Morphology

vitamin + B + complex

The meaning 'a group/combination of B vitamins' is directly and compositionally derivable from 'vitamin' (a nutrient) + 'B' (the B vitamin group) + 'complex' (a combination or set). This noun phrase follows transparent compounding patterns found across languages, so a B1 learner who knows the constituent words will very likely infer the intended meaning.

Etymology

Vitamin B complex comes from an old idea that all the B vitamins were one single vitamin called vitamin B, so people spoke of a complex, meaning a 'group' of related vitamins. That's why vitamin B complex today means the set of several B vitamins taken together.
