| Standard Dose | 300-450 mg/day of standardized extract (24-55% bacosides, typically Bacognize or Synapsa brands) | 500-3000 mg/day of fruiting body extract (standardized to >30% polysaccharides) or 1000-3000 mg/day of mycelium extract (erinacine-enriched) |
| Timing | With a fat-containing meal to improve absorption of fat-soluble bacosides. Morning or evening — some users report mild sedation. Minimum 8-12 weeks for full cognitive effects. | Morning or split morning/afternoon. With or without food. Effects are cumulative — expect 2-4 weeks before noticeable cognitive benefit. |

Active triterpenoid saponins (bacosides A and B) provide multifaceted neuroprotection: inhibition of acetylcholinesterase (AChE) and activation of choline acetyltransferase (ChAT) to enhance cholinergic neurotransmission; upregulation of tryptophan hydroxylase and serotonin transporter expression to modulate serotonergic tone; antioxidant neuroprotection via induction of superoxide dismutase and glutathione peroxidase; and reduction of beta-amyloid aggregation. Additionally enhances GABA signaling through GABA-A receptor subunit upregulation and glutamate decarboxylase activation.

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.
