On march 17 2010 my Vitamin b-12 level was 162 pg/ml. I started taking ** Methyl B-12 1000mcg a week or so later. I experimented and gradually worked up to taking four ** Methyl B-12 5000mcg pills each day. I took them sublingually.

On the April 7th 2010 i had another blood test and my level was 5297 pg/ml. I stopped taking the 5000mcg b-12. Since then i have only taken a B group multivitamin containing 1000mcg of b-12. These have been taken orally.

My last blood test for b-12 was on June 2nd 2010. Result was 649pg/ml.

I felt good while taking the high dose and had no ill effects. I only stopped because the doctor said I should.

After reading some of the posts on this website I am going to experiment with a higher dose, and try to maintain a higher level.

I am having another blood test tomorrow 23.11.2010.
