Uncovered connection discovered between vitamin D and contraception in new study
Revised Article:
Hey there! Let's dive into the fascinating connection between estrogen-based birth control and vitamin D levels in women.
Folks taking estrogen-based birth control pills may have elevated vitamin D levels compared to those not on these contraceptives. Surprisingly, women who stop using these pills might experience a significant drop in vitamin D levels.
Vitamin D, often dubbed the 'sunshine vitamin,' plays a crucial role in maintaining the correct calcium and phosphorus levels in the blood. It's also responsible for helping our bodies absorb calcium, a key component of our bones. While foods like fish and eggs are high in vitamin D, around 90% of it is produced naturally in our skin through sunlight exposure.
A lack of vitamin D can lead to problems like rickets and osteomalacia (softening of the bones), making it particularly important during pregnancy due to the role it plays in creating a healthy baby's skeleton.
Dr. Quaker E. Harmon, from the National Institutes of Health's National Institute of Environmental Health Sciences, decided to investigate the relationship between vitamin D levels and oral contraceptives.
Linking estrogen-based contraception and vitamin D
Using data from the Study of Environment, Lifestyle, and Fibroids (SELF), a research project focused on reproductive health, Dr. Harmon and his team analyzed almost 1,700 African-American women aged 23-34 living in and around Detroit, MI. The study gathered information about contraceptive use, sun exposure, and any vitamin D supplements taken.
Out of the participants, 1,662 women provided blood samples to measure their 25-hydroxy vitamin D levels, the most common form of vitamin D in circulation.
The study found that women using contraceptives containing estrogen tended to have higher vitamin D levels than other women. Even after accounting for factors like seasonal sunlight exposure, the difference remained significant. Dr. Harmon and his team could not find any behavioral explanations for the increase, suggesting that estrogen-based contraception may boost vitamin D levels.
After making adjustments for confounding variables, using contraceptive pills, patches, or rings containing estrogen was associated with 20% higher levels of 25-hydroxy vitamin D. Current users of these contraceptives had higher vitamin D levels, while past users had average levels.
Vitamin D deficiency during early pregnancy
This research, published in the Journal of Clinical Endocrinology & Metabolism, raises concern for future pregnant women, as they may become vitamin D deficient as they begin trying to conceive. Dr. Harmon recommends taking steps to ensure adequate vitamin D levels during this time.
When asked about the possible reasons for the increased vitamin D levels in women using estrogen-based contraceptives, Dr. Harmon mentioned that further research is needed to fully understand the metabolism of vitamin D when using these contraceptives.
The study only looked at African-American women; however, Dr. Harmon believes the association is not linked to race. In the United States, African-American women are more likely to be vitamin D-deficient, making even minor vitamin D increases or decreases more significant. Dr. Harmon is also continuing to follow the women in the study to gain a better understanding of the relationship.

Enrichment Insights:- Maintaining adequate vitamin D levels is generally recommended for overall health, including bone health and potentially other aspects of women's health.- During menopause, estrogen levels decline, which can accelerate aging processes.- Pregnancy involves significant hormonal changes, but the specific interaction between estrogen-based contraceptives, vitamin D, and pregnancy remains to be fully understood.- While the research results do not provide a direct link between estrogen-based contraceptives and vitamin D levels during pregnancy, maintaining healthy vitamin D levels is beneficial during pregnancy.
- Dr. Harmon's research on the Study of Environment, Lifestyle, and Fibroids (SELF) suggests that estrogen-based contraceptives might boost women's vitamin D levels.
- The study found that women using contraceptives containing estrogen had 20% higher levels of 25-hydroxy vitamin D, the most common form of vitamin D in circulation.
- The association between vitamin D levels and oral contraceptives is not believed to be linked to race, but African-American women are a more vulnerable population prone to vitamin D deficiencies.
- As estrogen-based contraceptive users may have higher vitamin D levels, further research is needed to fully understand the metabolism of vitamin D when using these contraceptives.
- Adequate vitamin D levels during early pregnancy are critical for the health of the growing baby's skeleton, making it essential for women to maintain their vitamin D levels before conceiving.
- Overall, maintaining adequate vitamin D levels contributes to one's health and wellness, particularly in the context of women's health, with potential benefits including stronger bones and possibly reduced risk of certain cancers.
