Vitamin Requirements in Industry

When the available supply of foodstuffs cannot be depended upon to satisfy even average requirements for specified food factors, then food concentrates or synthetic vitamins may be the only immediate answer. Such conditions can arise under unusual occupational conditions, as well as from economic, supply, storage, or culinary reasons. Every effort must be made to supply adequate meals or foods or to correct the carried lunches or to do whatever else can be done, rather than to rely solely upon distribution of multiple-vitamin preparations. 

It is not possible to assure industrial workers or anyone else that they can maintain optimal nutritional health just by swallowing vitamin or vitamin-mineral pills daily, and continuing to eat poorly balanced meals. 

The amount of a vitamin required by a human being varies from moment to moment, according to diet, activity, health, response to stress, dynamic equilibria in the body, etc. The amount also varies from one individual to another according to body size, activity, sex, age, drugs, diet, etc.
