Potential Drug Interactions (12)
Based on known supplement-drug interactions from FDA and NIH data. Always consult your healthcare provider.
- severe
vitamin k + Warfarin
Vitamin K directly counteracts warfarin's mechanism of action (inhibiting vitamin K-dependent clotting factors).
Maintain consistent vitamin K intake. Do not start or stop supplements without consulting your doctor.
- moderate
calcium + Tetracycline antibiotics
Calcium binds tetracyclines in the gut, reducing antibiotic absorption by up to 50%.
Separate doses by at least 2 hours.
- moderate
calcium + Fluoroquinolone antibiotics
Calcium chelates fluoroquinolones, significantly reducing their absorption.
Take fluoroquinolones 2 hours before or 6 hours after calcium supplements.
- moderate
calcium + Levothyroxine
Calcium reduces absorption of thyroid hormone replacement.
Separate doses by at least 4 hours.
- moderate
calcium + Bisphosphonates
Calcium impairs absorption of bisphosphonates used for osteoporosis.
Take bisphosphonates at least 30 minutes before calcium.
- moderate
iron + Levothyroxine
Iron reduces absorption of thyroid hormone replacement.
Separate doses by at least 4 hours.
- moderate
iron + Tetracycline antibiotics
Iron chelates tetracyclines, reducing antibiotic effectiveness.
Separate doses by at least 2 hours.
- moderate
magnesium + Fluoroquinolone antibiotics
Magnesium chelates fluoroquinolones, reducing their absorption and effectiveness.
Take fluoroquinolones 2 hours before or 6 hours after magnesium.
- moderate
magnesium + Bisphosphonates
Magnesium reduces absorption of bisphosphonates.
Separate doses by at least 2 hours.
- moderate
vitamin d + Digoxin
Vitamin D increases calcium absorption, which can increase the risk of digoxin toxicity (arrhythmias).
Monitor calcium and digoxin levels.
- moderate
vitamin e + Anticoagulants
High-dose vitamin E (>400 IU) may inhibit platelet aggregation and enhance anticoagulant effects.
Avoid high-dose vitamin E with blood thinners.
- mild
vitamin d + Thiazide diuretics
Both vitamin D and thiazides increase calcium levels, risking hypercalcemia.
Monitor calcium levels periodically.
