Mechanism of Action

Bacopa Monnieri

Bacopa's bacosides (bacosides A and B, bacopaside I-VII) enhance synaptic communication by increasing dendritic branching, spine density, and synaptic activity in the hippocampus via modulation of neural cell adhesion molecules (NCAM) and FGF-2. They modulate serotonin through 5-HT3 receptor antagonism (reducing anxiety) and 5-HT2A modulation, dopamine through D1/D2 receptor modulation, and acetylcholine through enhancement of choline acetyltransferase. Bacosides upregulate tryptophan hydroxylase (TPH) and serotonin transporter (SERT) expression, increasing serotonin synthesis and reuptake. The antioxidant properties of bacosides reduce lipid peroxidation and protein carbonylation in the hippocampus via free radical scavenging, protecting neurons from oxidative damage during memory formation. They may enhance CREB phosphorylation and BDNF expression.

Bromantane

Bromantane upregulates tyrosine hydroxylase (TH)—the rate-limiting enzyme in catecholamine synthesis—and aromatic L-amino acid decarboxylase (AADC), the enzymes responsible for converting L-tyrosine to L-DOPA and then to dopamine. This increases neuronal dopamine production capacity rather than depleting vesicular stores like traditional stimulants. The mechanism may involve modulation of transcription factors or enzyme phosphorylation. Bromantane also has anxiolytic properties through enhancement of GABAergic transmission, possibly via GABA-A receptor modulation or increased GABA synthesis. The combination of upregulated dopamine synthesis in mesolimbic and nigrostriatal pathways with GABAergic dampening of anxiety circuits produces sustained motivation, focus, and reduced mental fatigue without the jitteriness or crash typical of dopamine-releasing agents.
