Vitamins are different than other kinds of supplements in that most vitamins are a single
chemical substance, while something like fish oil contains many different chemical substances. Fish oil may come from a single species of fish, but individuals in that species may have differences—like blood donations from many people. Fish oil may also come from a variety of species. This is one of the major hurdles with whole-plant medical cannabis, which contains
hundreds of substances vs. single extracts, as in Sativex or Marinol.
Vitamin D is a group of substances, but
vitamin D3 is just one single substance—cholecalciferol (a.k.a. toxiferol).
It's much easier to control the quality/purity of a single substance than a complex product like a whole plant/herb or fish oil that may come from a multitude of sources.
