                                According to the National Institutes of Health, while most vitamins and minerals do not interfere with hormonal contraceptives, a number of supplements and medications are known to reduce their effectiveness. This means that the belief that common vitamins make birth control ineffective is largely a myth, but it's crucial to understand which substances do present a risk to your contraceptive protection.
