Pseudoscience runs rampant throughout the claims of many nutrition experts who extol the virtues of vitamin supplements, Reynold Spector writes for the Skeptical Inquirer. “There is no rigorous scientific evidence for the utility of dietary supplements,” according to Spector, and there’s some evidence that pumping large amounts of vitamins E, C, or A into people’s bodies may actually increase mortality.
The multibillion dollar industry that hawks vitamin supplements may be one of the driving forces behind the proliferation of bad science, according to Spector. And he accuses established journals including the New England Journal of Medicine of proliferating the erroneous research.
It is true, Spector admits, that vitamin supplements can be helpful for certain people, including pregnant women and the elderly. He does, however, encourage moderation.
