VetriScience Vetri Science Lysine Plus

I’ve been giving my cat this Lysine powder for a few weeks, and it’s been great! She actually enjoys the chicken and cheese flavor, which makes it really easy to give her the supplement daily. I’ve noticed her sneezing less and her eyes and nose seem clearer, which is such a relief. The powder mixes well with her food, and the capsules are convenient for travel or when needed. It feels high-quality and safe, and the 60-count supply lasts a good while, making it worth the price. Overall, it’s a simple, effective way to support my cat’s immunity and help with allergy symptoms, and I’d definitely recommend it to other cat owners.

I used this lysine powder for my cat when we were dealing with some eye watering and sneezing, and it helped keep things more under control. It was easy to mix into food and didn’t seem like a struggle to get them to eat it, which was a huge plus. I liked having something simple I could add daily that actually felt supportive for their overall health!

I have had my cats on these for years now, I’ve lost count of the amount of packages that I’ve purchased. This is the only brand that I will buy because it’s the only brand that my cats will eat. I have to cut them in thirds for my cats or they are too tough to chew and they won’t touch them. I cut the tail off and then the main part in half, perfect size for them. Once I do that they get excited for their treats. I got one of my cats when she was 10 weeks old and noticed that she was sick right away. The vet explained that she had a cold caused by the feline herpes virus. She’s twelve now and if she doesn’t get the chews then she’ll have a cold within days. A couple of years later, I adopted a two and a half year old male cat that also has feline herpes. Without these chews his eyes get junky and he gets the cold symptoms just as quickly. They both know when it’s treat time and will sit in front of the counter and meow until I look at the clock. I recommend these to anyone that has a cat with feline herpes. If your cats won’t eat them, try cutting them in half, it might help; did with mine.

I’m really happy with the VetriScience Lysine Powder for Cats. It’s easy to mix into my cat’s food, and she doesn’t seem to mind the chicken & cheese flavor at all—which is a big win. I like how simple it is to add into our daily routine, especially for supporting overall wellness. The powder blends well and doesn’t leave a mess, and the container is easy to use. After using it, I feel more confident that I’m supporting my cat’s everyday health in a simple, stress-free way. Overall, I’m very satisfied with this product and would definitely recommend it to other cat owners looking for an easy supplement to add to their routine.

He started sneezing periodically for 2 days, and I noticed one if his eyes was watery and a little red, he was tearing from that eye (clear tears). On the third day he started squinting and rubbing it. I read the reviews for these chews and figured I'd give it a try before taking him to the vet (which I am SO thankful I did). After ONE day he started sneezing less, on the second day he probably only sneezed once or twice and his eye was starting to look better. By the third day he was back to his playful ways, terrorising his sister (they love each other, really). I followed the directions on how many to give them a day, and will purchase again if the symptoms flare-up.

Yes! It will help! I have a Siamese, Maine Coon, Tabby, Mutt :) that has very bad nasal discharge and post nasal drip so bad that makes him throw it up with his food! Yuck! He was not getting any sleep over his continual coughing, sneezing, and throwing up. I gave up taking him the vet since they would just give him antibiotics that would slow it down for a bit and then it would come right back, so instead of allowing him to develop a resistance to the antibiotics I opted to wait until I could find a better answer. Within a few days of starting the Vetri-Lysine Plus his sneezing and stuffy nose subsided, and he stopped coughing almost entirely. I have to give it to him 2 times a day about 12 hours apart for best results. The added advantage is that the DMG worked to help reduce his sore kidney issue that I was dreading to take him to the vet for. Siamese are known to develop kidney issues, so I was pretty sure there wouldn't be much they could do for him since he is 14 years old. His kidneys don't bother him at all any more! I started giving all my cats DMG since they are all old. It is dosed out every other day with canned food from a bulk form of DMG I get from Amazon (he gets extra now) and I am amazed at all the problems it has cleared up. I haven't slept in almost two years, since I started taking the DMG daily I sleep really well, and I have been dreaming! After 20 years of no sleep to speak of, and trying everything there is to try--the DMG worked! The DMG is a really good reason to buy this version of L-lysine, other brands don't have it. My cat did not like it at first, but the other 4 did, so I had to force feed it to him. However, after he realized he could breathe better he no longer resists. He takes it twice a day without any argument now! The Rosemary is a product stabilizer used in place of BHA/BHT, which are 2 very bad chemicals. I'll take the Rosemary over the artificial stabilizers, so far have seen no ill effects in my cat from the Rosemary. I've been using the Vetri-Lysine Plus for almost 3 months now and my cat is doing very well!

I purchased these in 2025 and all three packages were dated to expire 1 month from date of purchase. You could clearly tell they were old , dry and hard. I purchased from chewy and they are fresh and soft. Chewy has much higher quality. Be aware they are not RETURNABLE.

Quantità minima

Cat started to feel better after using them He had a skin allergy (had bold spots) Vet suggested those pills

Got a kitten who has a little cough going on.After a week he is doing so much better.

Disappointing to order cat food from Amazon US. Last time all the cat food got stopped by customs. Some went thru yet the food inside the cans became all watery and poor quality. I thought these health supplements would work better. However, the tablets inside became very dry and hard. Difficult to get my cat to eat them. Yet I paid a high price for the item. Disappointed!

L-Lysine contenant en plus de la DMG Diméthylglycine (appelée vulgairement vitamine B15) 2ème achat depuis avril 2019 JE CONFIRME SON EFFICACITÉ: Produit qui a beaucoup d'appétence au parfum très agréable - forme d'un petit poisson d'un peine 2 cm de long, facilement sécable en 2 au besoin. Mon chat le mâche sans difficulté: il en raffole. Mon chat auparavant avait les yeux larmoyant rouge d'irritation des canaux lacrymaux et mettait des gouttes partout sur le plancher, avec une tendance à sa moucher même si ce n'est que des éclaboussures claires. EFFICACE dès le premier mois de traitement: j'ai commencé par 1 "gomme" matin et soir pour tester si le chat supporte le traitement, puis au bout de 2 semaines 2 "gommes" matin et 1 le soir (le chat pèse près de 6 kg). Il n'a plus les yeux larmoyants de larmes rouges/marron. Je fais maintenant des cures de Vetri Lysine Plus occasionnellement suivant les récidives de cet herpès oculaire.
