About Nutra Thrive

Wonderful Supplement!

Product Type: Nutra Thrive for Dogs

We tried this supplement with our two border collie boys, and they both loved it! I love knowing that their bodies are getting everything that they need, especially with how high energy they are. Definitely recommend!

Terrific Terrific

Product Type: Nutra Thrive for Cats

My 16 yr old cat was constantly throwing up. There was nothing physically wrong with her but since giving her NutriThrive the only thing she throws up is an occasional hairball. She is more energetic her coat looks better. My 5yr old is playful and he has more energy if that’s possible. I love this product

Great product

Product Type: Nutra Thrive for Dogs

My big guy, Sven is more active, is shedding less, and his skin has cleared up. We are very pleased. It’s funny, my husband and I each ordered the product at the same time independently. We both knew he needed help.

Wonderful product

Product Type: Nutra Thrive for Dogs

I have a very overweight dog and an elderly very small dog. It was beneficial to both of them. The older one played more after starting on your product. The overweight one got a much shinier coat and energy to run.

Lucky loves the magic powder

Product Type: Nutra Thrive for Cats

Honestly I have not seen my cat be so playful in years since he has been getting the magic powder! He really does love it and just has more energy. He never had a weight problem, more of a digestive issue. This is better than the Purina he has been getting.Thanks so much!

It works!

Product Type: Nutra Thrive for Dogs

Love the product, wish I had started it when our dog was younger. I saw an immediate positive response! His poop became a normal poop again!! I will use it again when we get another pup. Sadly we lost him to cancer. In December
