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.
Creatine
Creatine is phosphorylated by mitochondrial creatine kinase (CK-Mt) to form phosphocreatine (PCr), which serves as a rapidly mobilizable high-energy phosphate reserve. When neuronal ATP is consumed during demanding tasks (synaptic vesicle cycling, ion pump activity, action potential propagation), cytosolic brain-type creatine kinase (CK-BB) catalyzes the transfer of the phosphoryl group from PCr to ADP, regenerating ATP within milliseconds — far faster than oxidative phosphorylation or glycolysis can respond. This PCr/CK shuttle also transports high-energy phosphates from mitochondria to distant synaptic sites. Creatine provides direct neuroprotection by stabilizing the mitochondrial permeability transition pore (mPTP), preventing cytochrome c release and downstream apoptotic cascades. It scavenges reactive oxygen species by acting as a direct antioxidant against superoxide and peroxynitrite. Creatine also increases GLUT4 expression in neurons, improving glucose uptake, and upregulates brain-derived neurotrophic factor (BDNF) expression in the hippocampus, supporting synaptic plasticity and memory consolidation.
Risks & Safety
Bacopa Monnieri

Serious
May interact with thyroid medications.
Rare
Increased bowel movements, decreased appetite.
Creatine

Very safe — one of the most studied supplements in existence. No kidney damage in healthy individuals.
Rare
Muscle cramping, dehydration if water intake is insufficient.
Full Profiles
Bacopa Monnieri →
An Ayurvedic herb used for thousands of years as a memory enhancer. Modern research confirms it — Bacopa reliably improves memory formation, recall speed, and information retention. The catch is that benefits require 8-12 weeks of daily use to manifest; it is not an acute cognitive enhancer. The bacosides (active compounds) are also mildly sedating, making evening dosing common.
Creatine →
Best known as a sports supplement, creatine is increasingly recognized as one of the most effective cognitive enhancers available — particularly for vegetarians, the sleep-deprived, and older adults. It serves as a rapid energy buffer for neurons by recycling ATP, the cell's primary energy currency. The brain consumes enormous amounts of ATP, making creatine supplementation directly relevant to cognitive performance.
