New Brazilian research has shown that increasing levels of vitamin D via supplementation appear to be associated with lower glucose levels and therefore a lower risk of developing type 2 diabetes.
Performed by researchers at the University of Sao Paulo School of Public Health, the new study examined 680 women aged 35-74 who gave blood samples for tests for serum 25-hydroxyvitamin D (25 [OH] D) levels ̵
The results now show that a higher vitamin D level can help reduce the risk of diabetes by providing better glycemic control, possibly due to promoting greater insulin sensitivity and by improving the cellular function of the pancreas, the researchers say.
They also note that other recent studies have also shown a relationship between vitamin D and glycemic control.
"Although a causal relationship has not been proven, low levels of vitamin D can play an important role in type 2 diabetes mellitus," says Dr. JoAnn Pinkerton, NAMS CEO. "Vitamin D supplements can help improve blood sugar control, but intervention studies are still needed."
