Vitamin C Status of Submariners
Abstract
Plasma vitamin C levels were determined for 28 submariners prior to, during, and after a 68-day patrol. A significant reduction occurred in plasma vitamin C levels during the patrol compared to levels obtained before and after the patrol. These reductions were unrelated to health and performance effects as determined by total dispensary visits, frequency of upper respiratory infections, and training accomplishments. Smokers had significantly lower levels of plasma vitamin C than non-smokers, as did those who had made several previous patrols. Vitamin supplements did not appear to ameliorate the vitamin C deficiency found among smokers, but did enhance the plasma levels of vitamin C among non-smokers. These findings indicate that dietary or supplemental intake of vitamin C among submariners should be increased, especially among those who smoke or who have made several patrols.
