What is Rennie Heartburn, Indigestion & Wind Relief?

Rennie Heartburn, Indigestion & Wind Relief is an antacid treatment that works to neutralise excess stomach acid. These tablets can treat a number of conditions including heartburn, indigestion, trapped wind, and an upset stomach. This is thanks to the active ingredients that are contained in the tablets. These are:

  • Calcium carbonate
  • Magnesium carbonate
  • Simeticone

Calcium carbonate and magnesium carbonate are both antacids that work to reduce the levels of stomach acid. Simeticone is known as an anti-foaming agent that reduces bloating and pain caused by excessive gas in the stomach.

  • A hiatus hernia
