Vitamin D plays a well-known role in bone formation. The vitamin, which is actually a hormone, can also play a role in women's fertility and metabolic processes. Researchers at Graz University have recognized a positive effect on blood glucose levels in a study funded by the Austrian Scientific Fund (FWF).
Sun rays increase vitamin D production
Polycystic ovaries are one of the main causes of undesirable infertility in young women. In Austria, about ten to twelve percent of women are affected by this hormonal disorder explained by Graz internist Elisabeth Lerchbaum. Characteristic of the polycystic ovary syndrome (PCOS) are enlarged ovaries and an increase in male sex hormones. In addition to the often unfulfilled desire to have children of the patients, increased risks for patients for cardiovascular disease and type II diabetes are considered as documented by the physician told APA. A common side effect is a vitamin D deficiency, according to the endocrinologist, who for many years has been working on the fat-soluble vitamin and the effects of its substitution.
"At the University Department of Internal Medicine today, we routinely measure vitamin D content among those affected, which is the result of our study's findings on the effects of D supplementation," said the department's physician for endocrinology and diabetology by fellow Graz. In their randomized and placebo-controlled study, 330 women with vitamin D deficiency participated: 180 women with and 150 women without PCOS. They all received a vitamin D supplement once a week for six months.
With improved blood sugar levels
The results were gratifying for the Graz research group: In the women with PCOS, the vitamin had a positive effect on blood sugar levels shortly. In addition to the fixed blood glucose values, the values after a meal were also measured in the study. Thus, very early precursors of type II diabetes can be recorded, Lerchbaum explained. This is relevant inasmuch as slightly elevated blood sugar or elevated insulin levels often occur in the early stages of a PCOS. The researchers' vision is to reduce the risk of diabetes through early intervention.
In any case, at Graz University Hospital for Internal Medicine, vitamin D-deficient PCOS patients receive a medically guaranteed dose of vitamin D and D monitoring in addition to the standard therapy. By observing for a long time, the Graz-based research group would like to find out if the measure can actually delay or even prevent the onset of type 2 diabetes.
As for the dosage, the doctor warns her to take it without medical supervision. She does not recommend taking vitamin D in general without prior determination of the level. Often, an overdose is the result. According to their contribution from the Science Fund FWF PCOS study, "plus" had vitamin D in the healthy participants who were slightly unfavorable to blood glucose.
Vitamin D, unlike other vitamins, can be produced by the body itself. For this reason, vitamin D is not a vitamin in the right sense, but a hormone. Only a small part of the vitamin requirement is covered by the food, but sun rays on the skin really increase production.
