Bread Fortified with Cholecalciferol Increases the Serum 25-Hydroxyvitamin D Concentration in Women as Effectively as a Cholecalciferol Supplement

Cholecalciferol significantly increases 25-hydroxyvitamin D concentrations in adults with cystic fibrosis.

BACKGROUND Vitamin D deficiency is increasingly being recognized and treated in patients with cystic fibrosis, although the treatment guidelines are not proven and the effectiveness of vitamin D preparations is untested. OBJECTIVES The aims of this study were to determine the prevalence of 25-hydroxyvitamin D [25(OH)D] deficiency in a large cohort of adults with cystic fibrosis and to evaluat...

Kinetics of serum 25-hydroxyvitamin D in haemodialysis patients treated with monthly oral cholecalciferol

BACKGROUND We previously reported that oral cholecalciferol (CCF) (100 000 IU) taken monthly by haemodialysis patients is effective in accomplishing serum 25-hydroxyvitamin D (25-D) levels >75 nmol/L in >80% of cases. We aimed to study the weekly kinetecs of serum 25-D in HD patients receiving oral CCF during the first 6 months of HD. METHODS All new HD patients at our dialysis centre during ...

Cholecalciferol and 25-hydroxyvitamin D concentrations in adults with cystic fibrosis.

Plasma 25-hydroxyvitamin D in growing kittens is related to dietary intake of cholecalciferol.

Vitamin D synthesis by growing kittens exposed to ultraviolet light is ineffective. Concentration of 25-hydroxyvitamin D (25-OHD) in plasma (the most useful index of vitamin D status) was measured in six groups each of seven kittens given a purified diet (12 g calcium and 8 g phosphorus/kg, calculated metabolizable energy = 20 kJ/g) that contained either 0.0, 3.125, 6.25, 12.5, 18.75 or 25 micr...

Effects of Cholecalciferol vs Calcifediol on Total and Free 25-Hydroxyvitamin D and Parathyroid Hormone.

Context Vitamin D deficiency disproportionately affects nonwhite individuals. Controversy persists over how to best restore low 25D levels, and how to best define vitamin D status [total (protein bound plus free) vs free 25D]. Objective To assess the effects of vitamin D3 (cholecalciferol, or D3) vs 25-hydroxyvitamin D3 (calcifediol, or 25D3) on total and free 25D in a multiethnic cohort of a...
