 Many of us spend gazillions of dollars every year on multivitamins, but this is a real and big study. This is not one of those, I don't know, online survey by some company that benefits somehow from you not taking vitamins. This is research from the National Cancer Institute, one of the largest and longest investigations into multivitamin use and mortality to date, published in JAMA. That's one of your biggest publications for all health stuff.
