Immune Support Daily L-Lysine Supplement, Fish-Flavored Lysine Powder for Cats and Kittens, 3.5oz

GREAT!! Having tried other brands, this is my number #1 choice when I have sick, feral cats in my colonies. I feed close to 27, TNR'd cats in multiple locations & when they show up w weepy eyes, sneezing &/or signs of upper respiratory distress, I mix this in w wet food, adding a little warm water. The results have been amazing! Usually, I see results after the 2nd feeding. I just had a very sick male, I think he may have FIV but a URI was hitting him hard, he had stopped eating because he couldn't smell through the nose congestion.. I used sardines mixed w canned, tuna cat food & a little warm water w this Lysine mixed in.. he was in bad shape but the smell was enough to trigger him to eat & by day 3, he was remarkably improved, he's almost back to himself again. -- For feral colonies, this is perfect to help their immune systems! Not much is used each time so it lasts a while, a good value for the price. -- I use it regularly now for all the outdoor cats, I do recommend adding it to wet food w a little water so it dissolves. Trust me, this stuff is great for URI & weepy eye issues!

I purchased this as a replacement for another brand (Viralys) that I had been getting through my vet. One of our kitties had a "cold" when we adopted her. That "cold" just wouldn't clear up. She had a weepy eye and sneezles for weeks. When we took her to the vet, the vet said it was kitty herpes and prescribed the Viralys (at $30 a container). It's l-lysine in powder form; you sprinkle it on the cat food. There is no cure for feline herpes, but l-lysine helps clear up the symptoms. (For those who want to know how l-lysine helps, The Cat Doctor & Friends in Santa Clarita says, "We use L-Lysine to fool your cat's herpes virus into self-destructing by using L-Lysine, instead of another amino acid Arginine, when making new copies of itself. This decreases the amount of herpes virus in your cat's body and hopefully eliminates clinical signs such as sneezing or squinting one eye and reddish brown discharge. Green or yellow discharge from your cat's eye or nose is probably not feline herpes and deserves a veterinary visit.") The Viralys l-lysine powder not only worked great, clearing up the weepy eye and drippy nose within a remarkably short amount of time, it was also loved by all our kitties. (The vet said it wouldn't hurt any of them to eat it.) However, at $30 a container, and with the stupid mistake I made that wasted half a container (see below), I wanted to find a less expensive alternative. And I did. This product, the Tomlyn Scientifics l-lysine, seems to be identical to the Viralys, and costs half what my vet was charging me. My one concern was whether it would taste as good to the kitties, and it does indeed seem to. == My Stupid Mistake and How You Can Avoid It == When I first got the Viralys from my vet, I made a stupid mistake. I used the little scoop that comes with the powder to sprinkle the lysine powder on the cat food, and then I used the scoop to stir the powder into the food. Then I returned the scoop to the container. Those of you who are familiar with good sanitation practices will be able to predict what happened next: after a while, the tiny crumbs of cat food I had inadvertently transferred to the container gave birth to new life. In a few weeks, I saw suspicious little clumps and balls in the powder. I threw out the rest of the powder rather than risk making my kitties sick. After thinking about what I could do to prevent wasting my kitties' medicine (and my money), I realized the solution: put the powder into a shaker container so it never gets contaminated. After shopping around, I purchased the Kaiser Bakeware La Forme Select Sugar/Spice Shaker Set (available here on Amazon), which is just the right size for the powder. I'm using the shaker lid with the largest holes. Now all is well.

We have a three cat household, and it's important to us that all three cats stay healthy. Lysine is a good supplement to support immune function in felines, and all three of our roommates get a good slosh of this stuff with every meal. NOne of them have ever balked at the taste or texture, and they gobble up all their food. They've stayed healthy and feisty and very much themselves, and what could be better? Check with your vet, but lysine has been very good for our household.

