VITAMIN D: WHAT HAPPENS WHEN YOUR BODY DOES NOT HAVE ENOUGH OF IT?

Vitamin D Deficiency

There is no official set level of vitamin D deficiency. To measure the amount of vitamin D in the blood, scientists use nanograms per millimeter (ng/mL). Some consider that if the blood has less than 12 ng/mL of vitamin D the body is deficient and if the amount is less than 20 ng/mL then it is a red alert.

Another group believes that the amount should be higher and alarm bells should ring in case it is less than 30 ng/mL.
