can b12 boost metabolism. i've just started taking 1000 mcg of vitamin b-12 sublingual tablets. i'm hoping they will boost my metabolism. i'm 67 and eating maximum 1200 calories a day (dieting). regular exercise is almost impossible due to back pain etc. does anyone know if the above dosage of b-12 might boost metabolism or am i wasting money and hoping for results that are not likely.
