Worth a try for immune support!
My overall opinion of this product is that it’s good quality. We have a 7 month old kitten that has suffered from chronic upper respiratory issues since we adopted him and through 3 rounds of antibiotics, he still wasn’t well. We decided to give his body a break from antibiotics and work on boosting his own immune system. I’ve been giving him immune supplements daily for months now and he’s in really good spirits. He has good days and bad days but it seems like more good than bad at this point. We used 2 different lysine supplements previously but I decided to give this one a try when the last one ran out and I believe it’s helping. He seems to be feeling better and less stuffy after having a dose of this powder in his food. He also doesn’t mind the smell or taste of it and eats it right up mixed in with his wet food. I’m really hoping after finishing a container of this, his immune system will be much stronger. Thus far, I’m happy with it. I like the additional benefits in it besides the lysine. It’s a unique combination that I haven’t seen with other lysine products. I’d definitely recommend giving this a try if your cat needs an immune boost!

Little Chleo
My cat’s eye doctor recommended L-Lysine for her. I have been using this brand for numerous months now. It is easy to administer as I put it on her wet food. So far she has been eating it with no issues.

My cats love it!
I like the ingredients in this L-Lysine supplement for cats. I mixed it into my cat’s wet food and they ate it with no issues. Smells a bit like the fish oil that is in it. I would buy this product again.
