What is Numark Heartburn and Indigestion Liquid?

Numark Heartburn and Indigestion Liquid is a soothing remedy for symptoms of indigestion. It gets to work quickly, neutralising excess stomach acid and relieving any irritation and the burning sensation known as heartburn. This product can be used by anyone over the age of 6, and its combination of three active ingredients is ideal for those experiencing heartburn and indigestion and looking for an all-in-one remedy.


What is heartburn?

Heartburn is a common problem which is caused by acid reflux. When you have acid reflux, your stomach acid tries to work its way upwards from your stomach to your throat through your oesophagus. This acid causes irritation in your chest, which is what you’ll know as heartburn. Some of the other symptoms of acid reflux include:

  • Bad breath
  • A cough
  • Hiccoughs
  • An unpleasant taste in the mouth
  • Hoarseness
  • Bloating
  • Feeling sick


How will Numark Heartburn and Indigestion Liquid help to ease my heartburn?

This medication contains three active ingredients which help to ease heartburn and indigestion. The first two are sodium bicarbonate and calcium carbonate, which both work as antacids, helping to neutralise any excess stomach acid, keeping it from causing irritation to your stomach lining and food pipe. The third ingredient is sodium alginate, which works as a reflux suppressant, creating a protective layer over your stomach contents which keeps stomach acid from moving up towards your throat. This dual action method helps to ease acid reflux and heartburn quickly.
