VENTURA, Calif. — VetSmart Formulas announced Nov. 22 it has launched a pet supplement, called Critical Immune Defense, to boost immune system health and help them defend against diseases.

The supplement is formulated with four medicinal mushrooms sourced in Asia that are believed to prevent the growth of tumors, including cancerous tumors, lower cholesterol and blood pressure, and reduce inflammation.

Additionally, the formula includes a patented white turmeric extract that could protect companion animals against neurodegenerative diseases, liver damage, cardiovascular risks and arthritis, according to VetSmart.

"We wanted to create a product that would help pets stay healthy and active for years to come. That's why we've spent the past few years perfecting the formula and making sure it includes active ingredients that have been proven to promote normal cell growth and support long-term health in pets,” said Russ Kamalski, founder and CEO and VetSmart.

All ingredients in the supplement are natural. The pet supplements provide antioxidant benefits and are intended for both preventive and remedial use.

"Giving your pets a high-quality antioxidant supplement is highly recommended to further reduce the risk of cancer," added Shawn Messonnier, DVM, founder of Paws & Claws Animal Hospital located in Plano, Texas. Messonnier is also a member of Champion Petfoods’ Transparency Council.

The supplements are manufactured in the US, according to VetSmart. They are available online, direct-to-consumer only through PetWellnessDirect.com.
