Olaflur (amine fluoride 297, trade name elmex gel) is a fluoride-containing substance that is an ingredient of toothpastes and solutions for the prevention of dental caries. Especially in combination with dectaflur, it is also used in the form of gels for the treatment of early stages of caries, sensitive teeth, and by dentists for the refluoridation of damaged tooth enamel. Olaflur is a salt consisting of an alkyl ammonium cation and fluoride as the counterion. With a long lipophilic hydrocarbon chain, the cation has surfactant properties. It forms a film layer on the surface of teeth, which facilitates incorporation of fluoride into the enamel. The top layers of the enamel's primary mineral, hydroxylapatite, are converted into the more robust fluorapatite. The fluoridation reaches only a depth of a few nanometres, which has raised doubts whether the mechanism really relies on the formation of fluorapatite.

Magnesium diamide is used as a chemical intermediate. Magnesium diamide is spontaneously combustible. It is toxic by inhalation. Skin or eye contact may cause severe burns.

Calcium lactate is the salt that consists of two lactate anions for each calcium cation (Ca2+); this salt is used as a calcium supplement to treat hypocalcemia. However, as a source of free calcium, this salt is less convenient than calcium citrate. Calcium lactate inhalation powder also called as PUR118 participated in phase I clinical trials to determine whether this formulation was safe and tolerable in a population of subjects with Cystic Fibrosis (CF). PUR118 also was used in another clinical trials to evaluate its effect on ozone-induced airway Inflammation in healthy normal volunteers in case of Chronic Obstructive Pulmonary Disease (COPD). The obtained results revealed that PUR118 reduced the severity of acute exacerbations in COPD and CF and had the beneficial impacts on mortality, morbidity, and quality of life in affected individuals. However, both studies were discontinued.

Magnesium levulinate, the magnesium salt of levulinic acid, is a mineral supplement. It has been shown that in some cases of congenital non-spherocytic haemolytic anaemia (CNSHA) with pyruvate kinase deficiency, the primary defect may be related to diminished magnesium-stimulated ATPase activity, followed by elevation of the erythrocyte ATP level. In CNSHA patients the administration of Magnesium levulinate was followed by an increase in PK activity almost to the control value. This may indicate that magnesium ions stimulate deficient ATPase activity and lead to diminution of ATP as a negative effector for other regulatory enzymes.

Calcium gluceptate (also known as calcium glucoheptonate) was used, as calcium supplements by people who were unable to get enough calcium or who was needed it more. This drug was used to prevent and to treat several conditions, related to the hypocalcemia (not enough calcium in the blood). The body needs calcium to make strong bones; it is also needed for the heart, muscles, and nervous system to work properly. Nevertheless, that use of calcium gluceptate was discontinued.
