Taking an acid blocker(Ppi or H2 blocker) can interfere with B12 absorption. Chronically low B12 has been associated with dementia.
I am on a one x B12 injection for three months. Much easier to remember a jab than when to take a pill! Had the first today.
Not least because in pernicious anaemia oral B12 isn’t absorbed - injections mean it gets where it is needed.
I believe there is a certain kind of nutritional yeast which is high in Vitamin B12. Can be added to recipes or stirred into orange juice.
Unfortunately sometimes we lose the ability to absorb Vitamin B12 so if testing reveals this is the case then it’s injected.
In UK Marmite is pretty good for vitamin B12.
I’ve never met anyone besides myself who likes marmite!
I LOVE Marmite, particularly on crumpets.
I like marmite.
