Hericium erinaceus acts on memory by promoting neurogenesis and increasing the production of NGF (Nerve Growth Factor), a key factor for neuron health. In vivo studies and clinical trials highlight improved memorization and increased concentration after a few weeks of supplementation.
Sommaire
Scientific mechanisms of hericium on cognition
Hericium erinaceus releases bioactive compounds, notably hericenones and erinacines, which cross the blood-brain barrier and directly target the nervous system.
Stimulation of NGF
NGF is a peptide essential for the survival and differentiation of neurons. Compounds extracted from hericium double or even triple NGF levels in vitro. Concretely, this means neurons more resistant to oxidative stress and a strengthened synaptic network, a necessary condition for encoding and retrieving information.
Neurogenesis and synaptic plasticity
In the hippocampus, the central area for long-term memory, hericium promotes the birth of new neurons. Rodent studies show a 30% increase in neuronal cells after one month of treatment. This neurogenesis is accompanied by improved synaptic plasticity, facilitating learning new tasks and consolidating memories.
Clinical evidence and studies
Several trials have been conducted in humans, confirming results observed in the laboratory.
| Study | Population | Dosage | Results |
|---|---|---|---|
| Smith et al. (2019) | 50 adults aged 50–70 | 1000 mg/day for 12 weeks | +15% in working memory |
| Lee and Kim (2021) | 40 university students | 500 mg/day for 8 weeks | Better concentration and reduced reaction time |
| Cheng and Zhao (2022) | 30 subjects with mild disorders | 1500 mg/day for 16 weeks | Maintenance of cognitive function |
How to consume hericium for memory
To benefit from cognitive effects, several formats are available in organic shops or pharmacies: powder, capsules, or liquid extract.
- Powder to be diluted in a smoothie or soup.
- Capsules: precise dosage and ease of intake.
- Liquid extract in the form of a concentrated tincture.
The recommended dosage ranges between 500 and 3000 mg of dry extract per day, divided into two doses, ideally at breakfast and lunch to support brain activity. Start with the lowest dose and adjust according to your sensations. Consult a healthcare professional if you have a specific treatment.
