Vitamin B12.
Heard of it?
Okay, so it’s called Cobalamin, but can you tell me what it does?
No? Me neither but it is one of the many things that I shall no longer produce enough of myself since having part of my stomach removed meaning that there will be regular supplements having to be injected on a quarterly basis.
That is along with a daily regimen of multi vitamins, minerals and iron that I shall have to suck down. Not literally iron filings but a manufactured supplement to improve my insides and relieve any borderline anaemia.
