Excess Dietary Vitamin A in the Growing Chick: Effect of Fat Source and Vitamin D

Vitamin D: a growing perspective.

Vitamin D deficiency has been widely reported in all age groups in recent years. Rickets has never been eradicated in developed countries, and it most commonly affects children from recent immigrant groups. There is much evidence that current vitamin D guidelines for the neonatal period, 5-10 microg (200-400 IU)/day, prevent rickets at the typical calcium intakes in developed countries. The ann...

The effect of vitamin D supplementation on the size of uterine leiomyoma in women with vitamin D deficiency

Vitamin D and manganese in the nutrition of the chick.

I . In two experiments with chicks given diets of different manganese content, the effects of vitamin D on the Mn contents of bone and liver and on the retention of 54Mn in bone, liver and the whole body were determined. 2. Vitamin D slightly increased the Mn content of dry fat-free bone but the proportion of Mn to ash remained unchanged and the Mn content of bone was influenced much more by th...

The metabolism of vitamin D 3 in the chick.

Physiological doses of radioactive vitamin D3 are administered to vitamin D-deficient chicks 16 hours prior to the preparation of lipid extracts of small intestine, plasma, kidney, and bone. Analysis of the vitamin D metabolite pattern is carried out via column chromatography on silicic acid, Sephadex LH-20, and Celite (liquid-liquid partition), countercurrent distribution and treatment with pe...

Effects of vitamin D supplementation and resistance training on insulin resistance, lipid profile and body fat percentage in T2D men with vitamin D deficiency.
