Lion's Mane Mushroom Extract
A genuinely single-ingredient Lion's Mane extract, sourced exclusively from the fruiting body rather than mycelium grown on grain, with a disclosed beta-glucan standardization rather than an inflated total-weight figure.
Performance & Focus
120 capsules
2 capsules
CURATEDFIT SUMMARY
Passes because this is extracted specifically from Hericium erinaceus fruiting bodies, not mycelium grown on grain substrate, a distinction that matters more than it might sound. Most Lion's Mane products on the market use mycelium-on-grain, which lets a label claim a large total milligram figure while a substantial portion of that weight is grain starch rather than mushroom material, inflating the apparent dose without inflating the actual active compound content. This product is standardized to a minimum of 25% beta-glucans, a verifiable marker rather than an unspecified total weight, and the ingredient list contains nothing beyond the extract and the capsule shell itself.
WHAT IT IS
A vegetarian-format capsule providing 500 mg of Lion's Mane Mushroom Extract (Hericium erinaceus fruiting bodies) per capsule, standardized to a minimum of 25% beta-glucans, with a standard two-capsule daily serving delivering 1,000 mg total.
WHO IT IS FOR
Someone specifically wanting the nerve growth factor (NGF) stimulation and neurogenesis mechanism behind long-term cognitive support, and who wants to avoid the mycelium-on-grain dilution issue common across this specific ingredient category.
INGREDIENT BREAKDOWN
Lion's Mane Mushroom Extract (Hericium erinaceus, Fruiting Bodies, std. to min. 25% Beta Glucans)
1,000 mg (2 capsules)
Fruiting body extract, single marker standardization. Sourced exclusively from fruiting bodies rather than mycelium-on-grain, which is the more common and less transparent production method across this ingredient category. Beta-glucans are the standardization marker used here, a legitimate and verifiable compound class, distinct from the inflated total-weight claims (2,000 mg, 4,000 mg-plus) common on products that don't disclose fruiting body versus mycelium sourcing.

TRANSPARENCY NOTE
The single most important thing to understand about this product is what it isn't: mycelium grown on grain. That distinction is the central quality issue across the entire Lion's Mane category, mycelium-on-grain products can legally state a high total milligram weight while a substantial portion of that weight is starch from the growing substrate, not mushroom material, which dilutes the actual beta-glucan and hericenone content relative to what the label implies. This product avoids that by sourcing from fruiting bodies specifically and standardizing to a verifiable 25% beta-glucan minimum rather than leading with an inflated total weight figure. The 1,000 mg daily dose (2 capsules) is a reasonable, moderate serving; some of the human research behind Lion's Mane's cognitive effects has used both higher and lower doses, so this sits toward the middle of what's been studied rather than at either extreme.
FREQUENTLY ASKED QUESTIONS
Why does mycelium versus fruiting body matter this much?
Mycelium grown on grain substrate can make up a large percentage of a product's total labeled weight while contributing little of the mushroom's actual active compound content. A product using fruiting bodies specifically avoids that dilution, which is why this distinction gets flagged prominently rather than treated as a minor detail.
Why beta-glucans as the standardization marker?
Beta-glucans are a verifiable polysaccharide class naturally concentrated in fruiting bodies, and a low beta-glucan reading is one of the clearer signals that a product is diluted with mycelium or grain starch. Standardizing to a disclosed beta-glucan percentage is a stronger transparency signal than an unspecified total extract weight.
Has this been independently lab tested?
The manufacturer states third-party testing is available, but a specific certificate of analysis wasn't reviewed as part of this write-up.
Where is this manufactured?
An NSF GMP-certified facility in the United States, per the manufacturer.
