Changes of 25-OH-Vitamin D during Overwintering at the German Antarctic Stations Neumayer II and III
Purpose: Humans in Antarctica face different environmental challenges, such as low ultra-violet radiation, which is crucial for vitamin D production in humans. Therefore we assessed changes in 25-OH-vitamin D serum concentration during 13 months of overwintering at the German Stations Neumayer II an...
