At 600mg per capsule, this **Lion's Mane** falls short of the doses used in clinical research on cognitive function. The best-known trial (Mori 2009) used 3,000mg daily — you're getting 20% of that in one serving. Even the minimum studied range starts at 1,000mg, so you'd need at least two capsules daily to approach the low end of what's been tested.

The formula uses a whole-organism blend — mycelium, primordia, and fruiting bodies combined. Fruiting bodies contain hericenones (linked to nerve growth factor stimulation), while mycelium contains erinacines, so you're getting both compound types. That said, without standardization to active compounds, it's hard to know the actual potency.

The clinical evidence for lion's mane is still early-stage — only a handful of small trials exist, and in the best one, cognitive improvements disappeared after participants stopped taking it. If you're trying this for brain support, commit to consistent daily use and consider doubling or tripling the serving to get closer to studied doses.
