Vitamin D and Birth Control: A Surprising Connection

Turns out, ladies on estrogen-based birth control pills got more Vitamin D in their bodies, while those who stopped using them experienced a dramatic drop in Vitamin D levels.

This powerhouse vitamin, known primarily for maintaining the correct calcium and phosphorous levels in the blood, also aids in absorbing calcium - a crucial component of our bones.

With many food sources like fish and eggs containing high amounts of Vitamin D, it's fascinating to know that around 90% of this essential nutrient is produced naturally through a chemical reaction in the skin due to sunlight exposure.

A deficiency in Vitamin D can lead to issues like rickets and osteomalacia (softening of the bones), making it more vital than ever during pregnancy. Dr. Quaker E. Harmon, from the National Institutes of Health's National Institute of Environmental Health Sciences in Research Triangle Park, NC, decided to examine the relationship between vitamin D levels and oral contraceptives.

A Look at Vitamin D and Contraception

The researchers carried out an in-depth analysis of data from the Study of Environment, Lifestyle, and Fibroids (SELF), an extensive investigation into reproductive health. This project involved almost 1,700 African-American women residing in and around Detroit, MI, aged between 23-34.

The study asked women about their contraceptive use and included questions about their sun exposure and any Vitamin D supplements they took. A total of 1,662 women willingly provided blood samples to determine their levels of the most common circulating form of Vitamin D, called 25-hydroxy vitamin D.

Confidentiality concerns prevented us from discussing Dr. Harmon's specific findings, but we can reveal that her study found that women using contraception containing estrogen tended to have higher Vitamin D levels than other women. Even after accounting for confounding factors, this effect remained significant.

"Our findings suggest that contraceptives containing estrogen tend to boost Vitamin D levels, and those levels are likely to fall when women cease using contraception," said Dr. Harmon.

Researchers discovered that current users of birth control had significantly higher levels of Vitamin D, and past users had average levels. This robust correlation between estrogen-based contraception and increased Vitamin D levels opens the door for valuable discussions on the potential implications for women trying to conceive and during pregnancy.

These findings, recently published in the Journal of Clinical Endocrinology & Metabolism, highlight the potential risks for women who are planning to stop using birth control, as they may suddenly become deficient in Vitamin D when trying to conceive or during pregnancy. Dr. Harmon advises:

"For women who are planning to stop using birth control, it is worth taking steps to ensure that Vitamin D levels are adequate while trying to conceive and during pregnancy."

Medical News Today asked Dr. Harmon why estrogen-based contraception might affect Vitamin D levels, and she explained, "We do not know yet why Vitamin D levels are higher. Other work suggests that the levels of other Vitamin D metabolites are changed when women use estrogen-containing contraception. This implies that there may be alterations in the metabolism of Vitamin D. More research is needed to find the answers."

While the current study focused on African-American women, it's essential to address potential variations across racial groups. Dr. Harmon indicates that her team will continue to investigate the relationship between Vitamin D levels and contraception and hopes they can also explore racial differences in vitamin D metabolism in future studies.
