Vegetable stock cubes are concentrated flavouring blocks made from dehydrated vegetables, salt, yeast extract, and herbs. They are used in small quantities (typically one cube per 500ml water) to flavour soups, stews, and sauces. They are extremely high in sodium per 100g (often 20–25g sodium/100g) but per serving (typically a 5g cube in 500ml water) contribute around 600–900mg sodium to the dish — still a significant proportion of the 2,400mg daily limit.
Use reduced-salt stock cubes where available, or use half a cube and rely on herbs and spices for additional flavour. Adding stock to dishes already containing processed or salted ingredients such as canned tomatoes or soy sauce can push total sodium intake very high.

* % Daily Value is the proportion of an adult
EU Nutrient Reference Value (NRV) supplied by 100g of this food.
NRVs are the labelling standard — the same basis as the “%RI” figures printed on
food packaging — so these percentages are directly comparable with a shop label.
They are a single adult figure and do not vary by age or sex, which is why they
sometimes differ from UK dietary reference values: the NRV for vitamin C is 80mg
where the UK RNI is 40mg. When Nutriofia assesses your own intake in the
reports and trackers, it uses the age- and sex-specific UK values instead.
Fibre is shown without a percentage. Our fibre values use the UK
Englyst NSP method, while the published 30g daily goal is an AOAC figure — the two
are measured differently and a single percentage would mislead.
