Frequently Asked 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 part of the mushroom you see above ground, while mycelium is the intricate network that grows beneath the surface and supports the mushroom’s growth. Both contain important bioactive compounds, and depending on the mushroom and the specific compound, some may be more concentrated in the fruiting body while others are more abundant in the mycelium.

That’s why we believe in the intelligence of the whole mushroom. Our expertly formulated products use both fruiting body and mycelium to capture a broader spectrum of beneficial compounds, then carefully extract them to create potent, comprehensive mushroom extracts for everyday well-being.*
