The Health Benefits of Vitamin D

How much do you need?

The amount of vitamin D needed for healthy functioning has been a source of debate. According to new research, you need more vitamin D than previously thought.

The normal range for blood serum levels is 50 to 100 micrograms per deciliter. You can require more vitamin D depending on your blood level.

New guidelines based on international units (IUs) per day have been released by the Institute of Food and Agricultural Sciences.

Drugs and vitamins are measured in IUs, which is a common unit of measurement. IUs aid experts in determining the appropriate dosage, toxicity, and deficiency levels for each person.

Each form of the vitamin has a different IU value. The amount of a material that causes an impact in your body is measured in IUs. The IUs for vitamin D are as follows:

children and teens: 600 IU
adults up to age 70: 600 IU
adults over age 70: 800 IU
pregnant or breastfeeding women: 600 IU
