Why is Vitamin D added to milk?

Vitamin D is added to milk primarily to promote the development of healthy bones and teeth. This vitamin plays a crucial role in calcium absorption, which is vital for maintaining proper bone density and strength. During childhood, proper nutrition is essential as this is a critical period for skeletal development. Fortifying milk with Vitamin D helps to ensure that children receive adequate amounts of this important nutrient, especially in regions where sunlight exposure, a natural source of Vitamin D, may be limited.

In addition to its role in bone health, Vitamin D also supports overall immune function and can help prevent conditions such as rickets, which is characterized by weak or soft bones in children due to a deficiency of Vitamin D, calcium, or phosphate. Thus, adding Vitamin D to milk not only enhances its nutritional profile but also contributes significantly to the long-term health and well-being of growing children.
