Promite /ˈproʊmaɪt/ is a dark brown, salty food paste derived from yeast extract.

It is primarily used as a spread on sandwiches and toast similar to Vegemite and Marmite.

Promite was invented in the 1950s by Henry Lewis & Company and marketed under the Masterfoods brand.

Like Vegemite, it is made from leftover brewer's yeast and vegetable extract, however Promite achieves a sweeter taste through the addition of sugar.

According to Mars Customer care, "In 2013, we removed vitamins Thiamin (B1), Riboflavin (B2) and Niacin (B3), as well as two flavour enhancers, and found this to benefit some consumers sensitive to those vitamins, without impacting taste or texture".
