we ♡ mushrooms

Functional mushrooms aren’t a trend for us. They’re something we began incorporating into our own pack’s routine years ago. What started as curiosity turned into conviction. Today, they’re one of the most powerful tools we use for immune balance, vitality, and everyday resilience.

Over time, mushrooms became part of our everyday rhythm. Not because of one dramatic moment, but because they aligned with how I think about health. They felt like something my dogs should take not just when something is wrong, but because I want to keep things right.

As the company grew, I kept thinking how do we bring mushrooms into other things we make? If mushrooms were part of how I supported my own pack, they needed to meet the same standards as everything else we formulate.

we've partnered
with the best

As mushrooms became a core part of how I support our own dogs, it was important to find a partner that approached them with the same level of care.

We chose M2 Ingredients, North America’s largest grower of functional mushrooms, because of their commitment to transparency, controlled cultivation, and science-based extraction. They focus on measurable beta-glucans and consistent quality, not marketing claims.

Their ingredients are the foundation of our mushroom line, and they give us confidence that what we’re formulating with is clean, traceable, and thoughtfully produced. That matters to me.

not all mushroom extracts are created equally

Your pet deserves more

Quality varies widely depending on how mushrooms are grown, extracted, and tested. That’s why we sought out partners producing high-quality mushroom extracts and built our formulas around ingredients we would feel confident giving our own pets every day. The difference in sourcing and processing can make a meaningful difference, and we believe your dog deserves that level of care.

Extracts that deliver

Mushrooms contain beneficial compounds within tough cellular structures that must be properly extracted to make them available. Without proper extraction, much of the value can remain locked inside the mushroom material. That’s why we use mushroom extracts designed to concentrate the naturally occurring compounds associated with immune and wellness support, helping ensure your dog receives meaningful nutritional value in every serving.

Grown with intention

The quality of a mushroom extract starts long before it becomes an ingredient. Growing conditions, substrate, and harvesting methods all influence the compounds mushrooms naturally produce. We prioritize mushroom ingredients grown in controlled environments and harvested at the right stage to preserve their naturally occurring beta-glucans and beneficial compounds.

Crafted our way

We believe quality should never be an afterthought. That’s why every formula we create is developed with careful attention to sourcing, formulation, and production. From selecting trusted ingredient partners to producing finished formulas at our Seattle Makery, our goal is simple: make supplements we feel confident giving our own dogs every single day.

MUSHROOMS MAKE THE DIFFERENCE

Immunity*
Digestion*
Cell Health*
Gut support*
Cognition*

Functional mushrooms are different from most ingredients because they support the body’s natural systems rather than targeting a single outcome. Their naturally occurring beta-glucans, polysaccharides, and antioxidants help support immune balance, digestive health, and cellular protection.

For centuries, mushrooms have been valued for their ability to support resilience and everyday wellness. Today, modern research continues to explore the role these compounds play in maintaining healthy biological function.

  • Rich in beta-glucans that help support balanced immune activity
  • Provide antioxidants that help protect cells from oxidative stress
  • Traditionally used to support digestive health + a balanced gut
  • Support cognitive function and overall vitality


Why functional mushrooms?

Functional mushrooms have a long history of use in traditional wellness practices and are increasingly studied for the unique compounds they naturally contain.

Beta-glucans help support balanced immune activity, antioxidants help protect cells from everyday stress, and other compounds may support digestive and cognitive health.

Rather than acting like a single isolated nutrient, mushrooms provide a complex matrix of naturally occurring compounds that help support multiple aspects of health as part of a daily wellness routine.

powders vs. liquid extracts

Whole mushroom powders offer a natural, minimally processed option with the full fruiting body.
  • Whole fruiting body nutrition
  • Rich in dietary fiber and nutrients
  • Versatile for cooking and supplements

frequent asks about fungi

Functional mushrooms are species of mushrooms that have traditionally been used to support overall wellness. They contain naturally occurring compounds like beta-glucans, polysaccharides, and antioxidants that help support healthy biological function.

Different mushroom species provide different types of beneficial compounds, which is why many formulas include more than one mushroom.

Functional mushrooms are often used to help support immune balance, digestive health, cellular protection, and cognitive function.

Because mushrooms contain a range of naturally occurring compounds, they are often used as part of a daily wellness routine to help support overall vitality rather than targeting just one system.

Yes. Many functional mushroom species have a long history of safe use in animals and are commonly included in pet supplements.

As with any supplement, quality and sourcing matter. Using properly grown and processed mushroom ingredients helps ensure safety and consistency.

Mushrooms naturally contain beneficial compounds within tough cellular structures. Proper extraction helps release and concentrate these compounds so they are more available when consumed.

This allows mushroom extracts to provide consistent levels of the compounds associated with immune and wellness support.

Functional mushrooms are typically used as part of a daily wellness routine. Because they support normal biological function, they are generally intended for consistent use over time rather than immediate effects.

Many pet parents choose to include mushrooms as part of their dog’s long-term health routine.
