I recently had bloodwork done for MTHFR and the results showed positive for one copy of the C677T variant and one copy of the A1298C variant. From brief research, I understand that these variants can affect Vit B-12 and folate methylation.

I have been on Jarrow Methyl B-12 5000 mcg: 1x per day – first thing in morning on empty stomach for quite some time.

My B-12 level was 1406 in the standard range of 200-1100 pg/ml. I did not stop taking the vitamin prior to having labs done. Also I started taking Methyl Folate Jarrow 400 mg/1x per day with food.

Any recommendations on testing my B-12. Should I have stopped taking it prior to testing. Also should I have my folate levels checked and if so should I stop taking it prior to testing.
