Lion's Mane
Hericium erinaceus — fruiting body
What "fruiting body" means, and why we stop there.
Most lion's mane sold as a supplement is not, in any meaningful sense, lion's mane.
It is mycelium — the fungal root structure — grown on a bed of rice or oats, then dried and ground whole, hull and all, into powder. The mushroom itself, the white cascading structure that gives lion's mane its name, is never part of the process.
We grow ours differently. Our lion's mane is cultivated in San Diego, California, and harvested as fruiting body only. It is the more costly way to grow a mushroom, and the slower one. We consider that the point, not the obstacle.
Grown, not grafted. Harvested, not filled.
A tonic, taken in practice — not a remedy for a moment.
In East Asian herbal traditions, lion's mane has long been prepared as both food and tonic, valued for its place in a daily practice rather than reached for as a remedy for any single condition. It was cooked, brewed, and shared — a part of how a day was built, not an intervention in how a day went wrong.
Contemporary interest has followed the same shape. Lion's mane is traditionally used to support cognitive clarity, memory, and nervous system wellness. This is a description of how the mushroom has been used, and continues to be studied, in that context — not a claim that it treats, cures, or prevents any condition.
Historically, it was prepared as a tea, folded into soups, or cooked in stir-fries — a food as much as a tonic. That's still how we think about it: something you return to, not something you reach for once.
Traditional and modern preparation.
Traditional: Brewed as tea, or added to soups and stir-fries in Chinese and Japanese culinary practice — part of a daily rhythm rather than a response to a single symptom.
Modern: Stir the powder into a smoothie, coffee, or warm water. Take capsules with a meal or a full glass of water.

Common questions on lion's mane.
How much lion's mane is in I AM Vitality?
The powder delivers 400mg of lion's mane fruiting body per ¾ tsp serving. The capsules contain 250mg per capsule.
What's the difference between fruiting body and mycelium-on-grain?
Fruiting body is the mushroom itself, harvested and dried. Mycelium-on-grain is the fungal root structure, grown on rice or oats and ground whole — often diluting the mushroom content with leftover grain. Ours is fruiting body only.
Can I take lion's mane if I'm pregnant or nursing?
Speak with your healthcare provider first. There isn't sufficient safety data for us to make a recommendation either way during pregnancy or nursing.
How should I store it?
Keep the powder or capsules in a cool, dry place away from direct sunlight, and reseal the lid tightly after each use.
Will lion's mane interact with my medication?
If you take prescription medication, talk with your healthcare provider before adding lion's mane, or any new botanical, to your routine.
Is lion's mane an adaptogen?
Not technically — it's classified as a functional mushroom. Adaptogens like maca and bacopa are a separate botanical category, though both are traditionally used as part of the same daily wellness practice.
