Product Description

Two of nature's most studied functional mushrooms, grown in California and blended for daily canine support. Lion's Mane supports cognitive function and healthy brain aging, helping maintain the mental sharpness that keeps them learning, playing, and finding the ball. Cordyceps supports natural energy, stamina, and a resilient immune system. Grown on organic oats with no fillers, no preservatives, and nothing artificial. 

The clean details:

  • Grown in the USA (California) on organic oats
  • Full-spectrum: mycelial biomass and fruit body
  • No added fillers, colorants, preservatives, or desiccants
  • Free of all nine major food allergens

Ingredients

Ingredients: Mushroom powder blend cultured on organic oats (Avena sativa), containing:

  • Organic Cordyceps (Cordyceps militaris) – mycelial biomass, stroma, and fruit body
  • Organic Lion's Mane (Hericium erinaceus) – mycelial biomass and fruit body

Problem?

Dogs slow down mentally and physically as they age. Senior dogs especially can lose sharpness, energy, and immune resilience, and most dog foods do nothing to address it.

Quick Summary

Two functional mushrooms, one daily scoop. Supports cognition, energy, and immune defense for dogs at every stage, made in the USA with zero fillers.

What It Is

A two-mushroom powder blend of organic Lion's Mane and Cordyceps, grown in California on organic oats. No fillers, no preservatives, nothing artificial.

Why It Works

Lion's Mane is the most studied mushroom for cognitive and nerve support. Cordyceps supports stamina and immune function. Full-spectrum sourcing (mycelium and fruit body) preserves the beneficial compounds, including naturally occurring beta-glucans.

Who is it for?

Senior dogs staying sharp, active dogs that play hard, and any pup whose owner wants daily brain and immune support in one clean scoop.

How to Use

Sprinkle over food once daily at mealtime. Dose by weight per the chart on the label. Safe for daily, long-term use.

2-year shelf life. Store sealed in a cool, dry place.
