Lion's ManevsMagnesium L-Threonate

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.

The L-threonate carrier forms stable complexes with magnesium and transports it across the blood-brain barrier via specific transporters more effectively than inorganic magnesium salts or other chelated forms. Once in the brain, magnesium acts as a voltage-dependent blocker of the NMDA receptor channel at the physiological magnesium binding site within the ion pore, preventing excessive calcium influx and glutamate-mediated excitotoxicity. Magnesium also serves as a cofactor for over 300 enzymes including those involved in neurotransmitter synthesis (tyrosine hydroxylase, glutamic acid decarboxylase), ATP production (creatine kinase, pyruvate kinase), and DNA/RNA polymerase. Elevated brain magnesium enhances synaptic density and plasticity in the hippocampus and prefrontal cortex, likely through CREB-mediated gene expression and increased density of postsynaptic AMPA receptors.
