Clinical trial of the effect of vitamin B12 in elderly subjects with low serum B12 levels.

A clinical trial of the effect of vitamin B(12) therapy was conducted in 39 elderly subjects who had been found, in a community screening survey, to have low levels of serum B(12) without a macrocytic anaemia or neuropathy. The study produced no evidence which suggests that in such subjects B(12) is superior to placebo in effecting an improvement in psychiatric state or general well-being. There was a clear tendency for all the subjects to show an improvement during the trial, but this probably represents the therapeutic effect of involvement in a research exercise of this kind.
