Estrogen-Based Contraceptives and Vitamin D Levels: What Women Need to Know
Turns out, ladies, the estrogen-based pills you pop for birth control might be influencing your vitamin D levels. Researchers have discovered that women using estrogen contraception have higher vitamin D levels, while those who stop using these meds experience a significant drop in D levels.
Vitamin D plays a vital role in maintaining the right balance of calcium and phosphorous in the blood. It also aids in the body's absorption of calcium, which is crucial for strong bones. According to the experts, food sources like fish and eggs are rich in vitamin D, but about 90% of our D comes from sunlight exposure. Deficiency in this essential nutrient can lead to bone conditions like rickets and osteomalacia.
Since vitamin D is critical during pregnancy, it's necessary to pay attention to D levels since they tend to increase during pregnancy to support the fetal skeleton's growth. However, that increase makes pregnant women more susceptible to vitamin D deficiency and related bone issues.
Wondering why estrogen-based contraception affects vitamin D levels? Dr. Quaker E. Harmon, from the National Institutes of Health's National Institute of Environmental Health Sciences, decided to investigate.
Vitamin D and Contraception: A Closer Look
To dig deeper into the connection between contraception and vitamin D, Dr. Harmon and her team analyzed data from the Study of Environment, Lifestyle, and Fibroids (SELF), a research project focusing on reproductive health. Nearly 1,700 African-American women aged 23-34 living around Detroit, MI were surveyed about their contraceptive use, time spent outside, and vitamin D supplements.
Overall, 1,662 women provided blood samples for the study, allowing researchers to measure levels of the most common circulating form of vitamin D known as 25-hydroxy vitamin D.
Dr. Harmon and her team found that women using estrogen-based contraceptives had higher vitamin D levels compared to other women. After controlling for confounding variables such as seasonal exposure to sunlight, the association remained strong. Interestingly, they couldn't find any behavioral differences, like increased time spent outdoors, to explain the increase in vitamin D levels.
20 Percent Boost: The Impact of Hormonal Contraceptives
After analyzing the data, they discovered that women using contraceptive pills, patches, or rings containing estrogen had 20 percent higher levels of 25-hydroxy vitamin D. Meanwhile, past users demonstrated average vitamin D levels.
These findings, published in the Journal of Clinical Endocrinology & Metabolism, suggest that women could develop vitamin D deficiency as they start trying to conceive or during pregnancy. Dr. Harmon recommends taking steps to ensure vitamin D levels are sufficient during that period.
However, Dr. Harmon couldn't pinpoint exactly why estrogen-based contraception affects vitamin D levels. She speculates that it may interfere with the metabolism or absorption of vitamin D, although more research is needed to confirm this theory.
The study focused solely on African-American women, but Dr. Harmon mentioned that the same association has been observed in women of other races. Furthermore, she plans to continue monitoring the women enrolled in the study and is working on another group to investigate how vitamin D varies throughout the menstrual cycle.

Caveats:
- Estrogen-based contraception like birth control pills, patches, or rings might deplete vitamin D levels over extended usage, which could be a significant concern for those at a higher risk of vitamin D deficiency, such as African-American women.
- The reasons for this effect are unclear, but it's believed that hormonal contraceptives could affect the metabolism or absorption of vitamin D.
- Maintaining adequate vitamin D levels is essential for bone health and overall well-being, so it's crucial to monitor levels and consider supplementation if necessary.
- Consult a healthcare provider for personalized advice on managing potential vitamin D deficiencies.
- Supplements like vitamin D3 and lifestyle changes like dietary modifications, reduced alcohol consumption, and increased sunlight exposure can help minimize vitamin D deficiencies.
- Women using estrogen-based contraception have higher vitamin D levels compared to others, according to a research study.
- A significant drop in vitamin D levels is observed in women who stop using estrogen contraception.
- Vitamin D deficiencies can lead to bone conditions like rickets and osteomalacia, making it crucial for women to maintain sufficient levels, particularly during pregnancy.
- The SELF study, focusing on reproductive health, discovered a 20% boost in 25-hydroxy vitamin D levels among women using estrogen-based contraceptives.
- Studies have indicated that the same association between vitamin D levels and estrogen-based contraception exists in women of various races.
- Maintaining proper vitamin D levels is important for overall health and wellness in women, and seeking advice from a healthcare provider can help manage potential deficiencies.
