Since you have relisted the question, and DoogleNK is offline I can try to help you. For people with B12 deficiency we usually recommend 1,000 mcg of oral replacement per day. This is available at any pharmacy or mass retailer and is very inexpensive. Dozens of studies have shown that injections don't work any better than the pills. The normal B12 level is 200 - 900 pg/ml, so you are a bit low.
