What's Inside Every Chew
Eight research-backed compounds selected for their ability to support healthy joint function, comfort, and mobility in dogs.
Reishi — Joint Inflammation Support
Contains triterpenes that help support a healthy inflammatory response in joints. Research suggests Reishi may help manage the inflammatory chemicals (TNF-alpha, IL-6) involved in joint discomfort.
Chaga — Antioxidant Defense
Works alongside Reishi to support healthy inflammatory balance from a second pathway. Provides powerful antioxidant protection for joint tissue under oxidative stress.
Turkey Tail — Gut & Immune Health
70% of the immune system lives in the gut. Turkey Tail supports beneficial gut bacteria and healthy immune function — which plays a key role in how the body manages inflammation throughout the joints.
Lion's Mane — Tissue Protection
Provides additional support for healthy connective tissue through antioxidant activity. Helps protect joint structures from oxidative stress while supporting the body's natural repair processes.
Cordyceps — Cellular Energy
Supports cellular energy production in joint tissue. When cells are under stress, they need more energy to function and recover. Cordyceps helps maintain cellular vitality where it matters most.
Maitake — Immune Balance
Supports healthy immune regulation in the joints. Helps the immune system maintain proper balance — so it protects the body effectively without overreacting in ways that affect joint comfort.
Shiitake — Nutrient Delivery
Supports healthy blood flow so nutrients, oxygen, and hydration reach joint tissue effectively. The delivery system that helps bring support to the areas that need it most.
Turmeric (Curcumin) — The Amplifier
A well-researched natural compound that supports healthy inflammatory response through the COX-2 pathway. Also enhances absorption of every other compound in the formula — making each ingredient more bioavailable.
