The Vitamine Manual

The manual surveys the discovery and early chemical investigation of vitamins, reviewing experimental approaches used to isolate and identify them. It describes laboratory methods for testing vitamin presence and activity, including yeast-based assays for the B complex, and provides standardized basal diets and recipes used in feeding trials. Sources, chemical and physiological properties of different vitamins are summarized, with guidance on incorporating them into diets and interpreting deficiency syndromes. Technical tables, salt mixtures, and a bibliography are included to support students and investigators conducting nutritional research.
