Comparison
Lion's Mane vs Omega-3 (EPA/DHA)
Side-by-side of Lion's Mane and Omega-3 (EPA/DHA). 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.
Lion's Mane
Lion's mane mushroom (Hericium erinaceus) supplement profile: hericenones and erinacines stimulate NGF in vitro. Human cognition trials are small.
Omega-3 (EPA/DHA)
Omega 3 fish oil profile: EPA/DHA marine fatty acids, 2-4 g/day cuts triglycerides 20-30%, REDUCE-IT showed 25% cardiovascular risk reduction on icosapent eth.
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
Omega-3 (EPA/DHA)
- •Reduces fasting triglycerides 20-50% at 2-4 g/day in hypertriglyceridemic patients
- •REDUCE-IT showed 25% relative risk reduction in major CV events at 4 g/day icosapent ethyl
- •Modest antidepressant effect (SMD ~0.40) for EPA-dominant formulations at 1-2 g/day
- •Atrial fibrillation incidence rises ~30-50% at 4 g/day; relevant for older patients with pre-existing CV disease
- •Tissue omega-3 index (RBC EPA + DHA) target ~8%; Western baseline typically 4-5%
- •Triglyceride and re-esterified triglyceride forms absorb ~70% better than ethyl esters in fasted state

| Molecular weight | - | 302.45 |
| Molecular formula | mixed extract | C20H30O2 (EPA); C22H32O2 (DHA) |
| 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. | Substitutes arachidonic acid in membrane phospholipids, shifting eicosanoid production toward less-inflammatory 3-series prostaglandins and 5-series leukotrienes. Activates PPAR-alpha to lower hepatic VLDL/triglyceride synthesis. DHA modulates synaptic membrane fluidity and neuronal function. |

Safety profile
Lion's Mane
Common side effects
- mild GI upset
- occasional skin rash
- contact dermatitis (rare)
Contraindications
- mushroom allergy
Interactions
- anticoagulants: theoretical antiplatelet effect, no documented clinical events(minor)
Omega-3 (EPA/DHA)
Common side effects
- fishy aftertaste
- eructation (fish burps)
- mild dyspepsia
- loose stools at high doses
Contraindications
- fish allergy (use algal omega-3 alternative)
- active bleeding disorders
- scheduled surgery (discontinue 5-7 days prior)
Interactions
- warfarin and DOACs: additive antiplatelet effect at 2+ g/day; meaningful bleeding risk(moderate)
- aspirin and antiplatelet agents: additive bleeding risk at high doses(moderate)
- statins: complementary cardiovascular effects; no pharmacokinetic interaction(minor)
- antiarrhythmics: high-dose omega-3 increases AF risk; relevant in pre-existing arrhythmia(moderate)
Which Should You Take?
Omega-3 (EPA/DHA) 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 nerve health, pick Lion's Mane.
- → If your priority is mood, pick Lion's Mane.
- → If your priority is cardiovascular health, pick Omega-3 (EPA/DHA).
- → If your priority is healthspan extension, pick Omega-3 (EPA/DHA).
Edge case: Half-lives differ materially (Lion's Mane ~6 hr vs Omega-3 (EPA/DHA) ~48 hr). Omega-3 (EPA/DHA) reaches steady state faster; Lion's Mane is easier to dial in if tolerability is uncertain.
Default choice: Omega-3 (EPA/DHA). 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.
