Red grapefruit juice, not from concentrate and not fortified, is freshly pressed juice from pink or red grapefruit varieties. It is a good source of vitamin C and provides lycopene and other carotenoids from the red flesh, but lacks the fibre of the whole fruit.
Juicing removes the fibre and exposes vitamin C to air and light, which slowly degrades it; drink soon after opening and keep chilled. Grapefruit juice can interact with certain medications.

* % 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.
