                                According to the American Association of Poison Control Centers, vitamin exposures are common, but most do not lead to serious harm. So, what happens if I accidentally take my vitamins twice? The effects depend on whether the vitamins are water-soluble or fat-soluble, with most double doses of multivitamins posing a low risk of serious harm for healthy adults.
