Erinacines (from Mycelium)
Potent nootropic compounds from Lion's Mane mycelium that stimulate Nerve Growth Factor (NGF) production.
Also known as: Lion's Mane Mycelium Extract • Hericium erinaceus Mycelium
Overview
Erinacines are a group of cyathane diterpenoids found exclusively in the mycelium of the Lion's Mane mushroom (*Hericium erinaceus*). They are distinct from hericenones, which are found in the mushroom's fruiting body. Erinacines, particularly Erinacine A, are highly valued for their ability to cross the blood-brain barrier and stimulate the synthesis of Nerve Growth Factor (NGF), a crucial protein for the growth, maintenance, and survival of neurons. This makes erinacine-rich mycelium extracts a powerful tool for supporting brain health, memory, and nerve regeneration.
Key Benefits
Stimulates Nerve Growth Factor (NGF)
Erinacines are among the most potent natural compounds known to induce the production of NGF, which is vital for neuronal health and plasticity.
Enhances Cognitive Function
By promoting neurogenesis and protecting brain cells, erinacines can improve memory, focus, and overall cognitive performance. They are studied for their potential in age-related cognitive decline.
Supports Nerve Regeneration
The NGF-boosting properties of erinacines can aid in the repair and regeneration of damaged nerves, showing potential for peripheral neuropathy and nerve injuries.
Neuroprotective Effects
Erinacines exhibit antioxidant and anti-inflammatory properties within the brain, helping to protect neurons from oxidative stress and damage associated with neurodegenerative diseases.
Dosage & How to Take
The effective dose depends on the concentration of erinacines in the extract. It is crucial to choose a product standardized for its erinacine content, which is typically derived from mycelium grown in a liquid culture.
| Purpose | Dose | Notes |
|---|---|---|
| Cognitive Enhancement | 500-1000 mg/day | A standard dose for daily nootropic support. |
| Therapeutic and Neuroprotective Support | 1000-3000 mg/day | Higher doses may be used for more significant neurological concerns, under the guidance of a healthcare professional. |
Best Time to Take
Can be taken any time of day. Some users prefer taking it in the morning to support focus throughout the day.
With or Without Food
Not required. Can be taken on an empty stomach or with a meal.
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| Standardized Mycelium Extract (Capsules/Powder) | High | Targeted nootropic and neuroprotective benefits. | This is the only form that provides a guaranteed and effective dose of erinacines. Look for extracts from liquid-fermented mycelium, not mycelium grown on grain. |
| Lion's Mane Fruiting Body Extract | Low (for erinacines) | General immune and gut health benefits. | Contains hericenones, which also have benefits, but is virtually devoid of erinacines. |
Side Effects & Safety
Common
- None reported in clinical studies. It is extremely well-tolerated.
Rare
- Some anecdotal reports of mild itching, which may be related to an increase in NGF.
Contraindications
- There are no known contraindications. However, as with any supplement, consult a healthcare provider if you are pregnant, nursing, or have a medical condition.
Interactions
Erinacines are not known to have any significant drug or supplement interactions.
Scientific Research
Erinacine A-enriched Hericium erinaceus mycelium produces antidepressant-like effects through modulating BDNF/PI3K/Akt/GSK-3β signaling in mice
The study demonstrated that erinacine A-enriched mycelium had significant antidepressant effects in mice, comparable to the drug fluoxetine.
