Serum 25-OH Vitamin D level was evaluated by Chemiluminescence method. Vitamin D deficiency (less than 10 ng/ml) was 57.31 percent in young women. Vitamin D insufficiency (10 to 30 ng/ml) was also 30.55 percent. It was also more deficient in winter 63.27 percent, comparing to summer 50.38 percent. The lowest amount of Vitamin D was seen in the group of 15 to 20 years old. The enough amount of Vitamin D should be considered in women before pregnancy by regard to deficiency of 57.31 percent.
