food or mixed with a small amount of canned food. I am considering taking this supplement myself, since some research suggests that lysine might help prevent bone loss associated with osteoporosis by increasing calcium absorption, although scientific studies are lacking. From UMMC: Most people get enough lysine in their diet, although athletes, vegans who dont eat enough beans, and burn patients may need to take a supplement. For vegans, legumes (beans, peas, and lentils) are the best sources of lysine, although it is also found in nuts, soy products, spirulina, fenugreek seed and brewers yeast. However, I presume that the marketing for this supplement targets athletes hoping to increase muscle mass rather than vegans or senior citizens, since I find it at the grocery store in the section with protein powders and supplements for athletes.

    Does what you may have heard from your doctor - helps humans recover from viral infections faster. Helps also to reduce recurrences of opportunistic infections (ie: cold sores.) L-lysine is ridiculously safe - its in every cell of your body already. Recommended for common cold, flu, mono, shingles, and - erring on the side of caution - anything else you suspect may be caused by a virus, even if you arent sure. Try 30 milligrams per day for every KG of body weight. Thats roughly one 500 milligram pill for each 35 pounds you weigh. I have a neighbor who was bedridden for almost two years due to complications related to shingles, and he credits L-lysine with his miraculous recovery - almost overnight!

    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..
