Details & Benefits

Lysine Complete is now Ultimate Strength Lysine Immunity Health!

Do cats like the taste?

This flavorful and uniquely textured powder was specifically formulated by vets and pet health experts to appeal to even the pickiest of cats. In real-world taste testing, 88% of cats who sampled the delicious chicken-and-cheese-flavored powder preferred the flavor and texture.

We know how hard it can be to convince a cat to eat normal chews, tablets, liquids, or dusty powders. And lysine supplements cant work if your cat wont eat them! Thats why we designed this one-of-a-kind granulated powder. Its easy to give: just use the included scoop to serve in a bowl or mix with a favorite squeeze or crunchy treat.

What is Ultimate Strength Lysine Immunity Health used for?

Ultimate Strength Lysine Immunity Health is a 3-in-1 immune support supplement for cats and kittens, veterinarian-formulated with research-backed ingredients to deliver optimal support for immune and respiratory health. Our unique feline formula targets healthy immunity with three powerful ingredients that work together to support wellness: L-lysine, Prodiet Lactoferrin™, and DMG.

Our lysine supplement for cats helps to support the immune and respiratory systems before, during, and after signs of occasional discomfort, including sneezing, watery eyes, runny nose, and low energy. L-lysine granules may be particularly beneficial for cats with respiratory concerns or seasonal allergies!

What is the right dosage of lysine for cats?

The average lysine dosage for cats is between 250 - 500 mg/day, but that may vary depending on your veterinarians recommendation and your unique cats health and history. Some cats require a stronger dose of lysine to get the support that their immune and respiratory systems need.

Ultimate Strength Lysine Immunity Health offers 1000 mg/day of high-quality l-lysine for advanced support for adults. Half the dosage (500 mg/day) is recommended for kittens aged 3-6 months. For kittens under 3 months old, please consult your veterinarian.

When using a lysine supplement, it may take up to a few weeks to enjoy the full benefits, but some owners report seeing small positive changes within just a few days.

If youre looking for a lower-dose lysine supplement for cats, Lysine Immunity Health offers 250 mg of l-lysine per serving and comes in small, fish-shaped chicken-liver-flavored soft chews.

    I will always use this product for my cat

    I have an extremely picky cat and out of 10+ products I have tried this is the only one he will happily take. Other lysine products pail in comparison making him Unsymptomatic, heightened energy levels, and his breathing sounds much clearer. I also notice he doesn't get as dry of skin on this as he did taking other brands. Definitely would recommend!

    Made my cat sick

    Even at a half dose to start my poor cat threw up two entire meals after she got this in her bowl. Not good.
