How are VDR and Langlebigkeit related?

The vitamin D receptor (VDR) is a nuclear receptor activated by calcitriol, regulating genes involved in calcium homeostasis, immune function, cell proliferation, and inflammation. Some observational studies suggest that common VDR polymorphisms (e.g., rs2228570, rs1544410) may be associated with altered receptor activity and potentially with longevity-related outcomes such as bone health, immune aging, and cancer risk. However, the evidence is mostly observational and inconsistent; effect sizes are small, and lifestyle factors (diet, sun exposure, exercise) dominate. No robust RCTs demonstrate a direct causal link between VDR variants and human lifespan. Therefore, a DNA test for VDR alone cannot predict longevity. MyBody-X is not a medical diagnostic tool. For personalized advice on vitamin D or bone health, consult a healthcare professional.
