Starting mtx next month for RA. The 5mg folic acid tabs my rheumy prescribed to mitigate the mtx side-effects only contain folic acid. Shouldn't one take B12 at the same time, because continuous folic acid intake depletes B12? I'm going to take B12 anyway, especially as I'm a vegetarian, but I just found out there's 4 kinds - Methylcobalamin, Cyanocobalamin, Hydroxocobalamin, and Adenosylcobalamin.
Most B12 tabs from pharmacy are methylcobalamin, but the folic acid package insert says to ensure adequate hydroxocobalamin intake. it seems that hydrox.. is converted to methyl... in the body anyway. And cyano... is the synthetic version - will that work? Very confused. Anyone have any advice?
