A minor or very limited concern, such as being an ultra-processing marker only. The concern level sets how many points mannitol costs on a product’s receipt.

What the evidence says

  • Laxative effect in large amountsRegulatory

    Large amounts can have a laxative effect; the EU requires a label statement above 10% added polyols and the US for some polyols above set intakes. [1][2]

Evidence tiers say how sure the evidence is, separately from how much it matters. About evidence tiers.
