The water-soluble B-vitamins

Abstract

The growth responses to lactoflavin of rats receiving as source of other factors of the vitamin B complex vitamin B1 and fuller''s earth filtrate from autoclaved yeast extract or vitamin B1 and an alcoholic extract of wheat germ, showed fair proportionality to the dosage of lactoflavin. Maximum growth of approximately 18g. weekly was obtained only when the rats received 40[gamma] of lactoflavin daily. Similar growth responses were obtained using the yeast fuller''s filtrate and the alcohol extract of wheat germ.
