Yeast extract

Yeast extract is a concentrated paste made from yeast, used as a spread or flavouring. The figures here describe a mixed sample including Marmite and own-brand products. It provides protein and several B vitamins. Per 100g, it contains 41g of protein, 11g of salt, 15µg of vitamin B12 and 2620µg of folate.

Protein is needed for the growth and repair of body tissues. Vitamin B12 and folate help the body make red blood cells, and vitamin B12 also supports normal nerve function. Yeast extract has a high salt content, which is worth noting for people monitoring their salt intake. The amount consumed affects how much salt and other nutrients it provides.
