Why do i feel nauseated after taking vitamins? i make sure to eat first and don't take them on an empty stomach. feel like throwing up :(

Not unusual: There are several reasons why taking a multivitamin causes nausea. Vitamins C, E and iron all tend to cause more irritation to your stomach. Be sure not to over dose on these (RDA is 75 mg vitamin C, 15 mg vitamin E, 18 mg iron). Fat solubles can accumulate; stick to RDA of vitamins A-700 mcg, D-600 IU, E-15 mg, K-90 mcg. Coatings slow absorption causing irritation. Try a gummie or chewable.
