No, B12 is unique. This is because B12 is a huge molecule, and is not very well absorbed without intrinsic factor (which is secreted by the stomach lining). Our dietary requirement RDA is 2-4micrograms a day(a minute amount). There are some other supplements that have some food warnings, acetyl carnitine, alpha lipoic acid, for example.
B12 remains a critical for life nutrient. You will die without it. There is a special carrier for it in the small intestine called transcobalamin which takes it from intrinsic factor into the blood stream and carries it all around the body. Before it was discovered, pernicious anemia, was fairly common and fatal. (lack of intrinsic factor). This is why I doubt sublingual is effective-- no transcobalamin in your mouth.
The vast majority of nutrients can be taken with food. Oils, like Vit E, and Omega-3's do best when taken with food.
