Vitamin D Deficiency, Low Bone Density
Nursing-Home Residents Given Bread Fortified With Vitamin D3
Background. For older adults, serum 25-hydroxyvitamin D (25(OH)D) higher than 75 nmol/L lowers fracture risk and attainment of this 25(OH)D target may require 125 mcg (5000 IU)/d of vitamin D3.

- NCT00789503
- Testing
- Bread fortified with vitamin D3 and calcium

Vitamin D Deficiency, Secondary Hyperparathyroidism
Vitamin D Status in Males in Jerusalem Area and Its Correlation to Parathyroid Hormone (PTH) Level and Bone Mineral Density
Because of its high sun exposure, Israel was traditionally supposed to be protected from vitamin D deficiency, and the country food products hardly contain vitamin D supplements.

Hypophosphatemia
Observing the Changes of Fibroblast Growth Factor 23 in Patients of Tumor Induced Osteomalacia
Fibroblast froth factors (FGFs) are humoral factors identified by their ability to stimulate cell proliferation1. They play different roles in the regulation of cell proliferation, differentiation and function.
