title: [The provision of vitamins to school children in rural regions of Lithuania].
abstract: Providing with vitamins of schoolchildren was studied in some regions of Lithuania during the winter-spring period. The biochemical blood count has revealed insufficient providing of schoolchildren with ascorbic acid, beta-carotene, vitamins B1, B2 and B6. Decreased levels of ascorbic acid in urine, as well as micro-symptoms of hypovitaminosis (ascorbic acid, thiamine and riboflavine deficiencies) have been recorded.
