Can Vitamin Supplements cause headaches?Updated a year ago

If you’re consuming a safe amount of vitamins and minerals, then you shouldn’t experience any side effects. Excessive ingestion of fat-soluble vitamins like A & D or water-soluble vitamins like B & C can cause side effects when taken in large doses. Niacin can also cause headaches (National Headache Foundation).
