Recommendations for Vitamin D Intake
New recommendations for vitamin D were released by an expert panel in 2010. These recommendations for daily intake of vitamin D are based on the current literature on vitamin D and are set to protect the health of your bones. They’re based on the assumption that you get no vitamin D from sun exposure.
|Age||RDA or AI*||UL**|
|Birth to 6 months||400 IU***||1000 IU|
|7–12 months||400 IU||1500 IU|
|1–3 years||600 IU||2500 IU|
|4–8 years||600 IU||3000 IU|
|9–70 years||600 IU||4000 IU|
|More than 70 years||800 IU||4000 IU|
*RDA = recommended daily allowance; AI = adequate intake
**UL = upper safe limit for daily intake
***IU = International Units
Some people believe that you may need even more vitamin D than these recommendations; however, the scientific evidence to support these claims is lacking. Still, as long as you stay under the recommended upper safe intake limit, you can choose to take more vitamin D.
