Vitamin D and Calcium Help Solve PCOS Puzzle

I've reported on this before but here's an update.

Shahid Sedughi University in Iran has recently released a study of 100 infertile women with PCOS who were all taking 1,500 mg. of metformin.

The women were divided into two groups. One group took calcium 1000 mg/day and vitamin D 100,000 IU/month for six months. (IU = international units). The other group did not take any supplements.

So what happened by the end of six months? In the vitamin D and calcium group, body mass index improved, menstrual regularity increased, follicle maturation improved and fertility improved more than in the group who took nothing.

At the beginning of the study, an amazing 83% of the PCOS patients showed vitamin D deficiency, with 35% severely deficient. By the end of the study, 74% of these women had adequate vitamin D levels.

This study affirms earlier evidence that vitamin D adequacy is very helpful for improved fertility and for reducing most symptoms of PCOS. This is why so much vitamin D is included in the d-Pinitol formula.

And here's another benefit of having enough vitamin D and calcium. The Harvard School of Public Health has reported that a decrease in overall risk of ovarian cancer was associated with high intake of total calcium. They also reported that intake of vitamin D was associated with reduced risk of endometrial cancer, but not ovarian cancer.

Regarding pregnancy, higher vitamin D levels were associated with reduced gestational diabetes, fewer C-sections, and reduction of preterm births, according to a study from Hospital Clinico San Carlos-IdISSC in Spain.

The best place to get your vitamins and minerals is from your diet. However, diet is not enough. Our diet today is insufficient in some vitamins and minerals. Secondly, PCOS may increase your needs for certain nutrients, such as vitamin D, calcium, or inositol. So you'll want to take a look at supplementation.
