Meta-analysis: Vitamin D levels and risk of heart disease, early death

Posted on: September 18, 2012   by  John Cannell, MD

    “Then they did a metanalysis of 18 general population studies that included more than 82,000 people. The studies used various definitions of inadequacy. They found the risk of early death with “inadequate levels” was 46%.”

  2. John Cannell, MD

    The people with the low levels had a 46% greater chance of death from heart disease.
