The recommended daily intake of vitamin D varies depending on age, sex, and other factors. The following are the current recommended daily intakes of vitamin D, as per the Institute of Medicine:
- Infants up to 12 months: 400-1,000 IU/day
- Children 1-18 years: 600-1,000 IU/day
- Adults 19-70 years: 600-1,000 IU/day
- Adults 71 years and older: 800-1,000 IU/day
However, some experts suggest that higher amounts of vitamin D may be needed for optimal health, particularly for individuals who are at risk of deficiency. Some studies suggest that a daily intake of 1,000-4,000 IU/day may be needed to maintain optimal blood levels of vitamin D.
It's important to note that excessive intake of vitamin D can be harmful, leading to toxicity and a range of health problems. Therefore, it's always best to consult with a healthcare provider before starting any new supplement regimen, particularly if you have any underlying health conditions or are taking medications that may interact with vitamin D.
