Why vitamin B6 could raise the risk of hypoglycemia for people with diabetes

A large-scale Mendelian randomization study found no genetic evidence that vitamins A, C, or D reduce the risk of major diabetic complications. However, higher genetically predicted vitamin B6 levels were strongly associated with increased risk of diabetic hypoglycemia, warranting caution with supplementation.
