Glucose level out of control? Maybe a vitamin D supplement helps
If you're in the process of developing type 2 diabetes, it's worth taking a look at your vitamin D too. If your vitamin D levels are low, vitamin D supplementation - or exposure to more sunlight - may make a difference.
Study
The researchers gave half of the subjects a placebo during the 6 months of the experiment. The other half received a vitamin D supplement.
All subjects received lifestyle advice.
Just before, during and at the end of the supplementation period, the researchers determined the HOMA-IR of the subjects. This means that, based on the insulin level and the glucose level before breakfast, they calculated how hard the body had to work to control the glucose level.
The higher the HOMA-IR, the worse things are.
Results
The HOMA-IR was reduced by the vitamin D supplement. That is positive and the figure suggests a dramatic positive effect. However, you must realize that a HOMA-IR of 3 or higher indicates full blown diabetes - and that a HOMA-IR of 1 or less is healthy.
Supplementation moved the mean HOMA-IR from the diabetic zone to the top of the pre-diabetic area. This effect is positive, but you should not overestimate it.
Conclusion
