Frequently Asked Questions

How long does lion's mane take to work?

Most clinical studies show measurable cognitive benefits after 4-8 weeks of daily use. NGF stimulation is a gradual biological process — neurons need time to grow and form new connections. Some users report subjective improvements in focus within 2 weeks, but full neuroprotective benefits require consistent long-term supplementation.

Is lion's mane a psychedelic?

No. Despite being a mushroom, lion's mane is not psychoactive and does not produce any hallucinogenic effects. It does not contain psilocybin or any psychedelic compounds. Its mechanism of action involves stimulating nerve growth factor (NGF) production, which supports normal neuronal function rather than altering consciousness.

Fruiting body vs mycelium — which is better?

Fruiting body extracts contain significantly higher concentrations of hericenones and erinacines, the active compounds that stimulate NGF. Mycelium-on-grain products often contain substantial grain starch filler (up to 60-70% by weight), diluting the active compounds. All major clinical trials used fruiting body extracts. Choose products standardized to >30% beta-glucans from fruiting body.
