Antacids

Calcium carbonate to relieve gastric acid complaints

Our pharmaceutical-grade precipitated calcium carbonates contain alkaline ions that render stomach acid more neutral and counteract symptoms linked to excess stomach acids, such as acid reflux, heartburn and indigestion.

Highly soluble, our calcium carbonates contain alkaline ions that chemically neutralize gastric acid, reducing damage and relieving pain.

We recommend our Calcius™ range for antacids

Our Calcius range is suitable as an active pharmaceutical ingredient in swallowable, effervescent and chewable antacid products as well as antacids in powder form.
