Can Vitamin D Reverse Prediabetes?

 In Prediabetes & Diabetes Prevention, Prediabetes Reversal, Research

What do vitamin D use and rates of prediabetes have in common?

Both have risen sharply in recent years.

Vitamin D use because of a number of factors.

Such as:

  • The suggested role of vitamin D in preventing various health problems
  • People are getting their vitamin D levels tested more than ever, and
  • A general wide spread deficiency in North Americans

Prediabetes rates have risen as a result of:

  • Increasing rates of obesity
  • Low physical activity rates
  • High consumption of highly refined carbs
  • As well as genetic factors we don’t yet fully understand

Although there is a lot of good evidence in the research showing prediabetes reversal is possible, and I see it in my own practice, we can always use more ways to prevent type 2 diabetes that are safe, effective and cheap.

And there may be a role for vitamin D to play.

There’s been some research that suggests that vitamin D could help reverse prediabetes, but up until this point, the research has not been conclusive.

And that’s where the D2d study comes in.

D2d is a large study being conducted in the United States.

The researchers have set out to answer the question:

Does supplementation of vitamin D delay the progression of prediabetes to type 2 diabetes?

The research participants are grouped into 1 or 2 groups:

  • Those that receive 4000IU of vitamin D daily or,
  • Those that receive a placebo (which is a “nothing pill”.)

The researchers will follow participants for a total of 2-4 years and test them for development of diabetes.

Up until now, research points to low vitamin D levels as a possible cause of increased risk of type 2 diabetes but there hasn’t been any conclusive evidence.

What’s the link?

There seems to be a relationship between both impaired pancreatic b-cell function and insulin resistance and low vitamin D levels.

Some small studies have shown insulin sensitivity increased with vitamin D supplementation.

If D2d confirms the direct link between vitamin D and type 2 diabetes, then vitamin D supplementation will be likely standard practice in conventional medical approaches to prevent type 2 diabetes.

And use of vitamin D supplement could significantly help to reduce the rates of people progressing from prediabetes to type 2 diabetes.

Wouldn’t that be great?

The results of the study are expected in 2018. 

I’ll keep you posted 🙂

D2d is funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health (NIH),
