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).
Bottom line: Vitamin D intake is recommended at 400â800 IU/day, or 10â20 micrograms. However, some studies suggest that a higher daily intake of 1000â4000 IU (25â100 micrograms) is needed to maintain optimal blood levels.
