NOW L-lysine 500 mg, 250 Capsules

This works very well for us, keeps cold sores from developing or helps so much if they do. I am prone to shingles so taking this product everyday helps keep that under control. I gave 4 stars only because I ordered a bottle on Oct. 28 and have not received it, was not in the box with other items. Havent been successful in getting another sent so Im re-ordering as we dont want to be without it.

Been using this for years... NOW is a great, reliable company. I take it occasionally when my body needs it, but mostly use it for rescue cats that need the immunity boost due to various ailments/conditions, including respiratory issues, viruses evidenced by other symptoms, lip blisters, etc. The gelatin capsule is easily separated to release the powder into wet food, liquids, etc. Great price, as well.

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.

This is a food suplement that I have used this product for many years.

I gave this to my dog per vets advice. He was on medication which brought down his immune system and caused some other issues. We have since gotten him off the other medication and have been giving him 1000mg/day for 3 weeks and his issues have cleared up. I have also been able to start giving this to our puppy who is having issues as his immune system has not fully developed yet. My puppys issues have cleared up as well within 2 weeks of starting this.

In the late 1970s, I worked in a hospital laboratory. My job was computers in a white room, particulate matter, temperature and humidity controlled. After one year of eating my hospital lunch and dinner on, what I didnt know at the time, the 6AM specimen cart for a 550 bed hospital; I got a recurring cyst between my eye brows. The Pathologist directed me to the best of the best dermatologist and he shoot it every month with some liquid. It worked for about 3 weeks, and again it would appear. I researched the issue (in the medical library), and found Lysine was the answer. Months later, I told the dermatologist of how it healed it within a day or so (500 mg caps). Saw my co-worker that used the same table 20 years later, he had the exact same cyst; what I call the Lysine Flush worked within 24 hours. After 20 years, it went away. The dermatologist stated (early 1980s), nothing in the medical journals indicated that herbies viruses were detectable in either of two areas, one of which being lips. To make the long story short, the one day Lysine Flush works better than prescribed medicines, it works like a charm. Last year, the ophthalmologist noted a sudden loss of vision in one eye--I did the Lysine Flush again and on the return visit, he said he had never seen the issue disappear in his career. It was the Lysine Flush (Now Brand). I normally do not take Lysine, but believe it may work as a prophylactic against more recent viruses. The flush I use, but not being a physician, take 2000 mg per day during these special times. Works on the flu, so I figure, only as a prophylactic it might help on a daily basis to slightly reduce health risks--especially when I venture out into the outside world. Take care and be safe.

Another excellent product from Now. I use their Niacin, Arginine/ Ornithine amino combo, and many other supplements. I am very pleased with this supplement. It is hard to find the branch chains together in high mg. I prefer to buy the separately for that reason. This product contains 500 mg of L-Lysine. Lysine is an amino acid that our bodies cant produce but that is essential for human health.L-lysine is important for proper growth and it supports other amino acids in converting fatty acids into energy and helping to decrease bad cholesterol. Some scientific studies indicate that lysine aids in calcium absorption and it is important to maintain healthy connective tissue. Lysine is especially good for athletes and is thought to help improve endurance and recovery. Many report that it has helped them with problems associated with osteoporosis. It is also recommended by many for the prevention and control of cold sores. I use this to try and increase my natural levels of HGH. I feel younger and have more energy while taking this product. I always receive high quality products form NOW, and I really trust this brand the most.

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.

good value

Great for immune support. Reasonably priced.
