“The study proposed that low-cost vitamin D supplementation could make the development of diabetes in over 10 million people longer than expected.”

A review of clinical trials has found that consuming higher vitamin D may lead to a lower risk of developing type 2 diabetes in adults with prediabetes. Vitamin D is a fat-soluble vitamin added to or available in some foods, as a supplement, or produced by the body when the skin gets struck by ultraviolet rays from sunlight.

Vitamin D performs multiple functions in the body, comprising a role in glucose metabolism and insulin secretion. Observational studies have identified a link between a high risk of developing diabetes, and a low level of Vitamin D in the blood.

A systematic health review was conducted by the Tufts Medical Center, US and a meta-analysis of three clinical trials comparing vitamin D supplement impacts on diabetes risk.

The researchers from the US got that for more than a three-year follow-up period, 22.7 per cent of adults who received vitamin D were seen with new-onset diabetes, and 25% of adults who got the placebo, a 15% relative reduction in risk was found.

The journal Annals of Internal Medicine’s study derived the findings of over 374 million adults globally with prediabetes. The health study proposed that low-cost vitamin D supplementation could make the development of diabetes in over 10 million people longer than expected.

In a following editorial, researchers from University College Dublin and the Food Safety Authority of Ireland heed that earlier research has shown significant adverse effects of high vitamin D intake.

They argue that professional societies promoting vitamin D therapy must warn physicians about both required vitamin D intake and safe limits.

The researchers also suggest that an extremely high dose of Vitamin D might stop type 2 diabetes in some patients but may also cause harm.
