New Vitamin D Study Ignores Vast Scientific Evidence – Discourages Important Future Research

WASHINGTON, D.C.– A new study and an accompanying editorial published in the Journal for the American Medical Association contradicts scientific research related to Vitamin D’s importance in numerous disease states including but not limited to managing diabetes.  Furthermore, these claims are at odds with the current state of the science:

  • According to the American Diabetes association, there is growing evidence that vitamin D deficiency could be a contributing factor in the development of both type 1 and type 2 diabetes, and that in Type 2 diabetic patients, severe vitamin D deficiency predicts increased risk cardiovascular mortality.
  • A study conducted on a National Institute of Health population found that “people who were low in vitamin D—below 30 ng/ml—were at five times the risk of developing diabetes as people who were at a healthier vitamin D level—50 ng/ml—over a period of 12 years.”
  • A study in the European Journal of Endocrinology examining the effects over 6-months of vitamin D supplementation on insulin sensitivity and secretion found that Vitamin D supplementation may slow the progression of type 2 diabetes in newly diagnosed patients and those with prediabetes.

“We were shocked when this study came out because of its total disregard for the wealth of scientific research and medical guidance in the U.S. and around the world. Vitamin D deficiency puts people at a heightened risk for a number of severe health challenges including the risk of developing diabetes, so a daily supplement at the advice of a doctor is an excellent way for people to get the right amount,” said Daniel Fabricant, Ph.D., president and CEO of NPA.

Vitamin D’s benefits extend past aiding and managing diabetes.

  • According to researchers at the University of Ulster in the United Kingdom, supplementation with vitamin D in the most at-risk of impaired bone health has a beneficial effect on fracture preventions.
  • A study conducted by Ohio University found that the presence of vitamin D in the cardiovascular system significantly reduced levels of oxidative stress, improving cardiovascular health in general.
