What to know before buying

The stated relief duration of up to four hours is a manufacturer claim, not an independently established result. Always read the label. The listing advises speaking to a doctor or pharmacist before use during pregnancy. It also lists sodium, calcium and the preservatives methyl (E218) and propyl (E216) parahydroxybenzoates. The description refers to tablets when discussing sugar and gluten, so those statements should not be assumed to describe this liquid.

Who is it for?

A good fit for

People seeking a liquid-format product marketed for heartburn, indigestion or acid reflux.
Buyers who prefer aniseed flavour and a larger 500ml bottle.

Less suited to

People who need a sugar-free or gluten-free assurance for this specific liquid, as the listing's statements on those ingredients refer to tablets.
