A month after Boston ­researchers reported that multi­vitamins could cut cancer risk, new results released Monday from the same study bring disappointing news: Multi­vitamins do not offer any benefits for preventing heart disease.

The study, conducted by Brigham and Women’s Hospital, involved nearly 15,000 male physicians over age 50 who were randomly assigned to take a Centrum Silver multivitamin or a placebo for an average of 11 years. The researchers found that multivitamins offered no protection against heart ­attacks, strokes, or deaths from heart disease.
