What are Immune Support L-Lysine Chews?

Immune Support L-Lysine Chews are tasty, veterinarian-formulated soft chews that provide high levels of the amino acid L-Lysine for the support of normal respiratory and immune system function in cats. They also help maintain normal feline eye function and health. Each Immune Support L-Lysine Chew provides 500 mg of L-Lysine, in a delicious smokey fish flavored treat that cats love. The new and improved formula helps promote optimal immune system function, and the soft but chewy consistency makes them easy to give your cat as a flavorful daily treat.

Customer Reviews
Immune Support L-Lysine Chews is rated 2.0 out of 5 by 2.
Rated 2 out of 5 by from Need more options I agree with the other review, we need more options for l-lysine treats for cats. The one I buy at my vet is Enisyl-F Lysine Treats. My cats love them! But the price is expensive. Was hoping to get a price break here, but will go with what I know my cat will actually eat. Please offer it, it also has good ingredients and the option to give a smaller dose of lysine to my cat as needed.

Rated 2 out of 5 by from We have four cats and none of them liked these (and one of them will eat anything). I don't understand why Optix-care or other varieties of L-Lysine treats or capsules (to mix into food) are not offered on this website. The feline herpes virus is so common these days.
