Early on in my quest to manage my case of PCOS holistically, I suspected that I had a progesterone deficiency. In Googling possible remedies, magnesium supplementation kept appearing, and so I added it in (along with zinc, a topic for another post). Recently, I’ve been doing more digging into the actual science behind the use of magnesium for PCOS management, and surprisingly, I cannot find any studies that show a causal link between magnesium supplementation and progesterone levels in humans, although there are other studies that show magnesium levels in the body change as hormone levels change (the reverse direction of causation). But adding in magnesium and zinc seemed to help my symptoms, so let’s see how that might be.
