A common dietary source of vitamin D aside from sunlight is fatty fish, such as salmon, mackerel, and sardines. These fish are rich in vitamin D, essential for bone health and immune function. Other sources include fortified foods like milk, orange juice, and cereals, as well as egg yolks. Supplementation may also be considered, particularly for individuals with limited sun exposure. Adequate vitamin D levels are crucial for overall health, supporting calcium absorption and promoting skeletal health. Ensuring a balanced intake from various sources contributes to optimal health outcomes.
