The C.A.M. Report
Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    More research on vitamin D and diabetes

    It has been observed that low levels of vitamin D and calcium are associated with higher risk of type 2 diabetes.

    Now, researchers in Boston report an explanation underlying the relationship.

    First, the details.

    • 92 adults at high risk of diabetes were randomly assigned to a treatment group for 16 weeks.
      • Cholecalciferol (a form of vitamin D, also called vitamin D3) 2000 IU once daily
      • Calcium carbonate 400 mg twice daily
      • Placebo
    • Pancreatic beta cell ability to secrete insulin was measured using a glucose-tolerance test.
    • Insulin response, insulin sensitivity, and measures of changes in blood levels of glucose were also measured.
    • Neither the patients nor researchers knew the treatment given — double blind.

    The bottom line?

    • Participants had an A1c of 5.9%.
      • A1c test is used as a standard tool to determine blood sugar control for patients with diabetes.
      • Levels at or higher than 6.5% are diagnostic for diabetes.
    • Higher levels of vitamin D were associated with significantly improved insulin secretion.
    • A1c was not changed in either group.
    • There was no significant difference in any outcomes with calcium compared with no calcium.

    The bottom line?

    The value of this study is that it shows a logical progression from observation to analytical testing of a hypothesis. It has limited application to treatment at this time.

    Accordingly, the authors concluded, “In adults at risk of type 2 diabetes, short-term supplementation with cholecalciferol improved beta cell function.”
