What is the RDA for vitamin D for adults aged 51 to 70 years?

Explanation:
The amount needed daily to support bone health and calcium metabolism in adults aged 51–70 is 10 micrograms per day. This level provides enough vitamin D to enhance calcium absorption from the gut, help maintain bone mineralization, and reduce risk of bone-related issues as people age. Ten micrograms also translates to 400 International Units, a commonly cited daily amount that balances typical sun exposure and dietary intake for most healthy adults in this age range. While some guidelines describe higher intakes for people with limited sun exposure or higher risk factors, this value represents the standard recommendation often used for adults 51–70.
