What mineral is milk generally deficient in?

Milk is generally deficient in iron. While milk is an excellent source of several vital nutrients, including calcium and vitamin D, it has low levels of iron. This is significant, especially for certain populations such as infants and young children, who may require additional iron sources to prevent deficiencies that can lead to health issues like anemia.

Calcium is abundantly found in milk, making it a primary dietary source, while vitamin D is often added to milk to enhance its nutritional value. Magnesium is also present, although in smaller amounts compared to calcium. So, the focus on iron deficiency highlights the need for individuals, especially those who rely heavily on milk as a dietary staple, to seek other iron-rich foods to meet their nutritional needs.
