A daily dose of vitamin D can be used in the battle against Type 2 diabetes, experts have revealed.
Researchers are carrying out a major clinical trial to confirm whether taking vitamin D can prevent or delay the condition, the Daily Express reported.
They believe that the "sunshine vitamin" may reduce diabetes risk by 25 per cent.
The study led by Professor Philip Raskin, from UT Southwestern Medical Center in Dallas, Texas, is a four-year trial across America which will track 2,500 people age 30 or older who have pre-diabetes.
They will be given daily doses of vitamin D about five times higher than usually recommended.
