Which age group has a recommended vitamin D intake of 800-1000 IU daily?

• A. Over 50 years
• B. Under 50 years
• C. All adults 18-65
• D. Children under 12

Answer: (A)

As people age, the need for vitamin D to support bone health increases. Aging reduces the skin’s ability to produce vitamin D, and the body’s efficiency in activating and using it can decline, while many older adults have less sun exposure and a higher risk of osteoporosis. To help maintain adequate calcium absorption and bone strength, guidelines often recommend a higher daily intake of vitamin D for those over 50, around 800–1000 IU per day. Younger adults and children typically have lower recommended amounts, so the 800–1000 IU range is specifically targeted to the older population.
