I am deficient in B12 as well as folate + iron, according to latest bog-standard NHS blood tests.
Been paranoid about supplementing (cyanocobalamin tabs 25mcg) more frequently than every few days/weeks or so due to concern about aforementioned 'methylation' issue.
Doc (GP) suggests Schilling test (didnt go, cos no point; WE know whats causing it!)
But worried about getting injections, if they trigger really bad seizures, then have to go home alone, potential nightmare lol
Interested in sublingual, gradual experimental dosing though.

may i ask where u get this methylcobalamin supplement?

Thanks
