Are any of the ingredients sourced from China?

PetHonesty does not source anything from China. All of their ingredients are sourced from the USA with the exception of Kelp from Iceland and Turmeric from India.

Will this also help with bad dandruff?
Answer by ChewyFeb 10, 2022
Lysine Immune Health+ does not help with dandruff since it helps support immune health, skin and eye health, and allergy symptoms such as congestion, sneezing, wheezing, itching, squinting, and eye and nose discharge.

Will not eat

My cat would not touch her food after I mixed in a 1/2 a scoop into her wet food she usually eats. I tried a couple times. When will companies realize their so called flavorings do not fool cats? Can the make anything without flavor additives so you can get it in your pets that need the supplements and medications? I even get my vet medications done at expensive compounding pharmacies and the flavorings do not work well at all and are very inconsistent if you do finally get your cat used to one. Since many cats have herpes I really wish something could be created that will actually help them.

It's Perfect!

I needed a way to get Lysine into my cats. I came across this powder that has chicken and tuna flavor! It comes with a teeny scoop which makes it so easy to add to food. My cats don't mind it AT ALL. Like they don't even notice it's there.

Worse Lysine Ever!

My cats hate this stuff! They won't eat with this in their food. Wasted several cans of wet food. Smells horrible as well! Don't buy it!

Healthy Product

This is a healthy product, I only put a little bit of the power for the first time and mixed with wet cat food. My cats ate it but the second time, they don't want it anymore. I noticed their stool were soft after they tried it the first time.

very good formula

I needed this for one of my cats with caughing. He's just not eating it very well due to his decreased smelling ability. I believe in the product and will probably order more when this container is used up.

Lysine is key to healthy

As the cat coordinator for a rescue in Midlothian Tx I swear by Lysine to boost immune system or our kittens & cats. Animals, just like humans, have issues with air quality. They get nasal congestion, sneeze just like us. Sprinkle on wet or dry food. It’s tasteless and gives them a boost!
