Evolution of the Calcium Paradigm: The Relation between Vitamin D, Serum Calcium and Calcium Absorption
Osteoporosis is the index disease for calcium deficiency, just as rickets/osteomalacia is the index disease for vitamin D deficiency, but there is considerable overlap between them. The common explanation for this overlap is that hypovitaminosis D causes malabsorption of calcium which then causes secondary hyperparathyroidism and is effectively the same thing as calcium deficiency. This paradig...
متن کاملMineral Absorption & Deficiency
A wide range of minerals is essential for human health. The recommended dietary allowances (RDAs) serve as guidelines for daily intakes of nutrients that population groups in the United States should have in their diets. Dietary Reference Intakes (DRIs) have been established for the following essential minerals: calcium, phosphorus, and magnesium. In addition, DRIs have been set for other trace...
متن کاملEffects of hydrated sodium calcium aluminosilicate on fescue toxicosis and mineral absorption.
The possibility of supplementing livestock diets with an aluminosilicate to protect them from fescue toxicosis was investigated. An in vitro study showed that hydrated sodium calcium aluminosilicate (HSCAS) removed greater than 90% of the ergotamine from aqueous solutions at pH 7.8 or lower, indicating a high affinity of ergotamine for HSCAS in vitro. Rats fed diets containing tall fescue seed ...
متن کامل[Intestinal absorption of calcium gluconate and oseine-mineral complex: an evaluation by conventional analyses].
Calcium (Ca) preparations are widely used in the treatment of osteoporosis, usually as soluble salts. Tolerance might be improved by prescription of slowly dissolved Ca preparations, since Ca is also absorbed distally, even in the colon. In this regard the use of natural forms of Ca might be advantageous, but natural products cannot be labeled reliably for easy evaluation of their absorption. T...
متن کاملCalcium absorption across epithelia.
Ca(2+) is an essential ion in all organisms, where it plays a crucial role in processes ranging from the formation and maintenance of the skeleton to the temporal and spatial regulation of neuronal function. The Ca(2+) balance is maintained by the concerted action of three organ systems, including the gastrointestinal tract, bone, and kidney. An adult ingests on average 1 g Ca(2+) daily from wh...
