This is a composition of the noun 'vitamin' with a specific label 'B12', so a learner who knows 'vitamin' and understands alphanumeric labeling will recognize it as a particular kind of vitamin. While they might not infer the detailed medical uses, the basic referential meaning (a specific vitamin) is directly derivable and this naming pattern is common across many languages.
Etymology
Vitamin B12 came when scientists put it in the 'B' group of vitamins and found it contained a metal called cobalt that can make it look reddish. That's why vitamin B12 is the name for the nutrient known for helping make red blood cells and keeping the nervous system healthy.
