Six functional mushroom varieties chosen specifically for their beta-glucan content and immune and gut health benefits. 6 Mighty Mushrooms is an incredible full-spectrum liquid extract designed to support the body's normal defenses, digestive balance, and long-term resilience through consistent use.

The strength of this formula is not just that it includes six mushrooms. It is that the blend is built with a clear purpose: support the systems that help pets stay steady from the inside out. Gut health influences immune function. Immune balance influences overall homeostasis. Daily consistency is where that support begins to matter.

Lion's Mane, Reishi, Cordyceps, Shiitake, Turkey Tail, King Trumpet Extracts, Full Spectrum 3:1

Does this work for dogs and cats?

The whole mushroom matters.

We use mushrooms that are grown to full maturity and carefully harvested to preserve the natural compounds found throughout the organism. By working with the complete life cycle of the mushroom, we deliver a naturally balanced profile of nutrients, including beta glucans and other supportive compounds.Quality comes from how the mushroom is grown, when it is harvested, and how consistently it is produced, not from focusing on just one part of the organism.

Austin and Kat was built differently from the very beginning. We are employee owned, female founded, and still led by the same hands that shaped the company from day one. Every formula is made by our own team in our own facility, not handed off to outside manufacturers. The people who craft these products are the same people who bring them home to their own pets, which keeps our standards personal, consistent, and accountable in a way that cannot be outsourced.

Immune Support*

Seasonal Support*

Six mushrooms, carefully extracted for full-spectrum support. This isn’t about packing a label with trendy ingredients. It’s about selecting functional species that work together in a form the body can readily use. Turkey tail provides well-studied beta glucans that help support normal immune function, while lion’s mane contributes naturally occurring compounds associated with cognitive and nervous system health. Reishi offers traditional adaptogenic support, cordyceps helps support cellular energy and stamina, and maitake contributes additional immune-supporting polysaccharides. King trumpet rounds out the blend with unique structural compounds and nutrients that support overall metabolic balance.

This formula reflects a simple principle: when functional mushrooms are thoughtfully combined and extracted using water to preserve their naturally occurring compounds, the result is a balanced, daily-use liquid designed to support resilience, vitality, and long-term wellness.

  • Six functional mushrooms selected for complementary daily support, including nutrient-rich king trumpet
  • No synthetic additives, fillers, or unnecessary extras, just carefully chosen mushroom extracts
  • Crafted in small batches using full-spectrum water extraction for consistent quality and reliability

Who Needs This Formula?

Especially good for pets needing broad, daily wellness support, formulated to help maintain immune balance, digestive function, and overall vitality through a carefully selected blend of functional mushroom extracts. This comprehensive formula benefits pets with changing health needs, animals exposed to environmental or seasonal stressors, and households focused on consistent, whole-body support. Ideal for pets who could benefit from multi-system nutritional support, animals navigating life-stage transitions, and families wanting to build a dependable daily wellness routine. Perfect for supporting pets through routine changes, seasonal challenges, and the long-term maintenance of steady, resilient health.

Science Behind The Scenes

This immune-supporting formula reflects a carefully balanced six-mushroom blend selected to work together across multiple systems that influence long-term wellness. Turkey tail provides naturally occurring beta glucans that help support the body's normal immune responses, while lion's mane contributes compounds associated with nervous system and cognitive function. Reishi brings a long history of use for supporting resilience and overall balance, and cordyceps is valued for its role in cellular energy and daily vitality. Maitake adds additional beta glucans that help reinforce immune readiness, while king trumpet contributes supportive nutrients and naturally occurring compounds that help round out the blend.

This combination is built around the idea that immune health is not controlled by a single pathway. It depends on steady support across multiple systems working together over time, which is why this formula focuses on complementary mushrooms chosen for how they function as a group rather than how any one ingredient performs on its own.
