Even though it seems easy enough to get, according to recent data published in the European Journal of Clinical Nutrition, vitamin D deficiency is prevalent in 24% of Americans, 37% of Canadians and 40% of Europeans [1]. Data from 2012 indicate that 50% of the world’s population are vitamin D insufficient. A deeper look reveals that vitamin D deficiency and insufficiency vary by age, sex, ethnicity and geographic location, with reduced time spent outdoors and insufficient consumption of vitamin D-rich foods having the greatest impact on suboptimal levels [2].
