The score explained

evidence, testing and value, weighed before price

Why 5.9 of 10: Provisional: interesting biology, thin human data.

what’s good
  • A few small trials in older adults with mild impairment
  • Well tolerated
  • Reputable mushroom specialist brand
worth knowing
  • Healthy-adult evidence nearly absent
  • Mycelium-heavy products dilute active compounds

what the evidence says

Lion's mane has intriguing lab biology around nerve growth factor and a small number of short human trials, mostly in older adults with mild cognitive complaints, reporting modest improvements that faded after stopping. Evidence in healthy working-age adults is close to nonexistent, and products vary widely in actual active content. Popularity is far ahead of proof.

Plain-language assessment of the human evidence. No cherry-picked citations.
