Unearthed connection between vitamin D and contraception potentially significant
Galavanting Through Sunlight and Pills: A look at Vitamin D and Birth Control
Jump aboard this fascinating voyage as we delve into the intriguing relationship between Vitamin D and birth control pills. It turns out that the hormonal dance between these two players plays a significant role in maintaining your bone health.
Vitamin D, the almighty bone-strengthener, keeps your calcium and phosphorous levels in check, ensuring your bones remain rock-solid. Most of this vital nutrient is naturally produced in your skin after being kissed by the sun, though it can also be found in foods like fish and eggs.
Vitamin D deficiency has some serious consequences, causing issues such as rickets and osteomalacia (softening of the bones). Given its crucial role in bone formation, Vitamin D is especially important during pregnancy. That's why Dr. Quaker E. Harmon, from the National Institute of Environmental Health Sciences (NIH), decided to investigate any links between vitamin D levels and oral contraceptives.
Dancing Hormones: Vitamin D and Contraception
Dr. Harmon's team conducted a study on 1,662 African-American women living around Detroit, aged 23-34. They asked participants about their contraceptive use, time spent outdoors, and Vitamin D supplements, and collected blood samples to measure vitamin D levels.
After analyzing the data, Dr. Harmon's team found that women using contraception containing estrogen had higher vitamin D levels than others. Even after accounting for factors like seasonal exposure to light, this effect remained significant.
"Our study found that women who were using contraception containing estrogen tended to have higher vitamin D levels than other women."

Since women produce increased levels of the active form of vitamin D during pregnancy, they face a higher risk of deficiency. Therefore, any boost to vitamin D levels from estrogen-based contraceptives could be significant.
"We could not find any behavioral differences such as increased time spent outdoors to explain the increase," said Dr. Harmon. "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."
After adjusting for confounding variables, the use of contraceptive pills, patches, or rings containing estrogen was linked to a 20% increase in vitamin D levels. Women currently using birth control had higher vitamin D levels, while past users had average levels.
The Pregnant Dance: Vitamin D Deficiency in Early Pregnancy
These findings, published in the Journal of Clinical Endocrinology & Metabolism, hint that women starting their pregnancy journey might be at risk of vitamin D deficiency. Dr. Harmon advises women planning to stop using birth control to ensure their vitamin D levels are adequate during conception and pregnancy.
While the study focused exclusively on African-American women, Dr. Harmon believes that the association is not related to race. In fact, she will continue following the women in the study to investigate the relationship further. Additionally, she is working on another group of participants to study how vitamin D varies across the menstrual cycle.
So, there you have it! Embrace the sunlight, fuel your diet with vitamin D-rich foods, and keep a watchful eye on your vitamin D levels if you're using estrogen-based contraceptives, especially as you embark on your pregnancy journey. Stay curious, my friends, because there's always more to discover!
- "The study conducted by Dr. Quaker E. Harmon's team focused on African-American women and investigated the relationship between vitamin D levels and oral contraceptives."
- "Intriguingly, the research found that women using contraception containing estrogen had higher vitamin D levels compared to other women."
- "These increased vitamin D levels remained significant even after accounting for factors like seasonal exposure to light."
- "Pregnant women, who produce increased levels of the active form of vitamin D, face a higher risk of deficiency, making the boost from estrogen-based contraceptives potentially significant."
- "To mitigate the risk of vitamin D deficiency during conception and pregnancy, Dr. Harmon advises women planning to stop using birth control to ensure their vitamin D levels are adequate."
- "The association between contraceptives containing estrogen and increased vitamin D levels may not be race-specific, as Dr. Harmon plans to continue investigating the relationship further, expanding her research to include a diverse group of participants."
