Hidden connection between vitamin D and contraceptive methods discovered
A Fresh Take:
Women on estrogen-based birth control pills boast higher vitamin D levels, while those who stop using such contraceptives experience a sharp drop in vitamin D reserves. Let's dive into the world of vitamin D, the key player in maintaining the ideal balance of calcium and phosphorus in our bodies.
Foods like fish and eggs brim with this vital nutrient, but 90% of our vitamin D is produced in our very own skin, thanks to a jolly ol' chemical reaction after communing with sunlight. To paint a grim picture, a lack of vitamin D can lead to bone-crunching conditions like rickets and osteomalacia (softening of bones).
Given its paramount role in our bone health, particularly during pregnancy, the team at National Institutes of Health's National Institute of Environmental Health Sciences decided it was high time to investigate the relationship between vitamin D levels and oral contraceptives.
The Vitamin D-Contraception Connection
Researchers surveyed around 1,700 African-American women between 23-34 living near Detroit, MI, regarding their contraceptive usage and time spent outdoors. participants agreed to supply blood samples to determine their 25-hydroxy vitamin D levels.
Surprisingly, the study revealed a correlation between higher vitamin D levels and the use of estrogen-based contraceptives, making these ladies a touch sunnier than the rest, even after controlling factors like seasonal exposure to sunlight.
"Women using contraception containing estrogen tend to have higher vitamin D levels than other women. Our findings suggest that contraceptives containing estrogen boost vitamin D levels, and those levels are likely to drop when ladies stop using these contraceptives," said Dr. Quaker E. Harmon.
After making adjustments for confounding variables, the use of these hormonal contraceptives was associated with a 20% hike in 25-hydroxy vitamin D levels.
As women started their journey to pregnancy, they could be at risk of developing vitamin D deficiency owing to the drop in estrogen-based contraceptive use, highlighting the importance of maintaining adequate vitamin D levels during this crucial period.
Vitamin D Deficiency in the Early Pregnancy Phase
This recent study, published in the Journal of Clinical Endocrinology & Metabolism, shines a light on the fact that women planning to stop using birth control ought to take measures to ensure their vitamin D levels are sufficient while attempting conception and during pregnancy.
Medical News Today peppered Dr. Harmon with questions, such as why estrogen-based contraception might influence vitamin D levels. She hypothesized that the presence of estrogen might lead to alterations in vitamin D metabolism, requiring further research.
Regarding race and its potential role in this association, Dr. Harmon shared that the same observation has been made in non-African American women, suggesting that race is not a key factor in this effect. Since African-American women are more prone to vitamin D deficiency, even small fluctuations in their vitamin D concentrations could hold significant consequences.
Dr. Harmon continues to monitor this group of women and is working with another group to investigate how vitamin D varies across the menstrual cycle.
