Which vitamin is crucial for the maintenance of bone health in older adults?

Vitamin D plays a pivotal role in maintaining bone health, especially in older adults. This vitamin is essential for the absorption of calcium and phosphorus in the intestines, which are critical minerals for bone formation and maintenance. As individuals age, their skin's ability to synthesize vitamin D from sunlight decreases, and they may also have reduced dietary intake, leading to a higher risk of deficiency. Adequate levels of vitamin D help to prevent conditions such as osteoporosis and fractures, which are significant concerns in the aging population. Therefore, ensuring sufficient vitamin D is vital for preserving bone density and overall skeletal health in older adults.
