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.

Prodrug that is hydrolyzed to choline and cytidine upon oral ingestion. Choline supports acetylcholine synthesis and phosphatidylcholine membrane repair. Cytidine is converted to uridine, which enhances synaptic membrane synthesis via the Kennedy pathway and upregulates dopamine receptor density. This dual mechanism — cholinergic support plus dopaminergic modulation — is unique among choline sources.
