1,496: That’s the number of published studies about the effectiveness of vitamin supplements between 2012 and 2017. Sorting through all that data, researchers in Toronto concluded that there’s no evidence that the most commonly-used supplements provide consistent health benefits.

“We were surprised to find so few positive effects of the most common supplements that people consume,” Dr. David Jenkins, the study’s lead author, told Science Daily. “Our review found that if you want to use multivitamins, vitamin D, calcium, or vitamin C, it does no harm — but there is no apparent advantage either.”