My 7 yr old female cat suffers from gingivitis/stomatitis syndrome. Had all but lower fangs removed 3 years ago. Helped a lot but still has flare-ups 2-3 times per year (treated with prednisolone). Steroid very effective, but gradually frequency of flare-ups is increasing (worry about diabetes). So, am trying any and all strategies to prevent or reduce frequncy of flare-ups. Read somewhere a few cat owners claim lysine helped. (Counter intuitive to boost immune system since most Vets think malady is autoimmune disorder). L-lysine is easy to administer and cat seems to like it, and (maybe) has more vim and vigore - hard to know such things about cats. Dose is fairly small so container should last about 2 months. Using now for 3 weeks, but wont know if effective unless cat goes about 3 months without flare-up. Therefore, 3 stars now for perking up my cat, easy admin, cat likes, and affordable. If no flare-ups for next 3 months - then 5 stars for sure. ( I WILL update this review at that time) Update (March 12th) -------------------- Cat did have another flare-up back in December about 3 weeks after I started her on L-lysine, but by then she really liked the stuff and I already had it, so continued the recommeded daily dose. Also restarted her with prednisone (steroid), but at a significantly lower dose (about 1/5th the usual) and only every other day. Now, it's been just over two months without another flare-up. So, maybe this low dossage would always have worked, or maybe the L-lysine is helping after all. I don't know, and after 5 years with this oral inflamation problem, I don't care. Going back to my Vet this week for more of the steroid and will ask about odds that current low dossage will avoid diabetes. But, either way will now continue with the steroid/lysine combo.

My cat started showing signs of getting sick about two weeks after we moved to a new state, and at first I figured it was just allergies. But then he got tremendously worse; runny eyes that would seal shut, horrible runny nose, hoarse cough, and constant sneezing. It was awful! I took him to the vet, who diagnosed him with an upper respiratory infection. I was given expensive cat sized neosporin and antibiotics to help alleviate his infection. Nothing was working or making a change. Our other cat used to get a runny eye from time to time and the vet we used to take him to gave us Lysine treats, which cleared him right up no problem. I decided to try to get our sick cat to eat some of the treats, but since he wouldn't eat them, I had to pretty much stick them down his throat like meds. The next day he started making a turn around. It was a constant battle to get him to eat the Lysine treats, but we could tell it was making a dent in his overall condition. We couldn't afford to go back to the vet (which upon review actually way overcharges compared to other vets in the area) so I tried to look up a liquid or comparable form of Lysine to try to make it easier to administer to my sick baby. I found this supplement, and upon reading several reviews, was confident I had found something that would make a difference in my cats health. I AM SO GLAD I found this, because within a couple days of giving him a serving day and night mixed into a little bit of wet food, he made a GIGANTIC turn-around! He stopped wheezing, sneezing, and his eyes cleared up. My poor baby was back! I cannot thank this company enough for making a great product, one that I believe saved my baby's life. One little tub of this lasted about three months with daily regular servings, including the first three weeks of double for one cat. We just ordered our second tub a couple days ago and will continue ordering for the life of my babies. (also, one of the reviewers mentioned the symptoms my cat was showing alike to feline Herpes virus, I googled it, and that's exactly what my cat was experiencing. I encourage you to check with your own sources as well as a trusted veterinarian)

