How It Works
Take 2 PureBiome™ capsules after your evening meal. Within minutes, the magnesium oxide reaches your stomach and reacts directly with excess hydrochloric acid, neutralising it on contact. Unlike conventional antacids that wear off in minutes, PureBiome™ is poorly absorbed systemically by design, meaning the mineral stays in your stomach lumen and keeps neutralising hour after hour, through the critical 9pm to 3am rebound window when most flare-ups strike. While neutralisation happens at the surface, a small fraction of magnesium is gently absorbed into your bloodstream, replenishing the stores that years of PPI use have quietly depleted. Most users feel relief within 10 to 15 minutes, report sleeping flat within three weeks, and many have successfully tapered off long-term omeprazole using PureBiome™ alongside their GP's deprescribing plan.
