Vitamin D and Diabetes Risk
A new study shows a strong association between lower levels of vitamin D in the blood and a higher risk of developing type 1 diabetes (i.e., requiring insulin). The risk of diabetes was more than 3.5 times as great among people with low levels of vitamin D compared to those with higher levels -- although no additional benefit was found for people with the highest levels of vitamin D. Find out more -- including the specific level associated with the lowest risk of type 1 diabetes -- in the updated Vitamin D Supplements Review, which includes our test results for 51 vitamin D supplements.
