A new study published in The American Journal of Clinical Nutrition claims that an increased intake of vitamin D may decrease the risk of developing certain types of cancer.
In the study, researchers followed 1, 179 post menopausal women in rural Nebraska. The women were divided into three groups, based on the amount of their vitamin D intake. One group took placebo pills, another group took a combination of calcium and vitamin D supplements, and final group took only vitamin D supplements.
After four years of following the study participants, researchers found that the group that took a combination of calcium and vitamin D supplements decreased their risk of developing cancer by 60 percent. The group took between 1,400 and 1,500 mg of calcium and 1100 UI's of vitamin D, about triple the recommended daily amount.Vitamin D Supplements Can Be Very Dangerous
