However, PTH can change due to renal function, exercise level, the time of day, or even diet. There has been no consensus on the optimal level of vitamin D intake to reduce PTH, and this is why many laboratories report the normal range of vitamin D to be so wide (20 to 40 ng/ml, or in some cases, 50 to 100 nmol).
Vitamin D is produced when sunlight converts cholesterol on the skin into calciol (vitamin D3). Vitamin D3 is then converted into calcidiol (25-hydroxyvitamin D3) in the liver. The kidneys then convert calcidiol into the active form of vitamin D, called calcitriol (1,25-hydroxyvitamin D3).ne microgram of vitamin D is equal to 40 IU of vitamin D. The recommended intakes of vitamin D throughout life were updated by the US Institutes of Medicine (IOM) in 2010 and are currently set at: 1  Infants 0-12 months - 400 IU (10 mcg). 2  Children 1-18 years - 600 IU (15 mcg).
