Vitamin D supplement protects diabetic DNA from free radicals
Vitamin D supplementation has a subtle but positive effect on insulin sensitivity, we reported a few times before. However, the positive health effect of extra vitamin D for people with type 2 diabetes is more significant than you might suspect. In diabetics, vitamin D supplementation reduces damage to DNA by aggressive molecules.
Study
The Poles divided their subjects into 2 groups. Each group contained both diabetics and non-diabetics. One group received a supplement containing 2000 IU of vitamin D3 every day for 3 months, the other did not. The control group did not receive a placebo.
Just before and just after the supplementation period, the researchers studied the blood of the test subjects.
Results
In test subjects with diabetes, vitamin D supplementation also reduced the activity of yet another repair enzyme, endonuclease III [Nth].
The Poles determined the activity of these enzymes in blood cells. They also tested the DNA-damaging effect of the blood as a whole with the comet assay. Vitamin D supplementation also reduced those scores in diabetics.

Conclusion
"Moreover, our results suggest that patients with type-2 diabetes may benefit more from supplementation with vitamin D than the general population."
