Abstract or Summary
  • Plasma vitamin B₁₂ concentrations of 16 elderly women were measured using the growth response of the microorganism, Ochromonas malhamensis. The method required major modifications which are described in detail. All women had plasma concentrations of vitamin B₁₂ above the normal minimum of 200 pg/ml despite the fact that the diets of nine women failed to meet the RDA of 3 μg/day. The mean dietary B₁₂ of 11 women who took no supplemental B₁₂ was 2.90 μg/day; their mean plasma concentration was 415 pg/ml. The group of five women who took B₁₂ preparations had an average total intake of 13.89 μg/day and a significantly higher plasma concentration (628 pg/ml). Supplemental intakes of ascorbic acid in the range of 200-1100 mg/day had no destructive effect on vitamin B₁₂ in plasma.
