> 3 dayI 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

> 3 dayI struggled with hormonal acne and saw that this product was recommended for an off label use to treat it. I was in the middle of a nasty breakout along my chin when I started this product. Within 2 days all my active pimples started to dry up and go away. After about 10 days of use I didn’t have any break outs. I take one 500mg capsule three times a day (with every meal). This product has done an amazing job at keeping my hormonal acne away.

> 3 dayThis 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.

> 3 dayI take this everyday because I get cold sores. When my son was first born I decided to start donating my breast milk. But if you take the rx to get rid of your cold sores you can’t donate that milk for up to a week after you stop the rx. With the lysine I can donate while taking it, so super safe (according to my dr and the human milk bank) to take while pregnant nursing. I also double up the dosage when I’m getting a cold sore and the healing time is cut down so much!

> 3 dayI ordered these after reading a peer reviewed article discussing the benefits of taking L-Lysine along with iron or vitamin D. I had bariatric surgery over twenty years ago and I struggle to maintain my iron and D levels. I started taking these as soon as the shipment arrived and last month, my labs showed a remarkable improvement! I am going to continue my regimen and see what my next lab report shows. I am just amazed that after spending so much money on a variety of supplements, to discover that all I needed was to add L-Lysine to my regimen!

Greater than one weekI ordered this mainly to take along with my other supplements for lipedema and lower leg circulation but didnt start taking it till I felt some soreness and skin sloughing in my mouth. I thought it might be the start of an apthous ulcer, I remembered I had lysine and took them 2x/day already by the third day it was healed and nothing came of it! As a hygienist I recommend this as a natural alternative for oral lesions but never had to use it now I can say it worked for me as well. hopefully it will help repair the collagen and connective tissue in my lower legs too.

> 3 dayL-lysine is a great supplement that a lot of people dont even know they should be taking. Ive taken Lysine supplements off and on for several years, recently I kept getting weird sores in my mouth so I bought these Now Foods Lysine supplements and within about a week or so they were gone and havent returned after several months. Lysine is good for several things in your body, its an essential amino acid, its great for your skin among other things. Now Foods have always been a great dependable brand with low prices, I know I can trust almost any of their supplements.
