Review: GREAT FOR FELINE HERPES! LYSINE SUPRESSES THE AMINO ACID ARGININE, RESPONSIBLE FOR FLARE UPS!!! - I work w/ my local VSA ( voluntary services for animals). I took in a few kittens that's eyes were almost completely shut with crust & their little noses were covered in crust & mucus. A pitiful site :( . I quickly took all 4 to the vet within 24 hrs. WELL, after they said it was "Feline herpes", (an upper respiratory infection that doesn't go away but can be controlled) IT ended up costing me close to $800!! With Vet costs, testing costs, & the "Wonderfully expensive" medication they gave me for Each cat, That helped some but not much!! They had liquid meds, meds that had to be put INTO their eyes like 4xs a day, & some other antibiotics. It was awful , & seriously it didn't help much at all. It lessened it some, but they needed the meds constantly! I looked on the Internet for any info I could find & found out about LYSINE !! I really thought it was a bunch of "bull" but was willing to TRY anything! I 1st bought a paste & a gel- the cats hated it. I then bought this powder. I mixed it into wet food ( not too much or they taste it!) & they ate it! After a week I noticed all their symptoms were really improving! I had STOPPED the Vets meds as the cost was killing me & not really helping them. After a MONTH all the cats were totally better, no crusty gooey eyes, no crusty nose, sneezing, ALL GONE!! I was amazed!! I studied it more, the use of L LYSINE & it's effects. It surpresses what makes the Herpes virus flare up in the system, so taking it on a Dailey basis means you won't get the flare up & the full blown symptoms! It also works in humans as well. I kept the kittens & have given them forms of LYSINE for 2 yrs now & they have NOT had another flare up since! If I stopped it for a few months, I noticed some sneezing & gunk in their eyes in the 1st year & quickly put them back on it! With 5 cats ( I had a 3 yr old when I took these in, she caught feline herpes from them as well!) it's kinda hard to make sure each one gets 250 - 500 mg Ea. When they eat out of each others bowls! So I just put a scoop into 1 3 oz can of wet, feed them 3 cans & it works great. I tried the TREATS, most cats don't care for them, also many brands you have to give each cat like 10 treats 1-2 x a day! Woa! Or another brand the treats were huge! Only 2 a day because they were the size of a golf ball! Lol. So, the cat powdered LYSINE works good, it's flavored mixes well in food & good to start on. I had no luck putting this on DRY food, I have heard many ppl do that but my cats wouldn't eat the food & most just fell to bottom of dish/bowl. I also bought & use HUMAN grade LYSINE 500 mg tablets & crush them up w/ a spoon & mix into wet food. This is VERY cost effective! It taste stronger than this flavored powder, so use a good wet food to mix with & you wont have a problem. My cats got use to it fast. You can also buy LYSINE powder in BULK on here, it's human grade & already finely crushed up. It works GREAT & cost MUCH less. Plus I like that it's "human" grade. I now can skip months at a time with no LYSINE & they still get no flare ups. This LYSINE is a God send! I recommend this powder if starting out, it's flavored and cats will take it well. But cost wise, the pills, tablets, capsule at your store or on here ( cheaper!) are strongest & the best I've found( crush up finely) . bitter, but cats really don't "taste" bitter I've heard. Either WAY or BRAND you choose it will all but cure your cats of the virus, you won't have huge vet bills & expensive meds that are worthless. 5 cats taking LYSINE on & off for 2 yrs and they have NO MORE SYMPTOMS & are very happy healthy spoiled kitty's... So please do yourself, your wallet, & your cats a favor & put them on a LYSINE regimen of 250 mg a day OR - 500 mg 1-2 x's a day for a flare up or to start off with. Once symptoms subside, you can stay with 250 mg a day to keep them away for good! Btw, In order to replicate & cause FLARE UPS , in humans & cats the herpes virus needs "ARGININE" another amino acid such as LYSINE . when LISINE is taken at higher doses, it prevents the amino acid ARGININE from over producing & hence preventing outbreaks of the herpes virus. So just check your pets FOODS, TREATS etc for any ARGININE ( L-ARGININE ) in them as this will ADD to your problem!! There ARE foods with this in the ingredient list I've found, so just FYI to be safe. Hope this helps someone with the problems I went through & learned from along the way!! :) Jenn ~
Review: A staple for pet lovers - I've had my car on this Lysine for years now and it truly keeps keep his feline herpes flare ups at bay. Even if he has a flare up this keeps them from getting out of control. I keep our other cat on it as well to protect her from his virus and she's free of it. I believe this really helps boost both their immune systems. Our vet originally told us about it and I was so happy to find it on here. Both our cats love the flavor and it smells just like fish - very important as cats depend heavily on their sense of smell for eating. It's super easy to mix in with their wet food and comes with a little scooper inside.

