What does lion’s mane mushroom actually do, anyway?
You may know it as an ingredient in nootropic supplements. You may have heard of lion’s mane mushroom coffee. You may know it as the big shaggy white mushroom that grows in nature and can look very impressive.
What’s special about it?
The lion’s mane mushroom, or Hericium erinaceus (we mention, as studies we’ll cite often use the botanical name) is an adaptogenic agent that has an established ability to promote nerve regeneration through nerve growth factor neurotrophic activity. In other words, it helps (re)grow neurons.
In a 2023 study, researchers wondered if its abilities (well-established in the peripheral nervous system) would work in the central nervous system too, namely the brain, specifically the hippocampus (responsible for memory).
To boil what they found down to a single line, they concluded:
❝[Lion’s mane extract] therefore acts through a novel pan-neurotrophic signaling pathway, leading to improved cognitive performance.❞

Limitations of the study
It’s worth noting that the above study was performed on mice brains, not those of humans. As there is a shortage of human volunteers willing to have their brains sliced and examined under microscopes, we do not expect this study to be repeated with humans any time soon.
So, are there human studies that have been done?
There are! Particularly promising was this 2020 study of people with Alzheimer’s disease, wherein supplementation with 1g of lion’s mane mushroom daily for 49 weeks significantly increased cognitive test scores compared with a placebo; you can read about it here:
Additionally, this 2019 study showed that taking 1.2g daily for eight weeks helped relieve depression, anxiety, and sleep disorders in overweight or obese patiences:
Are there other health benefits?
It seems so! Unfortunately, most of its other health claims are only supported by animal studies so far, aside from one small study funded by a supplement company for their supplement that contained mostly Agaricus blazei (a different mushroom) with 14% lion’s mane.
However, in animal studies, lion’s mane has also shown promise:
- For digestion
- Against inflammation
- For cardiovascular health
- For diabetes management
- Against cancer
- Against aging
Where can I get it?
