Vitamin D May Reduce Risk for Type 2

Vitamin D Supplements Can Reduce The Risk of Developing Type 2 Diabetes, Vitamin D

| Aug 3, 2011

A Boston-based study has found that vitamin D supplements can reduce the risk of developing type 2 diabetes in people with prediabetes by improving their beta cell functioning.

Researchers at Tufts University Medical Center tracked the effects of vitamin D3 supplements on 92 subjects who were considered to have prediabetes by virtue of being overweight and having higher-than-normal blood sugar levels. (In prediabetes, blood sugar levels are high, but do not yet reach the levels found in full-blown diabetes.)

The subjects were divided into four study groups, with one group receiving the vitamin D supplements, a second group receiving vitamin D and calcium, a third group receiving calcium only, and a fourth group receiving a placebo.

Researchers tracked participants' blood sugar levels using the A1C test and monitored their pancreatic beta cell function, including how much insulin the cells were producing and the patients' sensitivity to the hormone.  

The four-month study showed that the vitamin D groups enjoyed slightly lower A1C levels and a 15 percent to 30 percent improvement in beta cell function. The other groups showed no similar gains.

The study scientists were careful to point out that the results do not show that vitamin D can prevent the onset of type 2, only that it may be one element in a series of steps that people with prediabetes can take to avoid developing the disease. Maintaining insulin sensitivity and control of blood sugar levels are mainstays in diabetes prevention.

An abstract of the study is available online at the American Journal of Clinical Nutrition.

As often is the case, reports of studies often are interpreted in ways that are not supported by results. The patients, who already were displaying blood sugar abnormalities (HbA1c of 5.9% on average) had improved insulin responses with Vit D3 supplementation. But what is going on? Does diabetes cause vit D deficiency which results in decreased insulin? Or does vitamin D deficiency cause diabetes which results in decreased insulin? Who knows? This study cannot answer that. The study in fact found that Vit D supplementation did not lead to any statistically significant change in the diabetes progression (HbA1c). So while Vit D can perhaps improve blood sugar control in this population, it is not clear whether it plays any role in diabetes progression.

Im taking 400 iu of vitamin D3 daily plus an additional 325 iu of vitamin D3. What is the recommended dosis, because too much vitamin D can cause damage to your bones and other illness. At the moment, my vitamin D3 levels in my body is on 36 which is normal, according to my blood test results. Comments are more than welcome.
