Vitamin D and Human Journey

Abstract

Herein, we propose a hypothesis for the low level of vitamin D as a sign of untimely relocation of humans during history. This improper displacement made the human species prone to infectious and noninfectious diseases during the life journey. The low level of vitamin D is a sign that needs to be addressed as a marker of an unsafe journey in lifetime, not the cause for associated diseases, and the replacement of vitamin D is the least performed in this regard.
