Discovered connection between vitamin D levels and birth control methods
Rollin' with the Ds: A Fascinating Detour into Vitamin D and Birth Control
Vitamin D, sunshine's sidekick, plays a pivotal role in maintaining the correct balance of calcium and phosphorus in the body. It's a superhero that helps the body absorb calcium, an vital component of bone health. Sources of vitamin D are plentiful, with fish, eggs, and the great outdoors being our top picks. But we've got skin in the game too – a whopping 90% of our vitamin D is produced here!
Vitamin D deficiency can spell trouble, leading to conditions like rickets and osteomalacia, which translate to soft, weak bones. Given its crucial part in bone formation, vitamin D's importance during pregnancy is paramount.
Intrigued by the connection between contraceptives and vitamin D levels, scientists led by Dr. Quaker E. Harmon of the National Institutes of Health embarked on a journey. They dug into data from the Study of Environment, Lifestyle, and Fibroids, which focused on reproductive health. A total of 1,662 African-American women from the Detroit area aged 23-34 shared valuable insights, including their contraceptive use, time spent outdoors, and vitamin D supplement consumption.
Analysis of the women's blood samples revealed higher vitamin D levels in those using estrogen-based contraceptives. Even after adjusting for external factors, the link remained significant, with the use of contraceptive pills, patches, or rings associated with a staggering 20% increase in 25-hydroxy vitamin D levels.
"It seems contraceptives containing estrogen give a boost to vitamin D levels," mused Dr. Harmon. The mystery surrounding the relationship between estrogen and vitamin D remains, with scientists theorizing that estrogen may affect the metabolism of vitamin D.
As women start trying for a baby, vitamin D deficiency could be a potential risk. Dr. Harmon advises that women planning to stop using birth control consider taking steps to ensure they have an adequate vitamin D status while trying to conceive and during pregnancy.
This study only focused on African-American women; so, what role does race play in this equation? Dr. Harmon believes that this association is not race-related, as similar findings have been observed in women of diverse backgrounds. Given the higher incidence of vitamin D deficiency in African-American women in the U.S., even small changes in vitamin D levels could make a meaningful difference.
Dr. Harmon is continuing to investigate this group of women and working on another study to examine how vitamin D levels vary throughout the menstrual cycle.

Aside from containing tantalizing hints about the interplay between estrogen, contraception, and vitamin D, this study underscores the importance of maintaining good vitamin D levels – particularly for women of color who are more susceptible to deficiencies. As always, knowledge is power – and in this case, it's a powerhouse team of vitamin D and estrogen keeping us on our toes! [1][3][4]
