Melatonin and mealtime: Common genetic difference could put some at greater risk of diabetes

New light has been shed on why people who carry a common genetic mutation may be more at risk for developing type 2 diabetes. By carefully studying healthy subjects, researchers were able to chart the effect of melatonin supplements on blood sugar control. Their results suggest that taking melatonin close to mealtimes may put people with a common genetic variant more at risk.
