CCBs inhibit calcium entry into cardiac and vascular smooth muscle cells. They share structural similarities with compounds that interfere with CoQ10 synthesis. Verapamil in particular has been shown to reduce CoQ10 levels in cardiac tissue — relevant given the heart's extremely high CoQ10 demand.
Kishi et al. (1975) — verapamil reduces myocardial CoQ10; Judy et al. (1983) — CCBs associated with CoQ10 depletion in cardiac patients
Fatigue, reduced exercise tolerance, worsening heart failure symptoms, peripheral edema unrelated to drug mechanism
Ubiquinol CoQ10 100–300mg daily. Particularly important in patients with heart failure or reduced ejection fraction.

CCBs and magnesium both affect calcium handling in vascular smooth muscle — they are physiologically complementary. However, patients on CCBs often have underlying magnesium deficiency that impairs cardiovascular function and blood pressure control.
Houston (2011) — magnesium deficiency is a common finding in hypertensive patients and compounds cardiovascular risk
Muscle cramps, sleep disruption, palpitations, constipation (especially with verapamil)
Magnesium glycinate 200–400mg/day in the evening. Note: magnesium and CCBs are generally safe together and may be synergistic for blood pressure control.
