SUNSCREEN MYTH. “The belief that sunscreen lotion blocks vitamin D production is based on a 1987 study done by Matsuoka et al., that was funded by the ultraviolet foundation, which is supported by the tanning bed industry. Contradictory information was provided by Diehl and Chiu which concluded that although sunscreens are effective, many may not actually be blocking UV-B because they are improperly or inadequately applied.”
