sometimes accents are stupid and pronunciations Do Not Generalize
an example of this is vitamin. where i am in america it's pronounced with an "eye" i, so the vi rhymes with "bye." Where I was in the UK it's pronounced with an "ih" I, so the vi is like the vi in "Victoria."
so now if it's taking about the concept of vitamins as a category, i use the US pronunciation. if i'm talking about specific ones, like vitamin c, i use the UK pronunciation.
(usually. if i remember i might swap wildly between the two as i try in vain to remember which pronunciation is correct for the country i'm in)
don't even get me started on the way i use the UK pronunciation of "garage" for everything except for garage sales
