Healthy cat, happy cat mom!
I was using a more expensive brand but Iâm very happy with this product. The price and quantity is the best Iâve found.My cat is FELV+. Itâs vita to keep his immunity system up. I feel this product has helped keep him healthy, he has not been sick once, and the vet told me a few days ago he looked great and was very healthy so Iâm grateful this product works!

My cats take it with no problems 🙂
My catâs vet recommended me to buy L-Lysine for my cats when they were kittens. It works well. I donât recommend feeding it to your cat every day unless directed by a professional.I mix this with my catâs wet food. They eat it with no problems , so Iâm guessing it tastes fine. There is no smell to it. I know itâs helping my cats because they heal up better with this than the prescriptions they receive.I am very thankful for this product because it saves me time and money.This product was packaged well, I had no issues, and shipment came in time. I will purchase more when I need more and will continue to be a loyal customer to this brand and seller.

Huge pill for small dogs, wish I had known.
***Two Month Update***Our little girlâs itching is virtually gone, just the normal scratch here and there. Her hair is much softer and even her skin looks the best Iâve ever seen it.When searching for a supplement to help my nine year old Pomeranian who had suddenly started showing signs of allergies or dry skin/hair due to loss of Omega-3âs. I came across NOW Pets Omega-3 supplement and knowing how I value and trust NOW Foods it was a no brainer to purchase this product, especially after reading the product details.Now a little background.Lucy is a nine year old Pom that came to our family as a rescue at about one year old. She joined our other Pom of the same age who was on a diet of Salmon dog food. Everything went great for seven and a half years then two things happened. We had to say goodbye to our little boy due to cancer and my husband decided on a fresh dog food whose only selections were Beef, Chicken or Turkey. Six to seven months later Lucy started itching and biting herself and tore her skin up right proper. We got her healed and she started digging really bad again after a week to two weeks. I ordered Amazonâs liquid Salmon supplement/topper and she refused to touch it or any food it came in contact with. I found that strange since my older Pomeranianâs loved it.Lucyâs itching and digging started up bad angain and I looked for other solutions online and found NOW Pets. Lucy takes pills very well and after I compared prices I decided to purchase on Amazon due to quick and free shipping with Prime.I was shocked by the size of the capsule when it arrived (picture attached shows the capsule next to a AA battery). Itâs a horse pill, larger than a lot of human pills Iâve seen and my little Lucy is not even nine pounds. Itâs a real chore trying to get her to swallow a pill basically the size of her mouth.I donât know if I looked over the size written in the description but upon reviewing images before writing this review I did not see any visual representation of the size as other supplements do on their product pages. It appears to be a high quality product that I expect from NOW but I would have ordered something smaller if I had known the capsule size.As far as its effectiveness it is too early to tell other than after two days her itching was cut in half. Her hair is still really stiff and ragged looking, nothing like the fluffy furbaby sheâd been for eight years. I expect ber hair to take a while to recover.To compensate for the size of the capsule Iâve started piercing it and allowing the liquid to be mixed in to her food. When the capsule is pierced the smell is overwhelming and a put off for my little girl. Apparently it tastes ok because unlike the Amazon brand the food with the liquid from the capsule was eaten as normal after nosing around the bowl to determine if it was her normal food.Iâll update this post as time progresses with coat changes, shine, softness and shedding.

Good formula
I do believe this is a good formula for the right dogs. Unfortunately, I have a dog that is sensitive to too many things, including this. I do like Now brand products for myself and trust them.

Stops the kitty sneezes
My kitty was getting sneezy so I bought this to try and stop it. It worked! I mixed it in with some Churu and he ate it up without any problems. A serving is pretty tiny so this bottle will last me a long while too.

Works on dogs, doesn’t works on cats
So, My dog eat it, i mixed the pill with some meat, he in fact got very relaxed but dont know if it Will work for mor stressing times like fireworks or vet appointments. Be aware, the smell is too strong and My cat rejected, i tried mixing with his favorites foods but nothing worked, too strong. I gave him a little but didnt make any difference in his behavior

This is a great deal!
This is a great deal! Honestly, with all the brands out there, I just purchased this because it was the cheapest. I just wanted to give a sick stray some immunity help. This item actually recommends to be given TWICE A WEEK, not everyday like some others, and the dose is 1/8 of a teaspoon which is 276mg of L-Lysine… That’s like just a pinch of salt. (Unless, you have been directed to give a higher dose.) This bottle is also not small. It is like the size of a human vitamin bottle. This bottle will probably last forever and I’m thinking of donating most of it to a cat rescue.I give this to a sick adopted outdoor cat, a healthy stray cat, and to my healthy, but aging, strictly indoor cat …with no problems. They seem to not notice it at all in either wet food or kibble.

The product seems good enough however, itâs unfortunate that my dog wonât eat them! It seems that he just doesnât like the flavour. I even tried crushing & mixing it into his wet food-he wouldnât eat it. Too bad we wonât ever find out whether it works to alleviate his allergy symptoms! Maybe weâll try peanut butter…

Excelentes resultados no pelo da minha Yorkshire!!!

I almost never write product reviews, especially on Amazon. So this is a testament to how well this stuff works.I have an exotic shorthair. Flat face, goopey eyes even on the best of days, trouble breathing, etc. My cat also seems to have almost no sense of smell probably because she has tiny nostrils and respiratory issues – this means she eats only one type of particularly pungent kibble, no interest in any of the 20+ different treat brands I’ve got her, no interest in wet food, no interest in any human food.I do not agree with the breed, she was a rescue and really is the sweetest cat ever. Her life has been difficult because of her breed specific issues.I’ve had her on this for around 2 weeks and the difference is astounding. I haven’t had to wipe her face at all this week, very little goops (nothing she can’t groom off herself), her breathing is way better, and she is taking an interest in other food and sniffing EVERYTHING. I’m shocked. I assumed this would help a bit but she really seems so much more lively and happy. She’s acting like an actual cat, playing and running around (which would have tired her out way quicker before), doing cat things she hasn’t done before.I’ve had her for 2 years and I’ve never seen her like this. YMMV of course, and I can’t tell if the results will last long term. But I am very satisfied with this purchase.Also great value. No scoop is included but it’s only a 1/8 tsp twice a week sprinkled over her food. This will last easily a year+. She hasn’t turned her nose up at it yet so I don’t think she notices it’s there.Definitely worth a try. Especially if you have a brachycephalic cat breed (flat face).

My Yorkie hates the taste of it. But more than that, this product is not making her calm at all, instead, itâs making her restless. Sheâs alert at all times, growling at the door after every little sound… I wasted my money…

Having spent 2K on seeing 5 vets over four months, this appears to have massively reduced my cat’s drippy nose and sneezing and she can now obviously smell more, and as a result, is less of a fussy eater. The vets reached the point where they could offer no more help, other than perhaps a referral for a CT scan, etc. but as my cat was basically otherwise well, and she chooses to remain indoors, this felt unnecessary. We did agree to an anaesthetic and nasal camera, which reassured us that polyps/growths appear unlikely, so before going down that route, I would thoroughly recommend giving this a try. Within 5 days of just a teeny amount in her food, once a day, there was a massive improvement.
