|---|---|---|
| Half-Life | 2-6 hours (bacosides) | 33-36 hours |
| Typical Dosage | Standard: 300-600 mg daily of extract standardized to 50% bacosides (e.g., Bacognize or Synapsa). Take with fat for absorption. Allow 8-12 weeks for full effects. Evening dosing preferred due to mild sedation. | Standard: 100-300 mg daily with a fatty meal. Ubiquinol form is better absorbed than ubiquinone, especially in older adults. For mitochondrial support: 200-400 mg daily. Statin users may need supplementation as statins deplete CoQ10. |

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.
CoQ10
CoQ10 (ubiquinone/ubiquinol) shuttles electrons between Complex I (NADH dehydrogenase) and Complex II (succinate dehydrogenase) and Complex III (cytochrome bc1 complex) of the mitochondrial electron transport chain. This is the fundamental process of oxidative phosphorylation—electrons flow through the chain to Complex IV, driving proton pumping and ATP synthesis via Complex V (ATP synthase). Without adequate CoQ10, the chain bottlenecks at the CoQ pool and energy production drops, particularly in high-metabolic tissues like neurons. As a lipid-soluble antioxidant, CoQ10 (in its reduced ubiquinol form) protects mitochondrial membranes from lipid peroxidation by terminating free radical chain reactions. It also regenerates vitamin E (tocopherol) from its radical form, amplifying antioxidant capacity. Brain CoQ10 levels decline with age.

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.
CoQ10 →
Coenzyme Q10 (ubiquinone/ubiquinol) is an essential component of the mitochondrial electron transport chain and a potent lipid-soluble antioxidant. Brain tissue has among the highest CoQ10 demands in the body due to intense mitochondrial activity. Levels decline significantly with age, and supplementation supports cellular energy production, reduces oxidative stress, and may slow neurodegenerative processes.
