Harper, the English cream lab - she came to Kat as a puppy and inspired the desire for mushroom-based immune support for growing pups!

Harper's Story

These formulas are dedicated to my dog Harper, who inspired me to explore the benefits of mushrooms.

Harper was my very own quarantine puppy, an amazing distraction from all the chaos happening in the world. As the first developing dog I had taken care of in a while, she inspired me to deep-dive into helping her develop into the healthiest adult she could be. I learned that building a strong immune system was a key to long-term health, and went on a path to discover the power of mushrooms.

Seven mushrooms, countless benefits. This isn't just throwing popular fungi together - it's a carefully researched combination of immune-supporting powerhouses like turkey tail and cognitive enhancers like lion's mane. USDA organic quality meets functional medicine principles in one convenient scoop.

  • Seven organic mushrooms from quality cultivation sources
  • Never any synthetic immune boosters or chemical additives
  • Handcrafted in small batches for maximum freshness
Suggested Use

Especially good for developing pets and immune-conscious families, formulated to help support natural defenses and seasonal wellness through functional mushroom nutrition. This immune-supporting formula benefits young adults, pets with seasonal sensitivities, and animals whose families want to support natural immunity. Ideal for pets who could benefit from adaptogenic support, animals facing seasonal challenges, and households wanting to boost natural defense mechanisms. Perfect for supporting pets through seasonal transitions, environmental changes, and the ongoing development of robust natural immunity as part of comprehensive wellness maintenance.

Formula Science

This immune-optimizing formula represents advanced mycological research through a synergistic seven-mushroom blend designed for comprehensive wellness support. Turkey tail's polysaccharopeptides and beta-glucans provide research-documented immune system modulation, while lion's mane contributes hericenones and erinacines for cognitive and nervous system support. Reishi's triterpenes offer adaptogenic and hepatoprotective benefits, while cordyceps enhances cellular energy production and oxygen utilization. Maitake's beta-glucans support immune system training, chaga provides powerful antioxidant compounds, and shiitake contributes lentinan for additional immune support. This combination recognizes that optimal immune function requires multiple complementary pathways working together to support the body's natural defense mechanisms and adaptive responses.

tiny little bag and no scoop

I received my order today and was surprised to see how small the bag was. I thought ok, well maybe you only give a small amount at each feeding. The directions read "one scoop per 20 lbs". I searched the little bitty bag and finally dumped it into a bowl and there is no scoop. How am I supposed to know how much to give him?

Hi Tami, Apologies for the frustration. We are trying to be a sustainable earth-friendly company so we do not include scoops with our powder supplements. The serving size is 1/2 TSP per every 20 lbs of dog weight. Please let us know if you have any further concerns. -Nicole
