This works so well!
I feed a colony of feral cats, and in the past week, about 7 of them had runny eyes, runny noses and sneezing frequently. They weren't feeling well and not eating as much food as usual. I tried this and within 5 days, they are all recovering. I put a little bit in each bowl once a day. They didn't notice anything unusual about the food, since there is no smell or flavor to it. NOW, they aren't sneezing, their eyes are clearing, and they are feeling much better! This really works and they are so grateful!

High quality and good value
I have a cat with feline herpes, and Lysine makes all the difference in her ability to breathe well. This bottle from Now Pet Health is a great value in comparison to the major competing brand I'd been using for years. It works just as well and lasts a little longer for a lower price. It's easy to measure with the tiny included scoop. Without lysine, my cat is congested. When she's congested, she doesn't eat. This is vital to her health. Both of my cats like the taste. I'm thankful to have found this product.

Works great
Seems to be helping my cat and he’s super picky and eats it just fine mixed in his we food!

A great deal, but does not work for my cat
My cat has feline herpes and is very sneezy and snotty when he goes through flares. He gets Claritin and a lysine supplement every day, and that helps a lot. I usually use Viralys (500mg lysine dose), but wanted to try this supplement since it is cheaper and the dose is lower. Unfortunately, the twice weekly dose did not work for my cat. It's not surprising given that the Viralys is 500mg of lysisne twice a day and the NOW supplement is only 250mg of lysine twice a week. I switched to giving the NOW lysine daily, but he is still sneezing snot everywhere. I may try giving him 2 scoops a day, but it feels like a lot. Anyway, I'm glad this product works for other cats, but we will have to go back to the other supplement once this one runs out.

Hope it works!
Just received this today. Also first time trying it out on my cats. They are all going through feline herpesvirus symptoms right now. I’ve tried L-Lysine treats and gel and they won’t touch it. I tried mixing the supplements with wet food and they are not easily fooled. This however does not have smell. Mixes well with wet food. I like the NOW brand so I’m confident that the quality is outstanding. Hoping that the health benefits of this supplement we will see improvements. Time will only tell.

Good stuff
I love the fact that my cats do not even notice this stuff is in their food and also that it is good for their health. Very reasonable price for a big bottle. I did not see diarrhea nor throwing up after eating it. I also do not notice any smell and I’m glad my babies are having this in their daily feeding routine, it will save me trips to the vet.

Definitely helps. Do not use in place of meds or proper vet care.
This helps. It's not a "cure" for anything, but it cuts back on allergies and illness in my multi cat household.

It's Vet recommended. 🤷🏻♀️
Pros: Clean ingredient list ✔️ Large size for the price ✔️ Health benefits are vet recommended ✔️ (this is one of the top recommended companies) Cons: Tastes & smell well tolerated across the pride ❌️ Measuring Scoop ❌️
