Unveiled discovery: Potential link found between vitamin D levels and contraception effectiveness
Estrogen-Based Birth Control and Vitamin D Levels
Got questions about estrogen-based birth control and its impact on your vitamin D levels? We've got the scoop!
Let's start with the basics: Vitamin D is an essential nutrient that plays a vital role in maintaining healthy bones by regulating calcium levels in your body. It's found naturally in certain food sources like fish and eggs (yum!), but around 90% of your vitamin D is produced in your skin after exposure to sunlight.
A fascinating study led by Dr. Quaker E. Harmon, a researcher from the National Institutes of Health's National Institute of Environmental Health Sciences, has shed some light on a connection between estrogen-based birth control and vitamin D levels.
Vitamin D and Contraception
The research team analyzed data from the Study of Environment, Lifestyle, and Fibroids (SELF), a comprehensive investigation of reproductive health, involving almost 1,700 African-American women living in and around Detroit, MI, aged 23-34. The study asked women about their contraceptive use and included questions about outdoor time and any vitamin D supplements taken.
Out of these participants, 1,662 women provided blood samples to measure their levels of 25-hydroxy vitamin D, the most common circulating form of vitamin D. The study found that women using contraception containing estrogen tended to have higher vitamin D levels than other women.
After accounting for factors like seasonal exposure to light, the increased vitamin D levels remained significant. The researchers couldn't find any behavioral differences to explain the increase, suggesting that estrogen-based contraception is likely boosting vitamin D levels.
Vitamin D Deficiency and Pregnancy
With pregnancy, women produce increased levels of the active form of vitamin D to support the growth of the fetal skeleton. As a result, pregnant women have an increased risk of vitamin D deficiency, and subsequently, a higher risk of developing bone problems.
Dr. Harmon advises women who are planning to stop using birth control to ensure their vitamin D levels are adequate while trying to conceive and during pregnancy.
So, what's behind this fascinating connection? Dr. Harmon noted that the link between estrogen-based contraception and vitamin D levels could be due to changes in vitamin D metabolism. More research is needed to fully understand this intriguing relationship.
It's important to note that this study focused on African-American women. Dr. Harmon stated that similar associations have been observed in other demographic groups, hinting that the observed effects might not be related to race.
Stay tuned for more research on the relationship between vitamin D and estrogen-based contraception! Remember, maintaining adequate vitamin D levels is essential for overall health, especially during pregnancy. So, talk to your doctor, monitor your levels and consider supplementation if necessary.

- Estrogen-based birth control has been linked to higher vitamin D levels according to a study led by Dr. Quaker E. Harmon, which analyzed data from thousands of women of various demographics.
- The enhancement in vitamin D levels is significant even when factors like seasonal exposure to light are considered, indicating that estrogen-based contraception might influence vitamin D metabolism.
- Maintaining adequate vitamin D levels is crucial for overall health, particularly during pregnancy due to increased demands for supporting fetal bone growth.
- It's advisable for women planning to discontinue birth control to ensure they have proper vitamin D levels while trying to conceive and during pregnancy.
- The study, while focused on African-American women, has observed similar associations in other demographic groups, suggesting that the observed effects might not be related to race.
- As science continues to uncover the relationship between vitamin D and estrogen-based contraception, it's essential to discuss vitamin D levels with your healthcare professional, monitor your levels, and consider supplementation if necessary for overall health and women's health.
