Why is vitamin D important for older adults?

• A. It prevents hair loss
• B. It supports immune function and bone health
• C. It improves skin elasticity
• D. It helps in digestion

Answer: (B)

Vitamin D is crucial for older adults primarily because it plays a significant role in supporting immune function and maintaining bone health. As individuals age, they often experience a decrease in bone density, making them more susceptible to fractures and osteoporosis. Vitamin D promotes calcium absorption in the gut, which is vital for the formation and maintenance of strong bones. Additionally, vitamin D is known to be important for the immune system, helping to enhance the body’s defenses against infections and diseases. Older adults often have a weakened immune response, making this vitamin essential for their overall health and well-being. While other options mention issues like hair loss, skin elasticity, and digestion, these are not the primary functions or benefits attributed to vitamin D in older adults. Thus, the correct choice underscores the vitamin's vital role in two critical areas: the immune system and bone health.
