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

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.

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.

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.

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.

I received my order quickly. I couldn't find the other immune supplement that i ordered last time so I decided to go with this one. My cat has FIV. To my surprised this immune supplement worked on the very first day. The last supplement i had used took a week to start to work for my poor boy. So I am very pleased with my choice to go with this. My boy loves the flavor, gives him a nice soft shiny coat as well. Helps with his eyes, nose, his breathing and anything else that helps him with. It is a white power and has a spoon that comes with it. The size of the jar is pretty decent size. He gets it every morning in his food. I definitely recommend this!

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

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.

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.....

My two cats love this. It must be tasting so good cause both my cats eat so well when I mix this powder with wet food. Not sure if it’s because of this powder, but they look more active and their coat has been shiny after giving this powder.
