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.

    Vanadium for diabetes?

    Research during the 1980’s showed that this trace mineral could lower blood sugar levels.

    Now, 2 decades later, we’re still waiting for rigorous research in humans, according to reviewers from the University of Southampton, in the UK.

    First, the details.

    • The reviewers included studies where the effects of vanadium were compared to placebo in adults with type 2 diabetes.
    • There had to be at least 20 participants in each study.

    And, the results.

    • 151 studies were found, but none met the inclusion criteria.
    • Based on what was available, 30 mg to 150 mg of vanadium taken daily in people with diabetes seemed to have some effect on blood sugar levels, but the studies were so poorly designed that the results must viewed cautiously.
    • Treatment with vanadium often resulted in gastrointestinal side effects.

    The bottom line?
    The authors concluded that when it comes to diabetes, “The routine use of vanadium… cannot be recommended.”

    A product called Vanadyl is sold to treat diabetes; and in Italy, vanadium is among the 10 most frequently recommended dietary supplements by herbalists for diabetes treatment.

    More about vanadium can be found in this review by John Walsh, a physician’s assistant and certified diabetes educator.
