Vitamin D might save lives
Taking a daily vitamin D supplement might extend your life, at least if youre an older woman. Thats the suggestion of a comprehensive review published this week by the Cochrane Collaboration.
The analysis looked at 50 prior trials, including 94,148 peoplemostly women living in nursing homes, with an average age of 74from high-income countries. Researchers concluded that over a two-year period, one life was saved for every 161 people who took an average daily dose of less than 800 international units of vitamin D3 (cholecalciferol). Other forms, including vitamin D2 (ergocalciferol) and the active forms of vitamin D (alfacalcidol and calcitriol), did not show the same benefit. People who took vitamin D3 with calcium were more likely to develop kidney stones.
