Vitamin D is crucial for bone health, immune function, and overall well-being, especially as we age. The Endocrine Society recommends people over 75 to consider taking vitamin D supplements due to increased needs and reduced ability to produce and absorb the vitamin. Older adults have less exposure to sunlight, making it difficult to get enough vitamin D from the sun. Deficiency is common among older adults, with studies showing one in five Australians over 75 are deficient. Vitamin D helps absorb calcium for bone health and may lower the risk of respiratory infections. Routine testing for vitamin D levels is not necessary for healthy individuals over 75, and supplementation is recommended.
