Hi everyone. Over the last few months I’ve put a few posts on here about my concerns about having low B12. My test results are as follows:
Serum B12: 182 ng/l (180-1000) and a few weeks later 202 ng/l
Homocysteine: 9.9 mmol/l
MMA: 0.25 umol/l
Serum folate: 5ug/l
Vitamin D: 44.5 nmol/L (it had dropped to 34.5, but have been now taking 6,000IU a day, so I think it’s increasing)
Anti-Intrinsic factor: Negative
I have bought some Jarrows 5,000mcg B12 Methylcobalamin and a good quality whole-food multi supplement. Before I start taking these I was considering having the active b12 test to see what it was, since once I start taking the B12 I know that this result will not be a reliable indicator due to the supplements. However, the active test needs a GP referral, and while my GP did order the additional tests I asked for, he has now adamantly told me that I do not have B12 problems, so won’t give me the referral.
So my question is, should I forget about having the test and just start taking the supplements, or investigate the much more expensive Blue Horizon active b12 test? I’ve been waiting a while for the results of my MMA test, and so have been putting off taking the B12/supplements. I don’t want to keep waiting though as things won’t improve (well let’s hope so anyway) until I do start taking the B12/supplements.
So what's your thoughts?
