Most Lion's Mane supplements cut corners. They use cheap mycelium-on-grain (diluted with starch) or fruiting body-only extracts (missing critical compounds).
At Happenstence, we source a full-spectrum dual-extract that includes both fruiting body and lab-grade mycelium — because your brain deserves the complete profile of hericenones and erinacines, not half the story.
This page explains what makes our Lion's Mane extract different, why we fortify it with Vitamin B3 (Niacin), and how manufacturer testing verifies every batch for purity and potency.
Walk into any supplement store and you'll find dozens of Lion's Mane products. But here's what most companies won't tell you: the part of the mushroom they use fundamentally changes what you're actually getting.
Fruiting Body: The visible "mushroom" part. Rich in hericenones and beta-glucans (30%+ in quality extracts). This is what you see growing in nature — the white, cascading mane.
Mycelium: The underground root network. Rich in erinacines, which research suggests are particularly effective at crossing the blood-brain barrier and stimulating Nerve Growth Factor (NGF) production.
Here's the catch: hericenones and erinacines are chemically different compounds. You need both for the full cognitive-support profile that Lion's Mane is known for.
Many cheap supplements grow mycelium on rice or oat substrates, then grind up the entire mixture — grain and all. The result?
At Happenstence: We source lab-grade mycelium cultivated separately from fruiting body extracts. No grain substrate. No filler. Just clean, concentrated bioactives.
A true dual-extract combines fruiting body (for hericenones and beta-glucans) with lab-grade mycelium (for erinacines). Then it uses a two-step extraction process:
Isolates water-soluble compounds like beta-glucans and polysaccharides. These support immune function and cognitive health.
Beta-Glucan Content — Our extract is standardized to contain >20% polysaccharides, primarily beta-glucans.
Cheap mycelium-on-grain products: 5% or less
Isolates fat-soluble compounds like hericenones and erinacines. These are the neuroprotective compounds linked to NGF stimulation.
Hericenones + Erinacines — Both compound classes present due to dual-source material (fruiting body + mycelium).
Fruiting-body-only products: Missing erinacines
Not grown on grain. Cultivated in controlled conditions to maximize erinacine content without starch dilution.
No Rice, No Oats, No Filler — Pure fungal biomass. No grain substrate mixed in.
Mycelium-on-grain products: 40-60% grain starch

Lion's Mane works through multiple pathways — NGF stimulation, neuroplasticity support, and antioxidant activity. Vitamin B3 (Niacin) complements these mechanisms by supporting:
We add 50mg of pharmaceutical-grade Niacin (as Niacinamide) to each serving. This dosage aligns with research on cognitive support without causing the "niacin flush" associated with high-dose nicotinic acid.

We could save money by using mycelium-on-grain like most brands. We could skip the alcohol extraction step. We could avoid fortifying with B3.
But we don't operate that way.
Lion's Mane has centuries of traditional use and emerging clinical research supporting its role in cognitive health. If we're going to sell it, we're going to source it properly:
