Its only known side effect is that it may work as a laxative in high concentrations. [14] Magnesium carbonate is used in taxidermy for whitening skulls. It can be mixed with hydrogen peroxide to create a paste, which is spread on the skull to give it a white finish. Magnesium carbonate is used as a matte white coating for projection screens. [15]
Magnesium is absorbed orally at about 30% bioavailability from any water soluble salt, such as magnesium chloride or magnesium citrate. The citrate is the least expensive soluble (high bioavailability) oral magnesium salt available in supplements, with 100 mg and 200 mg magnesium typically contained per capsule, tablet or 50 mg/mL in solution.
The structures of solid magnesium citrates have been characterized by X-ray crystallography.In the 1:1 salt, only one carboxylate of citrate is deprotonated. It has the formula Mg(H 2 C 6 H 5 O 7) 2 The other form of magnesium citrate has the formula Mg(HC 6 H 5 O 7)(H 2 O) 2, consisting of the citrate dianion (both carboxylic acids are deprotonated). [1]
Magnesium aspartate is a compound formed by the combination of the divalent magnesium cation (Mg2+) and the dicarboxylic amino acid aspartate (C4H6NO4-). [1] The chemical formula for this compound is Mg(C4H6NO4)2. [7] The structure of magnesium aspartate consists of a central magnesium ion that is chelated, or bound, by two aspartate anions.
10% calcium gluconate solution (given intravenously) is the form of calcium most widely used in the treatment of low blood calcium.This form of calcium is not as well absorbed as calcium lactate, [12] and it only contains 0.93% (93 mg/dL) calcium ion (defined by 1 g weight solute in 100 mL of solution to make 1% solution w/v).
Common side effects include low blood pressure, skin flushing, and low blood calcium. [1] Other side effects may include vomiting, muscle weakness, and decreased breathing. [4] While there is evidence that use during pregnancy may harm the baby, the benefits in certain conditions are greater than the risks. [5]
Anhydrous magnesium acetate has the chemical formula Mg(C 2 H 3 O 2) 2 and in its hydrated form, magnesium acetate tetrahydrate, it has the chemical formula Mg(CH 3 COO) 2 • 4H 2 O. In this compound magnesium has an oxidation state of 2 +. Magnesium acetate is the magnesium salt of acetic acid. [1]
Calcium lactate has similar absorption as calcium carbonate, [42] but is more expensive. [41] [26] Unlike calcium carbonate, calcium lactate can be absorbed at various pHs, thus it does not need to be taken with food. [26] Calcium lactate is a less concentrated forms of calcium than calcium carbonate. [41] Calcium lactate contains 13% elemental ...
