For moderate supplementation, a standard daily dose of 1,000–2,000 IU (25–50 μg) of vitamin D3 is sufficient to meet the needs of most people. Higher daily doses are in the range of 20–80 IU (0.5–2 μg) per kilogram of body weight. Vitamin D should be taken daily with ...
leading to enhanced bone fragility and consequent increase in fracture risk. Evidence is accumulating for an important role of calcium deficiency as the process of aging is associated with disturbed calcium balance. Vitamin D is the principal factor that maintains calcium homeostasis. Increasing ...
Conversely, histone deacetylation by histone deacetylase enzymes (HDACs) reverses this process to decrease gene transcription. In the absence of vitamin D, corepressors of VDR either have HDAC activity themselves such as protein ALIEN [122], or interact with HDACs such as the nuclear receptor ...

(OH)2D3has been reported to regulate every step of the intestinal transcellular calcium transport process. It induces the expression of the apical membrane calcium channel TRPV6, the calcium-binding protein calbindin-D9k(it has been suggested that calbindin facilitates, in part, translocation of ...
