As written on the jar - "Marmite is Australia's original yeast spread. Long valued as an excellent source of Vitamin B Complex, now Marmite is packed with even more goodness. They have added Folate, B12 and Iron - essential nutrients for us all. Folate is particularly important for Mum's to be and also helps us use the energy from the foods we eat. B12 and iron are vital for good health and peak performance. Marmite provides a tasty 'meat free' source of B12 and iron. Marmite is so versatile too. Try it with avocado on hot toast, fresh bread or crackers. It is also a tasty addition to stir-fries and soups. Enjoy!" Size: 10oz (250grams)
