Lion's Mane Extract
Lion's Mane Extract is recommended.
Gold standard for single-ingredient Lion's Mane. ISO in-house lab publishes CoA per batch. Best for buyers who want one ingredient done right.
What it does
Nootropics Depot Lion's Mane Extract is a single-ingredient supplement providing standardised Hericium erinaceus fruiting body extract at 500mg per capsule. Nootropics Depot is widely regarded as the most rigorous ingredient-quality focused retailer in the US nootropics market, operating an ISO-certified in-house testing laboratory and publishing a Certificate of Analysis (CoA) for each batch.
How it works
Lion's Mane fruiting body contains hericenones, compounds that cross the blood-brain barrier and stimulate Nerve Growth Factor (NGF) synthesis. NGF promotes neuronal survival, axon growth, and maintenance of neurons in the hippocampus and cortex -- the regions responsible for learning and memory. Nootropics Depot uses a standardised fruiting body extract rather than mycelium (which has a lower hericenone content). The result is a more potent and consistent NGF stimulus per capsule.
What to expect
Lion's Mane is a long-game supplement. Expect no acute effects on day one. At 4 weeks: some users report slightly clearer thinking and improved mental endurance. At 8-12 weeks: measurable improvements in memory and neuroprotective markers in studies. For best results, take consistently every day with a fat-containing meal (hericenones are fat-soluble). This product is best combined with a multi-ingredient stack (e.g. Mind Lab Pro already contains Lion's Mane) rather than used as a standalone primary supplement.
