    Hello! I see a lot of people recommending Lysine supplements for feline herpes (in our case, manifested as bad eye problem -- which is being treated). Would love any feedback on this. Thank you.

    There apparently are studies that show lysine doesn't do anything--

    however, in my experience at home and when I was with the rescue, it does seem to help. I use the human lysine powder because it's a lot cheaper. About 1/4 tsp twice daily.

    I have found it works. When I adopted MurrFee he had weepy eyes. I first used eye antibiotic and it cleared it up but the weeping reappeared when I stopped. After two routs of antibiotics I tried L-Lysine and that clear up the eyes. I give L-Lysine to all my cats.

    I’ve found the same as above. We never will know if it just went away or the lysine worked but I ne Er found it hurts.

    I did read a study showing that it was ineffective in shelter cats, though I believe overcrowding/stress exacerbates the problem so I suppose in a home setting results may be better.
    I was using Now Pets L-Lysine Powder for my kitten which didn't help but after running a PCR Resp IDEXX Panel we discovered she didn't have herpes at all (she had 3 other viruses but not herpes) so that's something to keep in mind in case an actual panel hasn't been run to confirm the virus.
