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.

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.
