Abstract:
We investigated the efficacy of concurrent use of two of 1alphaOH vitamin D(3), vitamin K(2), and EHDP in increasing lumbar BMD and in preventing new fracture in patients with primary osteoporosis. D(3) + K(2) showed little effect and was considered to be poor combination. EHDP + D(3) or EHDP + K(2) was superior to single use of these agents in both end points.

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...
