Exploring the fascinating connection between vitamin D supplementation and hormonal birth control methods revealed
Why estrogen-based birth control may impact your vitamin D levels:
Turns out, estrogen-infused birth control pills, patches, or rings can significantly influence your vitamin D levels. According to a recent study, women using these contraceptives tend to have higher levels of this essential nutrient compared to others. Dr. Quaker E. Harmon, a researcher from the National Institutes of Health's National Institute of Environmental Health Sciences, led the investigation.
The study, published in the Journal of Clinical Endocrinology & Metabolism, used data from the Study of Environment, Lifestyle, and Fibroids (SELF), an exploration of reproductive health. The project surveyed nearly 1,700 African-American women residing in and around Detroit, MI, aged between 23-34.
The survey questioned participants about their contraceptive choices and included questions regarding time spent outdoors and any vitamin D supplements consumed. In the end, 1,662 women donated blood samples to determine their levels of 25-hydroxy vitamin D, the most common circulating form of the vitamin.
During pregnancy, women's bodies produce more of the active form of vitamin D to support the growth of the fetal skeleton. As a result, pregnant women are at a higher risk of vitamin D deficiency, which boosts the likelihood of developing bone issues.
"Our study found that women taking contraception containing estrogen had higher vitamin D levels than other women," explained Dr. Harmon. The effect remained significant even after controlling for factors like seasonal exposure to sunlight. Dr. Harmon and her team were unable to pinpoint any significant differences in behavior, such as increased outdoor time, that could explain the increase.
After adjusting for confounding variables, estrogen-based contraceptive users experienced a 20 percent higher level of 25-hydroxy vitamin D. Current users displayed higher vitamin D levels, while past users had average levels.
When a woman decides to start trying for a baby, she could be at risk of developing a vitamin D deficiency. This study suggests it may be beneficial for women planning to stop using birth control to ensure their vitamin D levels are adequate while attempting conception and during pregnancy.
While the study focused solely on African-American women, the same association has been observed in various populations, suggesting that this relationship might not be race-specific. In the United States, African-American women are more likely to be vitamin D-deficient; small increases or decreases in their vitamin D concentrations may have a larger impact.
The study's findings also prompt Dr. Harmon to continue investigating the relationship, tracking the same group of women further and studying another group to examine how vitamin D varies across the menstrual cycle.
Although the specific reasons underlying the estrogen-vitamin D link remain unclear, it's vital to maintain an adequate vitamin D level to support overall health, especially during pregnancy. If you have concerns about your vitamin D levels, consult your healthcare provider.
Interesting fact: While sunlight exposure and vitamin D-rich foods contribute to vitamin D production, around 90 percent of the essential nutrient is generated through a chemical reaction in the skin.
