James - this is not going to be much help but I am still taking the Methylcobalamin but no shots. I have not been re-tested. My health is improving as of late, and with a different doc, from working on my thyroid though.

Eck, this is an old thread. What happened with your B12 Senneth? I'm also curious if you were taking Cobalamin (common source) vs Methylcobalamin. The Methylcobalamin is the variant that your body uses, and it may or may not be converting Cobalamin to it very well.

Ah. I should mention that I have super bad food allergies, a leaky gut, autoimmune and absorption problems. So I think my doc is trying to overcompensate since I can't absorb much in any case. Also Dr.K isn't my cup of tea, so I won't be asking him.

Were you encountering any symptoms (tingly limbs, brain fog, etc), or are you just taking his word for it that it's not "optimal" (whatever that means)? They're fucking with you IMO. Twice weekly B12 shots? Are they making money off that shit? If so, I would really re-consider. I mean, I would reconsider either way. Maybe get a second opinion? Perhaps ask Dr. K whether 366pg/ml calls for getting B12 shot into you WHILE supplementing with pills? Be careful!

Is the B12 test part of a normal matabolic profile blood test, or does it require a specific panel?

I had a B12 test last month. I was at 366pg/ml. Healthy Range was 200-1100pg/ml. My doc says I am 'not optimal' and that she likes to see it at between 700-800pg/ml. So now I am taking a supplement (1000mcg/daily) and twice weekly B12 shots. I must be missing the best sources or not digesting/absorbing it correctly.

The serum B12 lab ranges in most countries are very low similarly to Vitamin D. Most labs have somewhere around 200-1100pg/ml as a normal range. However, it is considered that the low range of that signifies sub-clinical B12 deficiency. That is why Japan have >500 pg/ml range and any levels below that are treated.

For more info check the book Could it be B12?
