| Category | Nootropics | Minerals |
| Standard Dose | 500-3000 mg/day of fruiting body extract (standardized to >30% polysaccharides) or 1000-3000 mg/day of mycelium extract (erinacine-enriched) | 1000-2000mg magnesium L-threonate daily (providing ~144mg elemental Mg per 2000mg) |

Contains hericenones (fruiting body) and erinacines (mycelium) that stimulate nerve growth factor (NGF) synthesis in glial cells via activation of the JNK pathway. Erinacines cross the blood-brain barrier via passive diffusion and act as potent neurotrophin-stimulating compounds, activating the TrkA receptor and downstream ERK1/2 signaling cascades to promote hippocampal neurogenesis and synaptic plasticity. Also demonstrates anti-inflammatory activity through suppression of NF-kB and upregulation of BDNF expression.

Magnesium L-threonate (Magtein) was specifically developed by MIT researchers to cross the blood-brain barrier efficiently. L-threonate, a metabolite of vitamin C, acts as a carrier to increase brain magnesium concentration by ~15% (compared to negligible CNS penetration from other Mg forms). Elevated brain Mg2+ enhances NMDA receptor signaling fidelity, increases synaptic density in the hippocampus and prefrontal cortex, promotes BDNF expression, and enhances both short-term and long-term memory via potentiation of pre-synaptic release probability at hippocampal CA3-CA1 synapses.