Works well. A couple eat it plain & I can mix it into wet food & they eat it. All my rescues had feline herpes ( one from the litter had to have an eye removed! He's heathy & in a good home now though!) so badly they couldn't open their eyes & we had to wash their faces with warm water every few hours. After several vet visits & a lot of bills & expensive eye ointments, pills etc. nothing was working. I found online an article on giving the cats 500mg of lysine 1-2x a day . Well I would have tried anything! That was 4 years ago- All the cats are FREE from any issues. I only give this once in awhile for maintenance & if I even think I see a leaky eye! But the lysine after about 4-6 months of daily use, cleared up all the cats ( 5 then) from any signs of issues! No more expensive & useless eye goop & pills that to pill a cat you better be in a hazmat with a space grade covering over that! Ugh I now tell everyone to put their cats with any signs of feline herpes ( crusty, leaky eyes & noses) to use lysine ! At first I gave 500 mg 2x a day to each. After it clears up a tiny scoop in their wet food keeps it at bay. After several months of constant use, they can be cured or at least my cats have not had any signs of flare ups in almost 4 years. I give this now in wet food that they all eat, 1-2 tiny ( included) scoops for a few days every couple months. The vets did nothing, the mess they gave did nothing but cost me a lot of money & my animals still suffered. This suppresses the virus in humans ( lysine pills, lip ointment ) so I suppose it works similar in animals. But it cured 5 cats for years+ . I'm so happy I found out about this. This brand works just as well as the more expensive brand I use to buy in the very beginning . I've even crushed up human lysine pills & given them that. This is easier ( cost a bit more but once it's under control , you will have this container for a long while!) Good luck & health to all your fur babies! Jenn~

I am a first time owner of a cat. Knew nothing about them except to only pet them when they ask for it and do it carefully or else! (Thankfully my cat, Panini, is actually very affectionate and adores hugs and cuddles). There was a day when I noticed Panini was sneezing, a lot. I had heard him once or twice sneeze but that's obviously normal. However, I knew something was up when it was consistent and we could hear him from the second floor. I didn't find it alarming at first since he had no other symptoms. He ate and drank water. Went outside and came back in to play. Had his night "zoomies" and playfully attacked our dog before rolling onto his back. He looked healthy and seemed fine. But after the second/third day of his sneezing, I finally looked online to see what it could be. I scratched off allergies since it was described as the "occasional sneeze"? I eliminated the flu/cold since he had no loss of appetite, his nose was not runny nor were his eyes producing any form of leakage. I did catch the recommendation of adding Lysine to their daily diet to boost their immune system and help protect their respiratory from infections. So I came here and found this product. Read how many reviewers gave it to their cats who kept sneezing and it helped. That was enough for me although I also felt better that it would help his respiratory system and overall protect him, something I wanted since he loves to go outside and there are countless strays he comes across so who knows what they carry. I did have to also purchase some wet food since I saw it was recommended to make it easier for the cat to digest. When I received this product, I was somewhat disappointed by the very small size, even more so when you open it and find the container only 75% full (like opening a bag of chips). 1 star for that. I followed the instructions and added 1 spoonful (it comes with a properly sized spoon) of the powder into his food, twice daily. I will have to say that it was within a week that I noticed improvement. The first few days, he was still sneezing but not as often as before. Once a week passed, no more sneezing. None. Even my mom praised this product and thought of getting some for us (until I read how for us humans, Lysine can give us kidney failure) Since Panini got better, I reduced his dosage to only one time a day and it still seems to work. Despite not being happy about the price and the small size, I will keep purchasing this product. Panini worth it.

In 2021 I brought home a new kitten. After only a few months he got very sick. I found out he had the herpes virus. I didn't even know they had sent his blood work out so, my other two cats were exposed. Every morning, I mix one scoop of L-lysine in each of my cats wet food. They never complain, always eat up, and so far my herpes cat has stayed healthy. I won't use any other product. One tiny scoop is enough for each of my adult cats.

We're really happy with this. My cat has had on and off problems with his eyes for years. Despite all efforts he kept getting problems. Since giving him this product with his food ( took him a couple of feeds to get used to it ) he's not had a problem for a long time now and seems happy and healthy

This really worked on one of my cat who had continuous sneezing, and my cats did not have an issue with the taste

My cats seems to like the taste or doesn't notice it in her food. I'm happy with the quality of the product.

Tomlyn L-Lysine Powder Supplement was as others have described it (not sealed and smells of yeast) BUT my cats seem to like it and the yeast etc are probably a;so good for them and my boys chronic eye condition seems to have improved.....

Seems to work well for weepy eyes (but doesn't get rid of it entirely), I mix it with wet food and my boy doesn't seem to notice the taste. Easy to use with the scoop.
