[The effect of preventive vitamin supplementation on vitamin status and work productivity of conveyer belt workers in light industry].

The authors have studied the ways of correcting the vitamin status and influence of vitaminization on working capacity in workwomen in light industry. Prophylactic polyvitaminization (1 dragee of "Undevitum"/day, during 2 months) proved to produce positive effect on the vitamin status parameters (vitamin content in the blood and urine, clinical microsymptoms of vitamin deficiency), and on the dynamics of the physiological parameters of working capacity of workwomen at modern conveyer shoe making industry. It is recommended that persons suffering from chronic diseases influencing vitamin metabolism, first of all those over 45 years, should receive increased doses of prophylactic polyvitamins, thiamine and ascorbic acid, in particular.
