Rennies Tablets Spearmint 48

Rennie is the portable antacid: calcium carbonate with magnesium carbonate in a chewable mint tablet that starts neutralising stomach acid as you chew. Calcium carbonate is the strongest simple acid neutraliser per gram, the magnesium salt balances its slightly constipating tendency, and the format needs no water, no fizz and no planning, which is why a strip lives in so many handbags and desk drawers. Relief typically arrives within minutes and lasts an hour or two. Spearmint 48 is the softer-mint mid-size of the chewable classic.

Heartburn does not schedule itself. A chewable that works anywhere, dissolved by your own saliva, is the difference between relief in traffic and suffering until you get home. Speed matters too: chewing starts neutralising in the mouth and the relief lands within minutes, faster than anything that must first dissolve in the stomach.
