That MCV is not alarming.
It would be optimal to take your 1000mcg B12 on an empty stomach. Oral use has been tested and found to work in patients with pernicious anemia.
It is also a good idea to use the activated form of B12 called methylcobalamin. Cyano is synthetic and not active and has to go thru 4 chemical steps to become useful in the body.
10 to 30% of people in the US have a genetic error that blocks the activation (methylation) of B12 and folic acid. So taking B12 in methyl form by passes this error. This is very inexpensive...pennies a day.
If you have headache that appears to be migraine, you can also try to improve your magnesium status. Sometimes this fixes headaches. About 70% of people in US are low in magnesium.
Choose a supplement that is NOT oxide form since oxide is not absorbed.
This is my magnesium thread:
Aim for 200mg elemental daily to start. This is about 1/2 the RDA for magnesium for adults. The thread explains elemental, and also gives food choices if you wish to do it that way instead.
