  • General Questions
What are functional mushrooms?

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.

What are the health benefits of functional mushrooms? 

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.*

What's the difference between fruiting body and mycelium? 

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.

Can these mushroom products treat or cure specific medical conditions or diseases? 

Our product information has not been evaluated by the FDA and the products are not intended to diagnose, treat, cure, or prevent any disease. We cannot provide medical advice. Please consult your healthcare provider or a certified herbalist about using mushrooms for specific health concerns.

Can I take your products while pregnant, breastfeeding, or give them to children?

Our products are formulated for adults and are not specifically tested for use during pregnancy, breastfeeding, or in children. While many of our ingredients have a long history of traditional use, we always recommend consulting with your healthcare provider before starting any new supplement if you are pregnant, nursing, or considering use for a child.
