What is the RDA for vitamin D for adults 70 years and older?

Explanation:
Older adults need more vitamin D to support calcium absorption and bone health because skin production declines with age and sun exposure can be limited, increasing the risk of deficiency. The recommended daily allowance for adults 70 years and older is 20 micrograms per day (800 IU). This amount helps maintain adequate vitamin D status to protect bone health, whereas lower intakes (such as 5, 10, or 15 micrograms) are generally not sufficient for this age group.
