Blood sugar problems? Might want to make sure you get your daily dose of D.

More research is needed to confirm a connection between blood sugar control and vitamin D levels. But in a study, people with type 2 diabetes had better success in lowering their blood sugar when they followed a diet that included extra vitamin D.

In the study of middle-aged men and women, half the study participants drank vitamin-D-fortified yogurt drinks twice a day with lunch and dinner while the other half drank a placebo drink of just yogurt. After 12 weeks, the people in the vitamin D group not only had lower blood sugar but also showed fewer signs of insulin resistance. The vitamin D group even lost a bit of weight over the 12-week period!

More research is needed to know for sure whether vitamin D may have a role in blood sugar control. And it's not clear whether other foods containing D -- or supplements -- would produce similar blood sugar benefits. But lots of other research suggests that D may help improve insulin sensitivity and may even be involved in helping regulate insulin secretion from the pancreas -- all important parts of blood sugar control. So be sure to get your fair share of vitamin D each day. In the study, the vitamin D drinkers were getting about 1,000 international units (IU) each day -- more than current government recommendations.
Vitamin D may improve your blood sugar levels, according to some research. In one study, people with type 2 diabetes experienced improvements in their blood sugar levels after three months of consuming a yogurt drink fortified with vitamin D twice a day.

Other research has found that low blood levels of vitamin D can raise the risk of insulin resistance, a condition in which the body doesn't respond normally to the hormone insulin, which can lead to diabetes. Studies have also found that taking vitamin D supplements may improve insulin resistance in people who already have the problem. Talk to your doctor for more information about vitamin D and blood sugar control.
