Vitamin D and Fertility

This is not turning into the “In praise of Vitamin D Blog,” I promise you, but it seems like a lot of Vitamin D related news is coming out lately. I have taken Vitamin D since 2004 when I read about the relationship between sunlight and cancer (sunnier regions have less cancer). Now, a study shows a correlation between low vitamin D levels and infertility. As my psychology professors always hammered home “correlation doesn’t show causation,” but nonetheless, this is rather interesting.

In a recent study of infertile women, 90% had vitamin D deficiencies. Also from the authors of the study:

Of note, not a single patient with either ovulatory disturbance or polycystic ovary syndrome demonstrated normal Vitamin D levels

Yet another reason to try Vitamin D.
