Abstract:
We review the potential of vitamin D for the prevention of falls and fractures. Evidence from randomized-controlled trials will be reviewed for both endpoints, as well as epidemiologic data that correlates higher 25-hydroxyvitamin D status with better bone and muscle health. This review summarizes the compelling dual benefit of vitamin D on bone and muscle health, a concept that is unique and important for optimal fracture prevention at higher age. We will review sources of vitamin D and calcium and also outline why calcium supplementation alone may not contribute to fracture prevention at higher age. This review concludes that vitamin D at a dose of at least 800 IU per day should be provided to all postmenopausal women and everybody starting at age 60 for optimal bone and muscle health. In combination with a vitamin D supplement, dairy products may be an optimal source of calcium at higher age as milk provides both calcium and protein.

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
