Rennie is a Bayer over-the-counter chewable antacid containing calcium carbonate 680 mg and heavy magnesium carbonate 80 mg; both actives are FDA OTC antacid monograph ingredients sold in the US, but no US-marketed product pairs them, as Tums is calcium carbonate alone and Rolaids combines calcium carbonate with magnesium hydroxide rather than magnesium carbonate.
