Can Vitamin D Reverse Prediabetes?
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.
- 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?
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 🙂
