title: [Vitamin C allowance of sailors against a background of qualitatively varied nutrition].
abstract: The authors considered the problem on the issue relative to the requirements of sailors in vitamin C during tropical and arctic sailings. The objects of investigations were routine seagoing-dietary and a trial ration elaborated in conformity with the standard requirements in energy and in basic nutrients. Subject to determination were the vitamin C level in the blood and urine and the resistence of the capillaries. It has been found that within the framework of the trial ration the requirement of sailors for vitamin C comprises 100 mg in the Tropics and 150 mg in the Arctics per man/day.
