Explored relationship exposed between vitamin D and contraceptive methods
"Vitamin D Levels and Birth Control: A Fascinating Connection"
Vitamin D, the sunshine vitamin, plays a crucial role in maintaining the correct balance of calcium and phosphorus in our blood and aiding in the absorption of calcium, a vital component of bones. Foods like fish, eggs, and sunlight are abundant sources of this essential nutrient.
But here's where things get interesting! Research has shown that women taking estrogen-based birth control pills could have higher levels of circulating vitamin D compared to those not using these contraceptives. On the flip side, women who stop taking these pills might experience a significant drop in their vitamin D levels.
Dr. Quaker E. Harmon, from the National Institutes of Health's National Institute of Environmental Health Sciences, was intrigued by this finding and decided to delve deeper.
The Link Between Vitamin D and Contraceptives
To investigate the association, Dr. Harmon and her team conducted a study using 1,662 African-American women from the Study of Environment, Lifestyle, and Fibroids. The research aimed to understand any changes in vitamin D levels linked with taking oral contraceptives.
The study explored participants' contraceptive use and factors such as time spent outdoors and vitamin D supplements taken. Blood samples were collected to ascertain levels of 25-hydroxy vitamin D, the most common circulating form of vitamin D.
The findings were striking! Women using contraception containing estrogen exhibited higher vitamin D levels. Even when controlling for confounding factors, such as seasonal exposure to light, the effect remained significant. current and past users of birth control had higher levels of vitamin D compared to non-users.
With this insight, it's essential for women planning to stop using birth control to ensure their vitamin D levels are adequate before conceiving and during pregnancy.
But why does estrogen-based contraception affect vitamin D levels? While the exact mechanism is not yet clear, studies suggest that changes in vitamin D metabolism may occur when women use estrogen-containing contraception. Further research is needed to fully understand this complex relationship.
It's worth noting that this study focused solely on African-American women, but the same association has been observed in women of diverse races. As African-American women are more likely to be vitamin D-deficient, even small increases or decreases in their vitamin D concentrations can be significant.
Dr. Harmon continues her research, monitoring this group of women to further investigate the relationship and working on a new group of participants to explore how vitamin D varies across the menstrual cycle. Discover more about research showing that higher vitamin D levels may lower cancer risk!
