The Primary Benefit Is: Immune and Organ Support

This formula provides immune and organ support through a blend of natural ingredients designed to work together to maintain normal immune function and organ health in pets.

This approach combines a medicinal mushroom blend with milk thistle, turmeric, burdock, licorice, red clover, ashwagandha and selenium to support immune responses and contribute to liver and kidney health as part of a balanced diet.

What Does Immune and Organ Support Do?

The combination leverages immune-modulating and antioxidant properties observed in medicinal mushrooms and other botanicals, with scientific observations suggesting these ingredients can help the body respond to environmental stressors. Dr. Jeong of a major veterinary university found that mushroom beta-glucans can regulate immune response in animals.

In addition, components such as milk thistle contribute to hepatic health in veterinary contexts, while turmeric and ashwagandha are noted for anti-inflammatory and adaptogenic properties that support normal physiological balance.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
