How are VDR and Stress related?

The provided context does not directly address the relationship between VDR (Vitamin D Receptor) and stress. In general, VDR is involved in regulating genes related to immune function, inflammation, and calcium metabolism—processes that can influence the hypothalamic-pituitary-adrenal (HPA) axis and stress response. Some studies suggest associations between VDR polymorphisms and stress susceptibility or cortisol levels, but effect sizes are small and findings inconsistent. The evidence is mostly mechanistic or observational. Consumer DNA tests often overstate such links. Without robust clinical trials or meta-analyses, clinical relevance remains unclear. Ensuring adequate vitamin D status is generally beneficial, but targeted lifestyle changes based solely on VDR genotype are not currently evidence-based.
