It seems like science keeps flip-flopping as to whether multivitamins are worthwhile or useless, with some science claiming the use of multivitamins may cause more harm than good. Overall, you should aim to get the bulk of your vitamins through whole food sources rather than pills. Too bad most of us fail to do so, as the Standard American Diet (SAD) has involved more processed foods over the years — which isn’t good for your health or your gut. While you’re told to make sure you’re getting enough vitamins and minerals, but if you’re not sure of what some of them do, it’s hard to know why you really need them. This should help clear up why you need vitamins B and D. To know how much you need, check the government’s recommended daily intake here.