## Questions & Answers

**Q: How much lysine in a "scoop" dose? How many doses in a 100 gram jar?**
A: Hi, according to what it says on the jar, "contains approximately 500 mg of L-Lysine Hydrochloride in a palatable base"  I'm not sure about how many doses in a 100 gram jar (it doesn't say on the jar). I only use it occasionally, so it lasts a really long time for me. They suggest one rounded scoop twice daily. I usually just use one scoop at night in their wet food and it seems to work well enough. The scoop is small, I would guess maybe around 1/8 teaspoon? A very good product at any rate and my cats seem to love the taste and will eat it when mixed in with their wet food. Hope this helps.

**Q: What are the ingredients in Vetoquinol Viralys Powder?**
A: I want to let people who are giving this product to their cats, what hydrolyzed food ingredients are.  Hydrolysis is basically chemical digestion.  The protein, in this case fish & liver, is boiled in sulfuric aced for anywhere from several hours to more than a day to break down the proteins.  Then lye is added to raise the ph back to neutral.  Just what I want to give my cats.  Or not!!!  This is the trouble with buying from the internet.  The full label is usually not available & even when it is, the print is usually so tiny, not to mention blurred,  as to be impossible to read.

**Q: What is the shelf life?**
A: If you buy it from us. To_Your_Health, you will be guaranteed to get the freshest products available.  As of today, December 28, 2015, the expiration date on the containers in stock should be December 2017 or better.  Thanks.

**Q: My cat won't eat wet food & only treats that R crunchy on outside & soft inside. Which might be best chance I have ?**
A: The same maker of the this powdered form of L-lysine also makes this supplement is the form of a crunchy treat and a flavored paste (no affiliation). I recommend (as a vet) 500 mg twice daily to begin with, you can titrate up or down to the most effective dose, but always follow the recommendation of your veterinarian. Also note that l-lysine is most effective against the respiratory/ocular symptoms caused by feline herpes virus, a viral (but not venereal) disease most cats have been exposed to and, just like love, herpes virus lasts forever. The amino acid L-lysine is believed to inhibit the recrudescence of the virus during periods of physiologic stress.

### ⭐⭐⭐⭐⭐ Saved my strays
*by P***P on January 24, 2026*

So I feed the stray cats in my neighborhood but have never actually owned a cat so I didn’t know that they could get sick or get respiratory infections. For about a week when I went to feed them I noticed they were sneezing, wheezing while breathing, eyes just gunky and crazy looking and I had no idea what was happening so I googled their symptoms and found out they had respiratory infections. I ended up purchasing this product in hopes that it would help and oh my gosh they helped so much. After about two weeks each cat that was sick was breathing better, no more eye gunk, and no more coughing and sneezing. I still give it to them like every other day just to ensure they stay healthy but yes, if you’re on the fence just buy it! Totally worth it! Feel like it saved my cats lives to be honest. I mixed it in with soft cat food and then mixed the soft food in with their hard food and just put enough to cover all the cats so even if they weren’t sick I feel it’s still beneficial.
