Discovered Connection: Vitamin D and Birth Control Methods Revealed
Study Reveals Link Between Estrogen-Based Birth Control and Vitamin D Levels
Researchers at the National Institutes of Health (NIH) have discovered a correlation between estrogen-based contraceptives and increased levels of vitamin D in women. This finding has significant implications for women's health, particularly during early pregnancy.
Vitamin D plays a crucial role in maintaining the correct balance of calcium and phosphorus in the blood and aiding the body's absorption of calcium, an essential component of bones. Food sources high in vitamin D include fish and eggs, while approximately 90% of the vitamin is produced in the skin after exposure to sunlight.
Dr. Quaker E. Harmon, of the NIH's National Institute of Environmental Health Sciences in Research Triangle Park, NC, led a study examining changes in vitamin D levels associated with oral contraceptives. The team analyzed data from the Study of Environment, Lifestyle, and Fibroids (SELF), an investigation into reproductive health that involved nearly 1,700 African-American women aged 23-34 living in Detroit, MI.
The study questioned women about their contraceptive use and inquired about the time they spent outside and any vitamin D supplements they took. Overall, 1,662 women provided blood samples to assess levels of the most common form of circulating vitamin D, 25-hydroxy vitamin D.
Dr. Harmon's team discovered that women using contraception containing estrogen tended to have higher vitamin D levels than other women. Even after controlling for factors such as seasonal exposure to light, this connection remained significant. The researchers could not identify any behavioral differences, like increased outdoor time, to explain this increase.
Following adjustments for confounding variables, the use of contraceptive pills, patches, or rings containing estrogen was associated with 20 percent higher levels of 25-hydroxy vitamin D. Current users of birth control exhibited higher vitamin D levels, while past users generally experienced average levels.
Women contemplating pregnancy should be aware of the potential risk of vitamin D deficiency as they discontinue estrogen-based contraceptives. Dr. Harmon suggests that taking steps to maintain adequate vitamin D levels before and during pregnancy is essential. Furthermore, she plans to continue studying this relationship, as well as investigating how vitamin D varies across the menstrual cycle.
According to research, vitamin D deficiency in early pregnancy may increase the risk of neurodevelopmental disorders like ADHD, schizophrenia, and autism in offspring. Maintaining adequate vitamin D levels during the prenatal period is, therefore, vital for both fetal brain development and maternal hormonal regulation.
In conclusion, the relationship between estrogen-based contraceptives and vitamin D levels is worth considering for healthcare providers when assessing vitamin D levels in women discontinuing estrogen contraceptives who are trying to conceive or in early pregnancy. Proper vitamin D management during this critical period reduces potential risks related to vitamin D deficiency.
