Vitamin D Status of Submariners during Patrol

Abstract

The circulating vitamin D (25-OH-D) levels were measured in 22 submariners before, during and after a three month patrol. Eleven subjects received a multivitamin-mineral supplement that contained 10.0 mg of ergocalciferol while the other 11 received a placebo. Vitamin D levels decreased during the patrol for both groups, but the decline was significant only for the placebo group. Post patrol blood levels were higher than prepatrol levels due to the change in season and the higher levels of ultraviolet radiation in the environment. Keywords: Ergocalciferol; Vitamin supplement.
