Lion's Mane Research is a Mess

Welcome to my first video! I was working the past couple months on understanding more about what in Lion’s Mane actually helps people, and I found the answer to be a lot more messy than expected. This is a long one, so below is a summary of what I spoke about. But for those with the time, I hope you enjoy!

Some Housekeeping:

To support Badwater, consider using this link to purchase from our affiliate partner, North Spore. From liquid cultures to custom jar lids, they have provided me nearly all the tools I still use for growing mushrooms. They’re great quality, have super customer support (they’ve had a no-questions-asked policy whenever I have a random issue), and I think they are perfect for anyone getting into mushroom growing or who want to upgrade their DIY gear. All quality. This is the humidity tent that I use to grow my Lion’s Mane.

A Summary of this Mess of Research

Hericenones (Fruiting Body) vs. Erinacines (Mycelium)

• Hericenones are found in the fruiting body and believed to stimulate nerve growth factor (NGF).

• Research suggests hericenones do not cross the blood-brain barrier in vivo, making their cognitive benefits uncertain.

• Erinacines, found in the mycelium, have been shown to cross the blood-brain barrier and directly promote NGF synthesis.

• Erinacines appear to have stronger therapeutic potential for neuroprotection and cognitive health than hericenones.

Scientific Uncertainty and Conflicting Findings

• Studies confirm Lion’s Mane fruiting bodies do have cognitive benefits, but often fail to identify the exact compounds responsible.

• Some research supports mycelium-based supplements due to erinacines, while others show fruition body extracts are beneficial, but not necessarily due to hericenones.

• The lack of consistent compound isolation makes it difficult to determine the most effective form of supplementation.

Challenges in Research and Industry Controversy

• Many studies misinterpret or oversimplify findings, leading to misinformation about which compounds are effective.

• The industry is split between:

  • Whole biomass (mycelium + substrate) advocates (e.g., Paul Stamets)

  • Fruiting body extract proponents who argue for alcohol or hot water extraction.

• More research is needed to isolate and confirm which compounds provide the greatest cognitive and neuroprotective effects.

We are overly-focusing on Hericenones and Erinacines as the two primary cognitive enhancers found in Lion’s Mane, while overlooking numerous other active compounds that might hold the key to explaining the benefits of Lion’s Mane fruiting bodies.
