The study, conducted by Manish Paranjpe, a student at Harvard Medical School in Boston, and a team of researchers, used CDC data gathered from 20,000 people. According to their findings those that people who pop the daily pill claim to have “excellent” or “very good” health — 30% more often than people who don’t take them. Then, they looked at the data and found that the supplements didn’t really impact their health. In fact, there were no differences in whether they required help with routine activities, had a health history that included any of 10 chronic diseases and 19 acute conditions, or experienced psychological distress in the past month.
“MVM users self-reported better overall health despite no apparent differences in clinically measurable health outcomes,” the study concluded. “These results suggest that widespread use of multivitamins in adults may be a result of individuals’ positive expectation that multivitamin use leads to better health outcomes or a self-selection bias in which MVM users intrinsically harbour more positive views regarding their health.”
“The effect of positive expectations in [those who take multivitamin/mineral supplements] is made even stronger when one considers that the majority of [them] are sold to the so-called ‘worried-well’,” they added in a press release. “The multibillion-dollar nature of the nutritional supplement industry means that understanding the determinants of widespread use has significant medical and financial consequences.”
