Actual nutrition, health state and physical working capacity were studied in schoolchildren of three age groups after intake of the polyvitamin "Undevitum" during a month. The results of the investigation conducted have shown that prophylactic measures produced a positive effect on the schoolchildren aged from 11 to 13 and from 14 to 17 years who received 1 degree of "Undevitum" daily. No positive effect was recorded in schoolchildren aged 7-10 years who received 1 degree of "undevitum"/day, every other day.
