Purpose Of Review:
New evidence for recommendations for vitamin D supplementation in healthy infants based upon recent literature.
Recent Findings:
Randomized controlled trials published since 2009 that related to vitamin D doses in infancy were reviewed. They do not provide any additional evidence that larger, more generous amounts of daily vitamin D beyond the customary recommended 400 IU daily dose, affect any significant outcome. Larger amounts may lead to serum 25 hydroxy vitamin D concentrations that have been reported to be potentially associated with adverse effects.
Summary:
There are still many unanswered questions left, in particular whether or not more 'generous' amounts of vitamin D in infancy may improve long-term health outcomes such as prevention of osteoporosis, allergies, or cancer.

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).
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...
