Vitamin D can be produced by the body when the skin is exposed to sunlight (specifically UVB rays), while Vitamins A, B12, and C are generally obtained from dietary sources as the body can't produce them on its own (or in sufficient amounts for Vitamin A from precursor carotenoids, but the primary production of Vitamin D is endogenous via sun exposure).
