Researchers claim that vitamin D supplements in early childhood could prevent the development of Type 1 diabetes in later life.
The research showed that children given additional vitamin D were around 30 per cent less likely to develop Type 1 diabetes compared with those not given the supplement.
It suggested that the higher and more regular the dose, the lower the likelihood of developing the condition.
Potential to prevent Type 1 diabetes
Dr Victoria King, Research Manager at Diabetes UK, said: "This study suggests that taking vitamin D in childhood has the potential to prevent the development of Type 1 diabetes.
“However, much more research, in particular controlled trials which compare the results when one group of people are given vitamin D supplements and one group is not, are needed before we can confirm a concrete association between vitamin D and Type 1 diabetes."
The results come from the analysis of five separate studies published previously.
