Lion’s Mane Extract

What it is & why it matters

Lion’s Mane (Hericium erinaceus) is a medicinal mushroom traditionally used in East Asia for cognitive and nerve support. It contains unique compounds (hericenones and erinacines) that have been shown in early research to stimulate Nerve Growth Factor (NGF), a protein involved in the growth and maintenance of neurons. This makes it one of the most interesting natural compounds currently being studied for brain health.

Evidence rating: ⭐⭐⭐ Promising (Emerging) — Early human research and strong mechanistic data are encouraging, but larger, well-controlled clinical trials are still needed before strong claims can be made.

Simple Dosage (updated 2026 guidance)

• Typical studied dose: 1,000–3,000 mg per day of Lion’s Mane extract (often standardised for hericenones or erinacines).
• Most human studies used 1,000–2,000 mg daily, split into 1–2 doses.
• Consistency over many weeks appears more important than high single doses. Effects, when seen, have sometimes declined after supplementation stopped.

Take with or without food. No loading phase is required.

Why Lion’s Mane is being studied for different people

Lion’s Mane for Brain Health & Cognition

Early research, including a small human trial, suggests Lion’s Mane may support cognitive function in older adults with mild cognitive impairment. Mechanistic studies show it can stimulate NGF, which plays a role in neuron growth and survival. While promising, current evidence is still limited and larger studies are needed.

Lion’s Mane for Healthy Ageing

As we age, maintaining cognitive resilience becomes increasingly important. Lion’s Mane is being researched for its potential to support nerve health and neuroplasticity over time. Current data is still early-stage, but the NGF-stimulating properties make it an interesting compound for long-term brain health strategies.

Lion’s Mane for Mood & Mental Health

One small human study found improvements in mood, anxiety, and sleep quality in overweight adults taking Lion’s Mane. However, this study had limitations (small sample size and no placebo control), so results should be interpreted with caution. It offers an interesting signal but is not yet conclusive.

Expert view: Mycologist Paul Stamets and neuroscientist Dr. Andrew Huberman have both discussed Lion’s Mane, noting its unique NGF-stimulating compounds. They view it as promising but stress that larger human trials are still needed before strong claims can be made.
