When an individual lacks an adequate amount of vitamin D in the body, he/she is said to be facing a deficiency. Vitamin D presence is measured in nanograms per millilitre or ng/mL. Usually, vitamin D levels between 20 and 50 ng/mL are considered the normal levels. Thus, deficiency would be when a person shows vitamin D levels below this range.
