Product Description

tomlyn header
L-Lysine Header

Tomlyn L-Lysine Immune Support Gel is a great-tasting maple-flavored gel for cats and kittens of all ages. We developed our veterinarian-quality product to provide immune support for cats and kittens to help maintain a strong immune system, normal respiratory function and eye health.

Our Lysine products are used and recommended by veterinarians for feline health conditions that are responsive to L-Lysine.

L-Lysine Immune Support Gel helps manage the following issues, which can all be signs that your cat has a weakened immune system:

  • Sneezing, Runny nose, Squinting, Watery eyes, Inflamed eyes, Eye discharge, Nasal discharge, Congestion

Tomlyn L-Lysine Powder

Veterinarians recommend giving cats 1000mg of Lysine daily. Just ½ teaspoon of our Lysine gel twice daily (¼ teaspoon for kittens) provides the recommended daily dose of Lysine.

If your cat is fussy or will happily eat anything, our daily L-Lysine supplement for cats in gel form is perfect for cats who enjoy self-grooming and is the ideal choice for cats who are known to be picky.

My cat has always had goopy eyes. Vet says it's a herpes virus. This is the 2nd l-lysine product I've tried (with a few years in between trying). Usually just his left eye is goopy, but when the right eye started getting gunk in the corner I bought this. Of course, I would have been thrilled if both eyes cleared up, but at least the right one eventually did. From the start, Bucky found the flavor of these granules very appealing. I only had to shake them over his wet food and he'd eat it. Did not mix in. Works best if you actually tap the handle of the little dispenser. You have more control over the distribution. We will finish up the container. I won't buy another right away, because I'm not positive if it worked or if it cleared up on its own. Time will tell, but it's worth a try. Attached pictures are from December 2022 and end of Feb. 2023.

5.0 out of 5 stars Very good product, works perfectly for my cat
Reviewed in Australia on December 6, 2022
My cat, Pickles, is a low immune cat. She got sick and eyes infection (chlamydia) very often for the first few month I adopted her. The vet said the chlamydia will come back every now and then and it won’t go away. I looked up what would help, found this product with good reviews and wanted to give it a try. Since I’ve started using this product for about 3 months (one scoop in the morning almost everyday sprinkle on her wet food or mix with a little bit of water in the wet food) she hasn’t got the eye infection at all since. Her eyes clear up and seems so much healthier than before. Will definitely order again. Took about 1 month to arrive from Canada to Australia but worth it. (Hopefully I don’t exaggerate like I thought about all the reviews before)
