Additives4 additives · 4 limited risk
Seed oilFatLimited risk
ClearShelf standard: we lower the Ingredients score when seed oils are used. This is our house standard, not a medical claim. Research is mixed; major health groups have not found harm at typical intakes.
Natural flavoursFlavouringLimited risk
An undisclosed mix of extracts and carriers; the label doesn’t say what’s in it or how it was made.
MSG (monosodium glutamate) (E621)Flavour enhancerLimited risk
Considered safe; EFSA set an acceptable daily intake in 2017, and some people report short-lived symptoms.
Disodium inosinate or guanylate (E627, E631)Flavour enhancerLimited risk
Usually paired with MSG; a source of purines, which people with gout are told to limit.
Matched from the ingredient list. Risk levels summarise findings from EFSA, the FDA, IARC and published studies; they explain a concern, not a diagnosis.
