Vitamin D Deficiency Increases Autoimmune Risk.

Vitamin D plays a crucial role in regulating inflammation and recognizing harmful cells in the body. Vitamin D deficiency (VDD) is prevalent among autoimmune disease populations, including rheumatoid arthritis, lupus, multiple sclerosis, and diabetes. Maintaining healthy vitamin D levels is key to promoting immune function and overall health. Taking a high-quality vitamin D supplement is the best way to reach and sustain healthy vitamin D status.
