Promite/ˈproʊmaɪt/ is the registered brand name for a dark brown, salty food paste mainly used as a spread on sandwiches and toast similar to the better-known Vegemite and Marmite. Promite was invented in the 1950s by Henry Lewis & Company and marketed under the Masterfoods brand. Henry Lewis & Company later became MasterFoods Australia and New Zealand, before being bought out by the privately owned Mars family's group of companies in 1967. As Mars Incorporated is a privately owned American company.
Promite is made from vegetables and yeast extract, and is high in various B vitamins. Promite has a sweeter taste, a darker colour and a softer, more spreadable texture than Vegemite.
