Metoprolol and other beta-blockers have been shown in laboratory studies to inhibit some CoQ10-dependent enzymes, and long-term beta-blocker therapy is associated with modestly lower CoQ10 levels. There is no absorption clash: CoQ10 does not change metoprolol's blood-pressure or heart-rate effects, and metoprolol does not change how the body uses CoQ10. Whether this depletion meaningfully causes fatigue, or whether CoQ10 supplementation relieves it, rests largely on mechanism rather than interaction-specific trials.
