General Questions
Functional mushrooms are mushrooms we consume in food, drinks, or supplements for their health benefits beyond basic nutrition. These benefits are backed by both traditional use and modern science.
Humans have used mushrooms for well-being for thousands of years, and modern science now validates these traditional practices. Research shows functional mushrooms can support cognitive health, energy levels, immune function and overall well-being. They also help with stress response, healthy sleep, and provide antioxidant benefits.*
The fruiting body is the mushroom you see above ground - it produces spores (like seeds) and contains concentrated beneficial compounds. Mycelium is the underground network that connects and feeds mushrooms.
All our expertly formulated products are designed to deliver real results, using the most effective form of each mushroom. For some products that means only fruiting body extracts, for others, it means a full-spectrum blend that honors the intelligence of the whole fungi organism, including mycelium.
Unlike other brands that use quickly-grown mycelium, we allow our mushrooms to grow for months before triple-extracting for maximum potency.
