Vitamin D and Gene Expression: A Master Example of Nutrigenomics
Dr. Kumar’s Take:
Vitamin D is much more than just a nutrient for bone health—it acts as a powerful regulator of gene expression, influencing metabolism, immunity, and cellular health. This study highlights how vitamin D interacts with our DNA through the vitamin D receptor (VDR), making it a prime example of nutrigenomics. For optimal health, individuals should monitor their vitamin D levels and consider personalized supplementation, especially those who may be “low responders” to standard doses.
