Vitamin D is different from most other vitamins. When the body processes it, vitamin D becomes a hormone called calcitriol, which makes bones in the body absorb calcium. Vitamin D is a nutrient that is important for health. Certain foods contain a small amount, but people can make most of the vitamin D that they need from sunlight.

The recommended dietary intake is in IU, which is International Units. The Food and Nutrition Board (FNB) recommend and Trusted Source the following intake per day to maintain a healthy level of vitamin D:
Age – Recommended daily intake of vitamin D
0 to 12 months 400 IU
1 to 70 years 600 IU
70 years and above 800 IU
For adults with vitamin D levels below 30 ng/mL, the Endocrine Society guidelines recommend a daily intake of 1,500–2,000 IU to restore healthy levels of vitamin D. There are also treatment options where people with vitamin D deficiency receive 50,000 IU weekly or monthly instead of taking a daily dose.
