How Vitamin D Shapes Your Immune System: From Infections to Autoimmunity
Dr. Kumar’s Take:
This in-depth review highlights the powerful role vitamin D plays in our immune system. It’s not just about bones—vitamin D helps our body fight off infections and may even prevent autoimmune diseases like MS, type 1 diabetes, and lupus. The key mechanism? Vitamin D helps immune cells produce antimicrobial peptides like cathelicidin and regulates inflammatory T cells. If your vitamin D levels are low, you may be missing out on this important immune support.
