Interesting! And weird. LolOfficially, Vegemite is "brewer's yeast extract, with various vegetable and spice additives." Again, if prepared properly, it's not bad. I had it spread over butter on toast and I know a lot of vegans who use it to add a meaty/salty flavor to soups and certain dishes. The flavor reminds me of Vietnamese fish sauce: salty, but with a slight malt-flavor you don't get in fish sauce. Both are natural sources of glutamate, but Vegemite also is an excellent source of B vitamins (B1, B2, B3 & B9) and is often fortified with iron, B6, and B12. It's also high in potassium.
