|---|---|---|
| Half-Life | 2-2.6 hours | Bioactive compounds (hericenones, erinacines) accumulate with daily use; effects are cumulative |
| Typical Dosage | Standard: 125-375 mg daily in 2-3 divided doses. Commonly 125 mg twice daily. Take with food. Effects are noticeable within 30-60 minutes. Russian clinical practice uses 4-6 week courses. | Standard: 500-3000 mg daily of fruiting body extract. For NGF stimulation: look for extracts containing both hericenones (from fruiting body) and erinacines (from mycelium). Dual-extract products provide both. Take consistently for 4+ weeks for noticeable effects. |
| Administration | Oral (tablets). Also available as IV/IM injection in clinical settings. Mexidol is the brand name. | Oral (capsules, powder, tincture, whole mushroom). Extracts standardized for beta-glucans and/or hericenones are preferred. |

Mechanism of Action
Emoxypine (Mexidol)
Emoxypine (2-ethyl-6-methyl-3-hydroxypyridine succinate) has a 3-hydroxypyridine structure similar to vitamin B6 (pyridoxine). It is one of the most potent inhibitors of lipid peroxidation in brain tissue — it scavenges hydroxyl radicals and peroxyl radicals, inhibits Fe2+-induced lipid peroxidation, and may chelate transition metals. It modulates the GABA-benzodiazepine receptor complex (GABA-A), enhancing GABAergic transmission through positive allosteric modulation — possibly at a site distinct from the classical benzodiazepine binding site, explaining the lack of sedation and tolerance. It improves mitochondrial function (Complex I protection, membrane stabilization), stabilizes cell membranes (reducing fluidity changes during oxidative stress), and enhances cerebral microcirculation (possibly via nitric oxide or prostaglandin modulation). The anxiolytic mechanism may involve partial agonism or different subunit selectivity.
Lion's Mane
Lion's Mane contains two classes of bioactive compounds: hericenones (A-H, found in the fruiting body) and erinacines (A-I, found in the mycelium). Both stimulate the synthesis of nerve growth factor (NGF) in astrocytes and neurons — hericenones may act through enhancement of NGF gene expression, while erinacines cross the blood-brain barrier and directly induce NGF. NGF binds to TrkA receptors and is essential for the survival, maintenance, and regeneration of cholinergic neurons, particularly in the hippocampus and basal forebrain. This promotes neurogenesis, dendritic arborization, and remyelination of nerve fibers. Lion's Mane also reduces neuroinflammation through inhibition of NF-κB signaling and suppression of pro-inflammatory cytokine production. It may enhance BDNF expression and support the gut-brain axis.

Full Profiles
Emoxypine (Mexidol) →
A vitamin B6 derivative with powerful antioxidant and anxiolytic properties, widely prescribed in Russia and Eastern Europe for anxiety, cognitive impairment, and cerebrovascular disease. Emoxypine inhibits lipid peroxidation, modulates GABA-A and benzodiazepine binding sites, and improves cerebral blood flow. It provides anxiolytic effects similar to benzodiazepines without sedation, tolerance, or addiction.
Lion's Mane →
An edible mushroom (Hericium erinaceus) that is the only known natural compound proven to stimulate nerve growth factor (NGF) synthesis in the brain. This makes Lion's Mane uniquely valuable for neurogenesis, nerve repair, and long-term brain health. Effects build over weeks of consistent use rather than being felt acutely. Studied for cognitive decline, neuropathy, and depression.
