The forms of vitamin B12 in foods

  • J. Farquharson (a1) and J. F. Adams (a1)
Abstract

1. The forms of vitamin B12 were determined in foods, most of which had been prepared for consumption.

2. Five forms were detected: adenosylcobalamin, hydroxocobalamin, methylcobalamin, cyanocobalamin and sulphitocobalamin. Adenosylcobalamin and hydroxocobalamin were the predominant forms.

3. The intestinal absorption of [57Co] sulphitocobalamin was estimated and found to be lower than that of [58Co]cyanocobalamin.
