I am 24 and pure vegetarian. My
B12(Cyanocobalamin-CoCbl) result was 197 and also feeling some fatigue with normal KFT.
I am advised by Doctor to take
Methylcobalamin 1500 mg 1 Tab daily
repeat the same test after taking it for 4 weeks.
But I got and taking a better option(As per 2015 K Thakkar, G Billa EJCN paper, don't know reality 😕🙁)
Adenosylcobalamin(AdCbl) 750mg
Methylcobalamin(MeCbl) 750mg with Folic Acid.
But I don't get that how taking AdCbl/MeCbl will affect the concentration of CoCbl in the blood.
Is there any conversion between these forms?
OR, Methylmalonic acid (MMA), TCII (transcobalamin) is a better test to detect B12 active forms deficiency ?
