What dietary source is high in vitamin A?

Fish oils are recognized as a dietary source that is high in vitamin A, particularly in the form of retinol, which is the active form of vitamin A that the body can directly use. Fatty fish such as salmon, mackerel, and sardines are not only rich in omega-3 fatty acids but also provide significant amounts of vitamin A. This vitamin is crucial for various bodily functions, including vision, immune system performance, and cellular communication.

While milk is a notable source of vitamin A, it mainly provides the vitamin in the form of retinol and is not as high in concentration as fish oils. Leafy greens contain carotenoids, which are precursors to vitamin A, but they do not contain it in its active form. Pasta is generally low in vitamin A and does not serve as a significant dietary source for the vitamin. The high concentration of vitamin A in fish oils makes them the best choice among the options presented.
