What it is
A lipid-soluble benzoquinone present in mitochondrial membranes. Available as oral softgels and capsules in oxidized (ubiquinone) and reduced (ubiquinol) forms.
How it works
Functions as an electron carrier between mitochondrial complexes I/II and III in the electron transport chain and acts as a lipid-soluble antioxidant in cell membranes.
Where it's used
Used as a dietary supplement marketed for cardiovascular and mitochondrial support, particularly in statin users.
FDA-approved use
Regulated as a dietary supplement.
Tracking it
CoQ10 is oral, which makes consistency the whole game — a simple daily check-off with a reminder beats memory every time. with a half-life of about 34 hours, a dose log also lets a tracker model the relative amount still in your system between doses.
