Hi, I don't know if this thread is still active but it seemed the appropriate place to post this...

Does anyone know if taking B12 increases your folate as well?

I tried taking methylB12 for a few months which significantly boosted my B12 serum levels (started out low end of 'normal' range), although made no change to my PN symptoms (was worth a try). I was surprised to see that my folate levels had doubled and were no longer low despite not taking any folate supplements.

Also, before taking any B12 I had my local doc order a MMA and homocysteine blood test. My MMA was normal but my homocysteine was a little high. Doc had no idea what that meant so it didn't get followed up at all. My super googling skills tell me it can sometimes indicate a deficiency in B12, folate or B6... What kind of specialists knows about these things and can interpret this for me? I'm seeing a rheumatologist, neurologist and dietitian over the next few months.

Cheers
