I have been reading up on vitamins and wasn't aware that the vitamins that most people purchase are synthetic vitamins derived from other things and therefore are pretty much useless. I keep hearing about supplementing with K2 or supplementing with D3. Do you think they mean supplementing with synthetic vitamins or supplementing with whole food vitamin complexes which contain the entire vitamin complex? Apparently the vitamin is nothing without it's complex.

Many vitamins are not a single molecule, but a number of related molecules that have similar function. B12 is a good example, you can have methyl-B12, cyano-B12, hydroxy-B12, or adenosyl-B12. They all get converted to active B12 in the body, you don't need all of them or even a mixture of them. K2 is a family of menaquinones, varying by the isoprene tail. MK-4 is the useful from in humans, though MK-7 (found in natto) has some activity as well.
Vitamin D as supplemented is a provitamin, not the active form, but an intermediate that gets converted to the active vitamer in the body. Beta carotene is the provitamin form of vitamin A.
Synthetic vitamins are indeed vitamins and biologically active. Vitamins do have relationships with each other and other nutrients so it is true that a vitamin in isolation may not necessarily be useful (but it most often is.)
