Potash (Dihydroxyaluminum Sodium Carbonate), a component of Kompensan-S Forte in Germany, is a basic inorganic salt that acts by neutralizing hydrochloric acid in gastric secretions. Kompensan-S Forte is slowly solubilized in the stomach and reacts with hydrochloric acid to form aluminum chloride and water. It also inhibits the action of pepsin by increasing the pH and via adsorption. Cytoprotective effects may occur through increases in bicarbonate ion (HCO3-) and prostaglandins.

Anhydrous dibasic calcium phosphate is a calcium salt of phosphoric acid. It is used as a diluent in pharmaceutical industry, in some toothpastes as a polishing agent. Calcium phosphate is generally recognized as safe by FDA. Dibasic calcium phosphate is ised as a supplement to treat conditions associated with calcium deficit, such as bone loss (osteoporosis), weak bones (osteomalacia/rickets), decreased activity of the parathyroid gland (hypoparathyroidism), and a certain muscle disease (latent tetany)

Tetraglycine hydroperiodide is an iodine-containing chemical, used for water purification. Tetraglycine hydroperiodide is marketed in tablets; each tablet effectively disinfects 1 liter of clear water or 0.5 liter of tainted water by releasing approximately 8 mg free iodine. It requires approximately 30 minutes to inactivate target microorganisms and make water bacteriologically suitable for drinking. To remove iodine taste, a vitamin C pill is added to the kit.
Glycine (Cly) is a natural amino acid neurotransmitter that acts as a co-agonist at Glutamate [NMDA] receptors in the brain and is an activator of glycine receptors, GLRA1-3, GLRB. The abnormal Gly levels have been implicated in neuropsychiatric disorders. Alterations in Gly levels are implicated in several diseases of the central nervous system. Glycine was studied in phase II of clinical trials in patients with schizophrenia. The results have shown that using of glycine was associated with reduced symptoms with promising effect sizes and a possibility of improvement in cognitive function. Besides, glycine was also studied in clinical trials phase II in children with cystic fibrosis. The clinical, spirometric and inflammatory status of subjects with cystic fibrosis improved after just 8 weeks of glycine intake, suggesting that this amino acid might constitute a novel therapeutic tool for these patients. In addition, Gly was proposed as a biomarker for brain tumor malignancy. Glycine is a component of a nutrients mixture for peripheral administration to well-nourished mildly catabolic adult patients who require only short-term parenteral nutrition.

Glycerin (glycerol) is 3-carbon alcohol naturally occurring in the human body. It is the structural backbone triacylglycerol molecules, and can also be converted to a glycolytic substrate for subsequent metabolism. Glycerin is a colorless, odorless, viscous, sweet-tasting liquid. The FDA classifies glycerol as "generally recognized as safe". Glycerin is used in the pharmaceutical industry as a sweetener in syrups, lozenges, and as an excipient in eyewash solutions. As an individual prescription product, glycerin has uses as a hyperosmotic, osmotic diuretic, and ophthalmic agent. It may be used as an eye drop in the treatment of glaucoma to reduce intraocular pressure, as a solution or suppository for short-term treatment of constipation, to evacuate the bowel prior to a colonoscopy, and in some ocular surgeries. It may be given intravenously to reduce pressure inside the brain and used externally on the skin as a moisturizer. Glycerin has many other uses in the agricultural, food and pharmaceutical industry.

Kynurenine is a metabolite of the amino acid L-tryptophan used in the production of niacin. Kynurenine is synthesized by the enzyme tryptophan dioxygenase, which is made primarily but not exclusively in the liver, and indoleamine 2,3-dioxygenase, which is made in many tissues in response to immune activation. Kynurenine and its further breakdown products carry out diverse biological functions, including dilating blood vessels during inflammation and regulating the immune response. Evidence suggests that increased kynurenine production may precipitate depressive symptoms associated with interferon treatment for hepatitis C. Cognitive deficits in schizophrenia are associated with imbalances in the enzymes that break down kynurenine. Kynurenine production is increased in Alzheimer's disease and cardiovascular disease where its metabolites are associated with cognitive deficits and depressive symptoms.

Adonitol, also known as ribitol, is the reduced alcohol form of ribose. This compound was first described in 1892 Merck annual report as a crystalline pentahydric alcohol obtained from Adonis vernalis. It is a component of teichoic acids found in the cell walls of Gram positive bacteria. Adonitol is a substrate of the enzyme, called ribitol dehydrogenase, which can be used for direct production of allitol from d-fructose without any by-product formation and this may have potential use as an industrial enzyme. Adonitol is also a moiety present in riboflavin (vitamin B2).
