Explored connection between vitamin D and contraception methods revealed
A Fresh Take on Vitamin D and Contraception
Unraveling the Link Between Estrogen-Based Birth Control and Vitamin D
Embarking on a fascinating exploration, research signals a connection between estrogen-based contraceptive pills and vitamin D levels. Here's a streamlined rundown of this intriguing discovery.
Vitamin D: Securing the correct balance of calcium and phosphorous in the blood, this vital nutrient also aids in absorbing calcium— essential for developing strong bones. Besides absorbing calcium, an impressive array of foods like fish and eggs provides a substantial dose of vitamin D, while 90% of it is produced by the body through a chemical reaction initiated by sun exposure.
Deficiency of this crucial nutrient induces issues such as rickets and osteomalacia (softening of the bones) and during pregnancy, its significance is amplified as the body requires adequate levels to facilitate fetal bone development.
Intrigued by the correlation between oral contraceptives and vitamin D levels, Dr. Quaker E. Harmon, from the National Institutes of Health's National Institute of Environmental Health Sciences, delved into an investigation.
A Closer Look at Vitamin D & Contraception
The research team upheld a cross-sectional analysis using data from the Study of Environment, Lifestyle, and Fibroids— a project centered on reproductive health. Conducting their study on nearly 1,700 African-American women residing in and around Detroit, MI, aged between 23-34, they delved into contraceptive usage, time outdoors, and any vitamin D supplements they consumed.
According to lab analysis, 1,662 women provided blood samples for vitamin D level determination. During pregnancy, the body produces increased amounts of the active form of vitamin D, elevating the risk of deficiency and associated bone problems.
"We observed that women using contraception containing estrogen exhibited higher levels of vitamin D than other participants."

Despite accounting for confounding factors such as seasonal sunlight exposure, the association remained noteworthy. "We didn't detect any lifestyle differences to explain the increase," stated Dr. Harmon. "This suggests that contraceptives containing estrogen contribute to elevated vitamin D levels, which could decrease when women cease contraceptive use."
Upon factoring in confounding variables, estrogen-based contraceptive pill, patch, or ring users experienced 20% higher levels of circulating vitamin D. Those using the contraceptives had higher vitamin D levels, while past users averaged normal vitamin D levels.
Vitamin D Insufficiency in Early Pregnancy
These findings published in the Journal of Clinical Endocrinology & Metabolism indicate that women planning to conceive while off birth control might experience vitamin D deficiency. Dr. Harmon offers the following advice:
"It may be wise for women discontinuing birth control to consider steps ensuring adequate vitamin D levels as they try to conceive and during pregnancy."
While this research concentrates on African-American women, Dr. Harmon clarifies:
"This association has been observed among young and older women who are not African-American, implying that the association does not seem to stem from race."
Continuing her work, Dr. Harmon will follow this group to probe further into their relationship, as well as engage another group to investigate how vitamin D varies along the menstrual cycle.
Also, explore research highlighting how higher vitamin D levels potentially decrease the risk of cancer.
Background insights: While the link between estrogen-based contraception and vitamin D remains under-researched, potential explanations include estrogen impacting vitamin D metabolism and regulation, and alterations in vitamin D-binding proteins. These findings have important implications for women's reproductive health and pregnancy nutrition.
- The connection between estrogen-based contraceptive pills and vitamin D levels is being explored in science, particularly concerning the impact on women's health and nutrition.
- A study conducted by Dr. Quaker E. Harmon, involving African-American women, revealed that those using contraceptives containing estrogen exhibited higher levels of vitamin D compared to others.
- Upon accounting for confounding factors and seasonal sunlight exposure, estrogen-based contraceptive pill, patch, or ring users experienced 20% higher levels of circulating vitamin D.
- Dr. Harmon advises women discontinuing birth control to consider ensuring adequate vitamin D levels, as those planning to conceive might experience vitamin D deficiency.
- These findings hint at a broader association that does not seem to stem from race, as similar observations have been made among young and older women who are not African-American.
- With additional research, science may uncover the potential link between higher vitamin D levels and decreased risk of cancer, which could significantly impact women's health and wellness.
