What Antacids Like Rennie and Gaviscon Do to Your Digestion Over Time

A chalky tablet after a big meal feels harmless enough — but reach for antacids day in, day out, and they can start to mask more than they fix.

Here’s what regular antacids can do to your digestion over time, and the gentler natural alternatives people turn to.

What regular antacids do to your digestion

Antacids neutralise acid on the spot, but leaning on them constantly can throw things off balance.

  • A masked underlying cause, daily use can hide reflux or a food trigger that deserves attention.
  • Mineral balance, some antacids affect how you handle magnesium, calcium and aluminium.
  • A little acid rebound, constant neutralising can prompt the stomach to make more.

The short version: antacids patch the moment but can mask the cause and unsettle balance — gentler support helps digestion work properly.

Your natural toolkit — and which to reach for

Here are the gentle natural picks people reach for to settle indigestion.

Gastricumheel — reach for this if you want everyday tummy-settling support.

Duodenoheel — reach for this if reflux and upper-gut discomfort recur.

Nux Vomica Homaccord — reach for this if rich food and overindulgence are the trigger.

Simple things that genuinely help

  • Notice which foods reliably set off your indigestion.
  • Eat slowly and stop before you’re overfull.
  • Leave a few hours between your last meal and bed.
  • See your GP for indigestion that keeps coming back.

The bottom line

Good digestion is worth more than a quick neutralise. With gentle natural support and a few mindful habits, your stomach can settle more genuinely — and United Remedies is here to help it along.
