Cardiologist WARNS: NEVER Take Vitamin D With These 4 Common Medications After 60

Vitamin D, a fat-soluble hormone that regulates calcium absorption, can interact dangerously with four common medications in seniors over 60: thiazide diuretics (which cause calcium retention), digoxin (where elevated calcium amplifies toxicity risk), statins (where high-dose vitamin D may increase muscle damage risk), and warfarin (where vitamin D can disrupt calcium regulation and affect INR levels), potentially causing arterial calcification, kidney strain, arrhythmias, or inconsistent blood thinning.
