Nutritional impact of elevated calcium transport activity …
Nutrition recommendations worldwide emphasize ingestion of plant-based diets rather than diets that rely primarily on animal products. However, this plant-based diet could limit the intake of essential nutrients such as calcium. Osteoporosis is one of the world''s most prevalent nutritional disorders, and inadequate dietary calcium is a known contributor to the pathophysiology of this condition

Calcium bromide - Wikipedia
Calcium bromide is the name for compounds with the chemical formula CaBr2(H2O)x. Individual compounds include the anhydrous material (x = 0), the hexahydrate (x = 6), and the rare dihydrate (x = 2). All are white powders that dissolve in water, and from these solutions crystallizes the hexahydrate. The hydrated form is mainly used in some

The expected pK a s of metal-bound water for calcium and strontium are 12.7 and 13.2 (see refs. 22 , 25 , 26 , and references therein). The observed shift when strontium-YZ (1,507 cm −1 ) is compared with calcium-YZ (1,503 cm −1 ) is consistent with a change in hydrogen bonding between the YZ phenoxyl oxygen and calcium/strontium-bound water.

This is done by using a calcium salt with a low solubility (such as calcium citrate) which slowly releases calcium ions. An alternate method is to use a calcium salt which is practically insoluble in neutral solution but dissolves as the pH falls (such as dicalcium phosphate); when an acid of low solubility (such as adipic acid) is added, it gradually lowers the pH, calcium ions are released
