  • Improved memory
  • Cognitive enhancement

How it works

Stimulates nerve growth factor, supporting neurogenesis and long-term brain health.

Overview

Lion’s Mane is one of the most researched nootropic mushrooms, with evidence suggesting it may support nerve growth factor production. This makes it particularly relevant for long-term brain health, neuroplasticity, and memory formation. Its effects are gradual and build over time, making it a foundational supplement rather than an acute performance enhancer.

The evidence

Preliminary. Preclinical findings are encouraging, but human trials are small and short. Treat current claims as promising rather than proven — exactly the kind of nuance the grade reflects.

Dose

500–1000 mg/day of a characterised extract; potency varies widely between products.

Timing

Chronic — any cognitive benefit is expected to build over weeks to months.

Safety

Generally well tolerated. Extraction method matters for both potency and regulatory status — verify novel-food position for the specific extract.
