Can Chemical Exposure Affect Your Vitamin D Level?

Recent research published in the Journal of Clinical Endocrinology and Metabolism concluded that exposure to bisphenol A (BPA) and other endocrine-disrupting chemicals (EDC’s) may reduce levels of vitamin D in the bloodstream. EDC’s are chemicals that interfere with hormones in the body and can have adverse health effects.

The review included over 1,300 studies that found links between chemical exposure and health problems including infertility, obesity, diabetes, neurological problems and hormone-related cancers. In the study 4.667 adults previously in a national survey between 2005 and 2010 in which participants provided blood samples so their vitamin D level could be measured, and urine samples to evaluate EDC exposure or specifically substances left behind after the body metabolized BPA and phthalates. Results showed that people exposed to larger amounts of phthalates were more likely to have low levels of vitamin D in the bloodstream that subjects who were exposed to smaller amounts of EDC’s and this was stronger in women., The researchers also found an association between exposure to higher levels of BPA and reduced vitamin D levels in women but the relationship was not statistically significant in men. Researchers acknowledged that more research was needed. EDC’s are found in everyday products and throughout the environment and vitamin D levels have been implicated in outcomes of numerous conditions such as cardiovascular disease, diabetes, and cancer.
