About Rennie
Rennie is the UK's number one bestselling heartburn and indigestion tablet brand, launched in 1931 by John Rennie. With over 90 years of heritage, Rennie has become synonymous with fast, effective relief from digestive discomfort. Over 1 million Rennie tablets are sold on average every day in the UK alone, testament to the brand's trusted reputation. Rennie works by neutralising excess stomach acid, which is often the root cause of heartburn and indigestion. The active ingredients - calcium carbonate and magnesium carbonate - react with stomach acid to form neutral substances, providing almost immediate relief. The chewable tablet format makes Rennie convenient to take anywhere, with no water required. The Rennie range has expanded over the decades to address various digestive concerns. Classic Rennie tablets are available in Peppermint, Spearmint, and Orange flavours, with Sugar Free options for those watching their sugar intake. Rennie Liquid Heartburn Relief offers an alternative format for those who prefer a liquid solution. Rennie Deflatine contains added simeticone to help disperse trapped air bubbles, tackling bloating and wind alongside heartburn. UK supermarkets stock the comprehensive Rennie range including chewable tablets in multiple flavours, liquid suspensions, and combination formulas for wind relief.
