| Typical Dosage | 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. | Standard: 100-300 mg daily with a fatty meal. Ubiquinol form is better absorbed than ubiquinone, especially in older adults.

Mechanism of Action
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.

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.
