Unearthed connection between vitamin D and contraceptive methods revealed
Finding the Link between Estrogen-based Contraceptives and Vitamin D Levels
Turns out, there's a surprising connection between estrogen-based birth control pills and vitamin D levels in women. According to a recent study, women who are on these contraceptives tend to have higher quantities of vitamin D, while those who stop using them experience a significant drop.
The Essential Role of Vitamin D
Vitamin D is no stranger to its role in maintaining the balance of calcium and phosphorous in our bloodstream. Moreover, it assists our bodies in absorbing calcium—a vital component for strong bones. Foods like fish and eggs are notorious for being high in vitamin D, but most of it (about 90%) is naturally produced in our skin following exposure to sunlight.
Vitamin D deficiency can lead to health issues such as rickets and osteomalacia, which results in the softening of bones. Given its importance in bone formation, it's crucial during pregnancy, as a deficiency increases the risk of developing bone problems.
The Connection Unveiled
Determined to uncover any connections between contraceptives and vitamin D levels, Dr. Quaker E. Harmon from the National Institutes of Health's National Institute of Environmental Health Sciences investigated 1,662 African-American women aged 23-34 from Detroit, MI. Participants revealed contraceptive use, time spent outdoors, and vitamin D supplements taken.
The study found that women using estrogen-based contraception had higher vitamin D levels than other women, even after adjusting for confounding factors like seasonal exposure to light. Dr. Harmon and her team attribute this increase to the estrogen in the contraceptives, though why this is remains unclear.
When examining the data, the research discovered that current users of birth control had higher vitamin D levels, while past users displayed average levels. This suggests that estrogen-based contraceptives might boost vitamin D levels, and those levels may fall upon stopping usage.
What This Means for Women Planning Pregnancy
The findings, published in the Journal of Clinical Endocrinology & Metabolism, suggest that women planning to become pregnant should be aware of the potential risk of vitamin D deficiency. Dr. Harmon advises taking steps to ensure adequate vitamin D levels while trying to conceive and during pregnancy.
While the study focused solely on African-American women, Dr. Harmon believes the relationship between estrogen-based contraceptives and vitamin D levels is not related to race. In the United States, African-American women are more likely to be vitamin D-deficient, so even small increases or decreases in their vitamin D concentrations may have significant implications.
The Future of Research
Dr. Harmon continues to work with this group of women to investigate the relationship further and is also studying another group to determine how vitamin D varies across the menstrual cycle. She is dedicated to discovering more about this intriguing connection between estrogen-based contraceptives and vitamin D.

- Despite popular beliefs, vitamin D plays a crucial role in various aspects of women's health beyond just bone formation, such as hormone balance and immune function.
- The science of health-and-wellness reveals that multi-vitamins, specifically women's multivitamins, can be an essential part of ensuring adequate nutrient intake, particularly for women facing deficiencies in key nutrients like vitamin D.
- It is noteworthy that cultural factors can influence the prevalence of nutrient deficiencies, with African-American women often at an increased risk of vitamin D deficiency due to various factors like limited sun exposure and traditional diets.
- Furthermore, research in the field of women's health and nutrition indicates a connection between estrogen-based contraceptives and higher vitamin D levels in women, which can have an impact on their overall health and well-being.
- Healthcare providers and women planning pregnancy should be aware of the potential link between estrogen-based contraceptives and vitamin D levels, and take steps to ensure vitamin D sufficiency during conception and pregnancy.
- Scientific research continues to explore the complex relationship between estrogen-based contraceptives, vitamin D levels, and women's health, with hopes of gaining a better understanding of this intriguing connection and its implications for women's health and wellness.
