Vitamin D deficiency 'linked to type 1 diabetes'

16 November 2012

A deficiency in Vitamin D has been linked to Type 1 diabetes in new research from the University of California.

The study, which was published in the December issue of Diabetologia, suggested that vitamin D3 could play a role in preventing the condition.

Researchers analysed millions of blood serum specimens from healthy people who later developed type 1 diabetes, as well as 1,000 healthy controls who did not get the condition.

Professor Cedric Garland said: "Previous studies proposed the existence of an association between vitamin D deficiency and risk of Type 1 diabetes, but this is the first time that the theory has been tested in a way that provides the dose-response relationship."

Based mainly on the results of the study, it was estimated that the level of 25(OH)D needed to prevent half the cases of type 1 diabetes is 50ng/ml.

"While there are a few conditions that influence vitamin D metabolism, for most people, 4000 IU per day of vitamin D3 will be needed to achieve the effective levels," Garland suggested.
