A new trial published in Clinical Nutrition has found that vitamin D and calcium co-supplementation results in improved glucose metabolism and levels of certain lipids in women with polycystic ovary syndrome.
Polycystic ovary syndrome (PCOS) is a common disorder affecting nearly 5% of all women of reproductive age. The condition has been covered here on our blog, especially with the increase in research on vitamin D and PCOS over the past year.
Researchers are still trying to reveal the dynamics of the variables that are involved in PCOS. Chief among these variables is insulin resistance. Insulin resistance is very common in women with PCOS and contributes to many of the classic symptoms, including infertility.
When the body becomes resistant to the hormone insulin, cells can’t respond to its actions, which lead to an abnormal increase in insulin levels and unhealthily high blood sugar levels. In PCOS, this contributes to an increase in testosterone and subsequent increased risk for infertility.
In attempting to understand the full role insulin plays in PCOS, researchers have begun to speculate how vitamin D might fit into this relationship.
