What is the Vitamin D requirement for individuals aged 1 year to 70 years?

The recommended vitamin D requirement for individuals aged 1 year to 70 years is 600 International Units (IUs) per day. This guideline is based on the importance of vitamin D for maintaining bone health and supporting the immune system. Adequate levels of vitamin D help in calcium absorption, which is essential for developing and maintaining strong bones. The recommended intake is designed to ensure that individuals receive sufficient vitamin D to maximize these health benefits while minimizing the risk of deficiency-related conditions, such as rickets in children and osteoporosis in adults.

As individuals within this age range typically have access to sunlight, some absorption of vitamin D occurs through skin synthesis; however, dietary sources and fortified foods also play a crucial role in meeting the required intake. Adjustments to these recommendations may be made based on specific health circumstances, dietary habits, and geographical location, but 600 IUs is established as the standard daily intake for this age group.
