Calcium works closely with vitamin D to maintain healthy bones, but it also affects the skin. Low calcium levels can sometimes lead to changes in skin pigmentation, including white spots, although this is less common. Similarly, deficiencies in zinc and copper can affect skin pigmentation because these minerals are involved in melanin production, the pigment responsible for skin color. A balanced diet rich in leafy greens, nuts, seeds, and whole grains can help maintain adequate mineral levels.
