Comparison
Citicoline vs Lion's Mane
Side-by-side of Citicoline and Lion's Mane. 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.
Citicoline
Citicoline supplement profile: CDP-choline as a phosphatidylcholine precursor, Cognizin dosing 250-2000 mg, cognition trials, stroke recovery evidence.
Lion's Mane
Lion's mane mushroom (Hericium erinaceus) supplement profile: hericenones and erinacines stimulate NGF in vitro. Human cognition trials are small.
Effects at a glance
Citicoline
- •Choline donor and phosphatidylcholine precursor; oral bioavailability roughly 99%
- •Standard prescription medication for stroke recovery and vascular cognitive impairment in much of the world
- •Healthy-adult cognitive trials (Cognizin) report small gains in attention and working memory at 250 to 500 mg/day
- •ICTUS trial (n=2,298) was negative on stroke recovery in the modern thrombolysis era
- •Lower per-gram choline content than alpha-GPC (~18% vs ~40%), meaning smaller TMAO load at equivalent dose
- •Long uridine half-life (~56 hours) supports once or twice daily dosing
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

| Molecular formula | C14H26N4O11P2 | mixed extract |
| Mechanism | Hydrolyzed to cytidine and choline after absorption; both cross the blood-brain barrier and are recombined intracellularly to reform CDP-choline, supporting phosphatidylcholine synthesis and acetylcholine production. | Hericenones and erinacines stimulate NGF mRNA expression and NGF protein release in cultured neurons; secondary anti-inflammatory and remyelination-supportive activity in preclinical models. |

Which Should You Take?
Citicoline and Lion's Mane score evenly on the criteria we weight (goal breadth, legal accessibility, evidence depth). The conditionals below should drive the decision more than any aggregate score.
- → If your priority is stroke recovery, pick Citicoline.
- → If your priority is choline supply, pick Citicoline.
- → If your priority is nerve health, pick Lion's Mane.
- → If your priority is mood, pick Lion's Mane.
Edge case: Half-lives differ materially (Citicoline ~56 hr vs Lion's Mane ~6 hr). Citicoline reaches steady state faster; Lion's Mane is easier to dial in if tolerability is uncertain.
Default choice: either is defensible. Citicoline edges out on goal breadth + legal accessibility; Lion's Mane is the right call if your priority sits in the goals listed above.
