A water-soluble B vitamin that is a necessary cofactor in alpha-keto decarboxylation, links glycolysis with the Krebs cycle (tricarboxylic acid cycle, the main source of energy in mammals), and is critical in the production of cyclic guanosine monophosphate. Thiamin aids in digestion; improves tolerance to pain; is useful against psoriasis, shingles and seborrhoeic dermatitis; and reduces gastric acidity.
