Happy Harvest Corporation is established in 2003 in Taiwan.

As the significant development of veterinary medicine, pets live longer, and we are happy that we now have more time with them. However, at the same time, more pets are suffering from diseases and illness that come with ageing and modernized life, such as stomatitis, allergy, asthma … These are usually chronic illness that needs long-term caring.

We believe that with research, we can find natural ingredients that help our pets combating their chronic illness and might even help to reduce the use of pharmaceuticals, which may cause negative side-effects. We are pet parents ourselves, and we stay close to veterinarians. We listen to vets’ experience and their needs in current clinical treatment. We work with Veterinary schools, laboratories, and experienced vets to find the best and science research proofed nutraceuticals.

Our caring sales and technical team are always passionately aiming at helping animals, and veterinarians access the best valuable clinical health support.

Our mission is to help veterinarians and pet parents bringing their pets longer, happier and healthier lives.
