Type 2s Not Getting Enough Vitamin D


By: Daniel Trecroci

Italian researchers say that approximately three out of every five people with type 2 diabetes show signs of vitamin D deficiency.

Blood levels of vitamin D were studied in 459 individuals with type 2 diabetes and 459 nondiabetic controls. Vitamin D deficiency was higher in the diabetics than in the controls.
