A recent study was done on women with Polycystic Ovarian Syndrome (PCOS) who also have a vitamin D deficiency. The study found that these women fare better when they taken higher doses of the vitamin. The women in the study had improved glucose and lipid metabolism markers when they increased their daily intake from 1,000 UI, to 4,000 UI.
In another study (performed in 2015), another interesting correlation was found between PCOS and vitamin D deficiency. Fifty women with PCOS were followed, and and measured their levels of vitamin D, TSH, Anti TG, free T3, and free T4. The last of these two are thyroid function markers. At the end of the study, they found something interesting among the women who had Hashimoto’s Thyroiditis (If unfamiliar, it’s an autoimmune thyroid condition also known as Hashimoto’s Disease). Tests showed that these women had significantly lower vitamin D levels than the others in the study.
The Importance of this Key Vitamin
Vitamin D is so absolutely vital to many, if not most, of our physiology systems. A deficiency in the vitamin can cause countless health issues, especially in women who have PCOS. When it comes to this condition, we know that a vitamin D deficiency can contribute to the risk of developing insulin resistance and other metabolic issues.
One is considered to have an insufficiency in this vitamin with a serum 25(OH)D level of 21-29 ng/mL (52-72 nmol/L). If a person’s test levels are below this point, there’s a risk of metabolic hormone negative effects. It can also cause issues with calcium absorption, and parathyroid hormones.
This vitamin also has been shown to help regulate the immune system. When it’s lacking, autoimmune disorders and inflammation can be aggravated. It’s important to note that it’s incredibly difficult to get adequate vitamin D in wintertime without supplements. This is especially true if a person lives in a northern climate, such as Canada and the Scandinavian countries.
