Vitamin D: A Role Beyond Rickets

Beyond its classical role in calcium metabolism and bone health, vitamin D serves numerous non-classical functions crucial for overall well-being. It modulates immune function, influencing both innate and adaptive immunity, thereby aiding in the prevention of infections and autoimmune diseases. Vitamin D also plays a role in regulating cellular growth and differentiation, impacting processes such as cell proliferation and apoptosis, which are essential for maintaining tissue homeostasis and preventing cancer development. Additionally, emerging evidence suggests its involvement in cardiovascular health, insulin secretion, and neurological function. These non-classical functions highlight the importance of adequate vitamin D levels for overall health beyond bone strength.
