I'm about to start a B12 supplement (the Jarrow 1000mcg lozenges; they were cheaper on Amazon than the 500mcg lozenges); I already take a B complex tablet in the morning (Boots standard one) so nothing should be unbalanced. My question is this: my last B12 reading was 500-odd (range 190-900), so not terrible but not wonderful either so should I take 1000mcg every day, or every other day? I know you can't overdose on B12 but don't want to waste it either.
Additionally, my last folate reading was 8-odd, can't remember the reference range. What impact is the B12 supplementation likely to have on my folate level?
