Can Calcium Help PCOS?

Can Calcium Help PCOS?
A number of studies have found that women with PCOS are more likely to be deficient in vitamin D than women without PCOS, and that vitamin D supplementation my be helpful. But women often wonder, should they take calcium too?

Taking calcium and vitamin D together may have some beneficial effects upon PCOS according to a number of studies. A 2016 study (1) tested a combination of vitamin (200IU), vitamin K (90 mcg) and calcium (500 mg) taken twice daily - or a placebo - in sixty women with PCOS who were vitamin D deficient.

After eight weeks of treatment supplementation was linked with a significant drop in levels of free testosterone and dehydroepiandrosterone sulfate (DHEAS), and significant increases in antioxidant levels (TAC). Levels of a key marker of oxidative stress, malondialdehyde (MDA), also dropped.


“Overall, vitamin D-K-calcium co-supplementation for 8 weeks among vitamin D-deficient women with PCOS had beneficial effects on serum DHEAS, free testosterone, plasma TAC, and MDA levels.”


An earlier study looked at how supplementation with calcium and vitamin D might influence other aspects of PCOS: glucose metabolism and lipid concentrations.

Women with PCOS who were diagnosed as being overweight or obese and who were vitamin D deficient were randomly assigned to receive either: calcium 1000 mg/day, vitamin D, 50,000 IU/week, calcium, 1000 mg/day plus vitamin D 50,000 IU/wk or a placebo.

Supplementing calcium and vitamin D together resulted in higher levels of vitamin D and decreased levels of serum insulin, homeostasis model of assessment-insulin resistance (HOMA-IR) scores, and significantly improved quantitative insulin sensitivity check index (QUICKI) scores.

Co-supplementing calcium with vitamin D was also linked with significant decreases in serum triglycerides, and VLDL- cholesterol levels - that's the bad kind of cholesterol.


“In conclusion, calcium plus vitamin D supplementation for eight weeks among vitamin D deficient women with PCOS had beneficial effects on serum insulin levels, HOMA-IR, QUICKI, serum triglycerides and VLDL-cholesterol levels, but it did not affect FPG and other lipid profiles.”


Another study on the same treatment protocol found that a key marker of inflammation - C-reactive protein (HsCRP) - was also reduced with this treatment strategy along with levels of an important marker for oxidative stress - malondialdehyde (MDA).

Researchers also noted significant increases in the total antioxidant capacity (TAC) along with increases in levels of a key antioxidant glutathione.


“We found that calcium plus vitamin D co-supplementation for 8 weeks among overweight and vitamin D-deficient women with PCOS had beneficial effects on inflammatory factor and biomarkers of oxidative stress.”


If you have PCOS and your body tends toward being overweight or obese, there may be some merit to adding some calcium and vitamin K to your vitamin D supplements.
