Milk thistle (Silybum marianum) has long been used in traditional herbal practices to help support liver function and protect against oxidative damage to liver cells. It contains a powerful blend of antioxidant flavonoids known as silymarin, that help stabilize liver cell membranes, encourage regeneration of liver tissue, and promote the elimination of harmful substances through natural detoxification pathways.

In pets, a healthy liver plays a crucial role not only in processing medications and toxins but also in supporting immune function, hormone balance, skin health, and digestion. Milk thistle is an excellent option for pets recovering from illness, transitioning off medication, or simply needing long-term foundational wellness support. It is also helpful for animals exposed to environmental pollutants, flea and tick chemicals, or processed foods.

Because the liver is interconnected with other systems—including the skin, digestive tract, and mucosal membranes—supporting its function can promote overall balance and resilience throughout the body.
