Figure 1. Spectrum of Vitamin D Status.

Figure 1

The spectrum of low vitamin D status is depicted. At very low vitamin D levels, (25[OH]D of approximately 10 ng/ml or below) calcium malabsorption, osteomalacia/rickets and myopathy occur. Less marked vitamin D deficiency (often referred to as inadequacy or insufficiency) has been associated with a variety of adverse health consequences. Consensus regarding an “optimal” 25(OH)D concentration continues to evolve, however there appears to be increasing agreement that values above approximately 30-32 ng/ml are associated with optimal physiologic function.
