1 doctor agrees

In brief: Vtiamin OD

I would get blood work done in an annual pyhsical and ask your dr to do a serum B12 level.
If it is adequte you do not need b12 there is a lot of conflicting information on multivitamins. I am not sure what you mean by :"high doses" but I am sure if you follow the directions on the label of any multi you will be fine.
