What is the recommended vitamin D intake?

• A. 400-600 IU/day.
• B. 800-1000 IU/day.
• C. 2000 IU/day.
• D. 120 IU/day.

Answer: (B)

Vitamin D is essential for calcium absorption and bone mineralization, which is especially important for postmenopausal women at risk for osteoporosis. For most adults, including those with limited sun exposure, a daily intake of about 800 to 1000 international units provides enough vitamin D to support bone health and maintain adequate vitamin D status. Lower amounts, like 400–600 IU/day, are often not sufficient for many adults, particularly older individuals. Higher amounts such as 2000 IU/day are sometimes used for deficiency treatment in specific situations but aren’t the routine recommendation for all adults, while 120 IU/day is clearly too low to support bone health. So, the standard recommended intake is around 800–1000 IU daily.
