FieldbornLion's mane: fruiting body or mycelium?
By George · 2026-10-25
Lion's mane products are made from either the fruiting body (the mushroom you can see and pick) or the mycelium (the root-like network), usually grown on grain. The two contain different compounds, but both are sold as 'lion's mane'.
Why it matters
Mycelium grown on grain is harvested together with the grain, so the powder can be mostly starch. Fruiting body products avoid that. Read the label for the words 'fruiting body' and ask for a beta-glucan test.
Where it comes from
Most lion's mane on the market is grown in China. Demand for lion's mane and turkey tail is outrunning quality supply, which makes them targets for adulteration.
What we use
Our launch product is an organic fruiting body extract from Nammex in British Columbia. We're setting up a grow room at Mt. Uniacke, Nova Scotia, and we'll film every step.
