What Vitamins Should I Take, Really?

At some point or another, the idea that vitamins are a necessary part of every day was likely ingrained in you by a parent or a doctor, but recent studies have called the effectiveness of common supplements into question. A 2018 study found that the most common vitamins—multivitamins, vitamin D, calcium, and vitamin C—did not provide any consistent health benefits or harms. Additionally, a Consumer Lab product review from 2017 found 46% of multivitamins don't do what they claim.
