Calcium is a common constituent of multivitamin dietary supplements, [8] but the composition of calcium complexes in supplements may affect its bioavailability which varies by solubility of the salt involved: calcium citrate, malate, and lactate are highly bioavailable, while the oxalate is less.
Speculations on the existence of a possible fifth member of the calcium apatites family, iodoapatite, have been drawn from energetic considerations. [ 41 ] Structural and thermodynamic properties of crystal hexagonal calcium apatites, Ca 10 (PO 4 ) 6 (X) 2 (X= OH, F, Cl, Br), have been investigated using an all-atom Born-Huggins-Mayer potential ...
The U.S. Institute of Medicine (IOM) established Recommended Dietary Allowances (RDAs) for calcium in 1997 and updated those values in 2011. [6] See table. The European Food Safety Authority (EFSA) uses the term Population Reference Intake (PRIs) instead of RDAs and sets slightly different numbers: ages 4–10 800 mg, ages 11–17 1150 mg, ages 18–24 1000 mg, and >25 years 950 mg.

It is the first of its kind to directly measure levels of calcium and magnesium in blood — a much more reliable method of assessing nutrient status. This, the authors hope, might provide clearer ...
Common magnesium-containing minerals are carnallite, magnesite, and dolomite. Common calcium-containing minerals are chalk, limestone, gypsum, and anhydrite. [2] Strontium is the 15th most abundant element in the Earth's crust. The principal minerals are celestite and strontianite. [60] Barium is slightly less common, much of it in the mineral ...
Aragonite is a carbonate mineral and one of the three most common naturally occurring crystal forms of calcium carbonate (Ca CO 3), the others being calcite and vaterite. It is formed by biological and physical processes, including precipitation from marine and freshwater environments. Aragonite crystal structure
Calcium-60 is the heaviest known isotope as of 2020. [1] First observed in 2018 at Riken alongside 59 Ca and seven isotopes of other elements, [26] its existence suggests that there are additional even-N isotopes of calcium up to at least 70 Ca, while 59 Ca is probably the last bound isotope with odd N. [27]
The term calcium phosphate refers to a family of materials and minerals containing calcium ions (Ca 2+) together with inorganic phosphate anions. Some so-called calcium phosphates contain oxide and hydroxide as well. Calcium phosphates are white solids of nutritional value [2] and are found in many living organisms, e.g., bone mineral and tooth ...
