[Effectiveness of use in preventive nutrition the food ptoducts with contents of pectin and vitamins].

Daily inclusion in the diet of Pskov GRES workers the drinks or kissels containing 2 g pectin per daily serving (cup) during 6 months was accompanied by a statistically significant decline of their supply with vitamins C, B2, A and beta-carotene. This is reflected both in reducing the average vitamin concentration in blood serum and in the increase of the quota of people with deficiency of several vitamins. Additional inclusion of 13 vitamins in these drinks and kissels, in a dose about 80% of the RDA, has prevented the deterioration of vitamin status.

[Scientific rationale for the use of vitamins in the prophylactic and therapeutic purposes. Report 2. Vitamin deficit as a factor complicating the course disease and reducing the efficiency of medical and prophylaxis measures].

In this connection the treatment of any patient should include a correction of the existing polyvitaminic deficiency and maintain of optimal provision by all micronutrients.

[Effect of vitamin beverages on vitamin sufficiency of the workers of Pskov Hydroelectric Power-Plant].

The research of influence of vitamin complexes in the form of a drink or kissel on vitamin sufficiency of working persons has been carried out. Long inclusion (6,5 months) in a diet of vitamin drinks containing about 80% from recommended daily consumption of vitamins, was accompanied by trustworthy improvement of vitamins C and B6 sufficiency and prevention of seasonal deterioration of beta-carotene status.
