Lion's Mane vs Urolithin A

Side-by-side of Lion's Mane and Urolithin A. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.

Effects at a glance

Lion's Mane

  • Edible medicinal mushroom containing NGF-stimulating hericenones and erinacines
  • Mori 2009 trial (n=30) in mild cognitive impairment showed cognitive improvement at 3 g/day for 16 weeks, reversing 4 weeks after discontinuation
  • Saitsu 2019 (n=31) in older adults reported MoCA improvements at 3.2 g/day over 12 weeks
  • Multiple small mood trials suggest reduced anxiety and depression scores at 1 to 4 g/day extract
  • Mechanistic case rests on NGF stimulation and remyelination support; in vivo human NGF measurement is absent
  • Product quality varies substantially; mycelium-on-grain products can be over 50% grain by weight

Urolithin A

  • Gut-microbiome-derived metabolite of pomegranate and walnut ellagitannins
  • Roughly 40% of adults are 'urolithin producers' from dietary intake; ~60% are non-producers
  • Ryu 2016 (Nature Medicine) reported lifespan extension in C. elegans and muscle benefits in aged rodents
  • Andreux 2019 first-in-human trial (n=60) established safety and mitochondrial gene-expression upregulation
  • Singh 2022 (n=66, 4 months, 1000 mg/day) reported improved muscle endurance in older adults
  • Most human trial portfolio is Amazentis-funded; independent replication is thin

Routes oral oral
Onset (hr) 168 2
Peak (hr) 1344 4
Molecular weight - 228.2

Mechanism Hericenones and erinacines stimulate NGF mRNA expression and NGF protein release in cultured neurons; secondary anti-inflammatory and remyelination-supportive activity in preclinical models. Induces mitophagy via potentiation of PINK1/Parkin signaling, leading to selective degradation of damaged mitochondria. Secondary anti-inflammatory effects via NF-kB modulation.

Which Should You Take?

Urolithin A comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-A outcome catalogued. Lion's Mane is the right call when one of the conditionals below applies.

  • If your priority is focus or working memory, pick Lion's Mane.
  • If your priority is nerve health, pick Lion's Mane.
  • If your priority is healthspan extension, pick Urolithin A.
  • If your priority is muscle hypertrophy, pick Urolithin A.

Default choice: Urolithin A. Lower friction to source, a Tier-A evidence outcome catalogued, and broader goal coverage. Reach for Lion's Mane only if your priority sits squarely in the goals it owns above.
