A study of 446 European subjects diagnosed with metabolic syndrome found no relationship between blood concentrations of vitamin D and insulin secretion or sensitivity. In this group 20% had vitamin D levels over 30 ng/ml (75 nmol/L). This may suggest that the low vitamin D levels seen in people with diabetes are a result, not a cause of their blood sugar disorder.
