A study suggests that taking a high dose of vitamin D one time per month could cut the risk of suffering a heart attack in the long term.

Researchers in Australia randomly assigned more than 20,000 adults between the ages of 60 to 84 to take a large, 60,000-IU dose of vitamin D3 or a placebo one time per month for five years, according to a study published in the BMJ.
