Effect on Rats of Purified Diets with Synthetic B Vitamins

Nature volume 158, pages 792793 (30 November 1946) | Download Citation



DURING the early years of the War, we investigated the possibility of providing the factors of the vitamin B complex in growing rats by giving them these factors exclusively in the form of the following synthetic components : thiamine, riboflavin, pyridoxine, niacin, pantothenic acid and choline. Most of our unpublished results have been confirmed by other investigators, and may be found in the Anglo-American literature of 1940–45. Some of our experiments, however, are in essential details different from those already reported.
