Abstract: | Providing with ascorbic acid, thiamine, riboflavin, vitamin B6 and niacin was studied in miners at deep levels before and after intake of correcting doses of vitamins. Enrichment of the food ration with vitamins produced a positive effect on the working capacity of the miners under study. The levels of vitamin consumption (vitamin-energy coefficients) have been estimated correcting the vitamin balance in miners working at deep levels. |
