How much Vitamin D is recommended for daily intake in adults?

• A. 400 iu - 600 iu per day
• B. 600 iu - 800 iu per day
• C. 800 iu - 1200 iu per day
• D. 1000 iu - 1500 iu per day

Answer: (C)

The recommended daily intake of Vitamin D for adults generally falls into the range of 800 to 1200 IU per day, making this option appropriate for maintaining adequate levels necessary to support bone health and overall wellness. Vitamin D plays a vital role in calcium absorption and bone density regulation, which are critical factors in preventing conditions such as osteoporosis. Older adults, in particular, may require higher amounts due to decreased synthesis of Vitamin D in the skin and potential dietary deficiencies. Research indicates that maintaining Vitamin D levels within this range can help improve bone mineral density and reduce the risk of bone fractures, which is particularly important in the context of bone densitometry assessments. Options that suggest lower intakes, such as 400 to 600 IU or 600 to 800 IU, may not sufficiently meet the needs of many adults, especially those over the age of 70 or individuals with certain health conditions that reduce Vitamin D absorption. Recommendations can vary based on specific factors such as geographic location, skin pigmentation, sun exposure, and individual health status, but aiming for the higher intake range is generally favored for optimal skeletal health.
