Vitamin D level in tropical indigenous populations

As an anthropologist I’ve often wondered just what level of vitamin D would be found among indigenous populations living traditional lifestyles. A new study provides insights on the natural vitamin D levels of tropical indigenous individuals. And the good news is that the vitamin D level found among these native populations is very similar to what I have held as the “optimum” vitamin D level.
