Coenzyme Q10 (Ubiquinone/Ubiquinol)

Lipid-soluble electron carrier in the mitochondrial electron transport chain, shuttling electrons between Complex I/II and Complex III. Essential for oxidative phosphorylation and ATP synthesis. Also functions as a potent lipid-phase antioxidant, protecting mitochondrial membranes from peroxidation. Ubiquinol (reduced form) has superior bioavailability compared to ubiquinone.

Notes

CoQ10 is one of two supplements that belongs in every protocol stack regardless of goals. The other is vitamin D. The electron transport chain cannot function without it. Endogenous production declines with age. Statin drugs actively deplete it by inhibiting the mevalonate pathway, which is shared between cholesterol and CoQ10 synthesis. Anyone on a statin who is not supplementing CoQ10 is accepting unnecessary mitochondrial compromise. Take it with fat. The bioavailability is abysmal without it.
