Vitamin B12 Shots

Yup.

The pills are a lot cheaper than the shots, so I do the pills.

2x2500 mcg per day the first week.
1x2500 mcg per day after that.

Next trick is to figure out how you got low on B12 in the first place, and address that.
(in my case, it was a malbsorption artifact of celiac disease, now I've been holding steady in the 600's for a few years)
