A single capsule. A definitive answer. The Heidelberg pH Capsule measures acid secretion as it happens — no blood draw, no scope, no guesswork.
A vitamin-sized capsule
Real-time pH
Your stomach acid
You were told you had too much acid. You took the medication. Months turned into years. The symptoms never fully resolved. Nobody measured whether acid was actually the problem.
Learn about reflux and stomach acid →The antimicrobials worked. For a while. Then the bloating returned, the breath test turned positive, and you started another round. Nobody checked whether your stomach acid was letting bacteria through in the first place.
Learn about SIBO and stomach acid →Your B12 is low. Your iron won't budge. You take everything your practitioner recommends and your levels barely move. The problem may not be what you're taking. It may be what your stomach isn't doing with it.
Learn about nutrient malabsorption →Bloating after every meal. Undigested food. Fatigue that no one can explain. Your bloodwork comes back fine. Your endoscopy is clean. But something is clearly wrong and nobody can tell you what.
Learn about low stomach acid →When your symptoms don't match any diagnosis.
When the real problem is too little acid, not too much.
Why bacterial overgrowth keeps returning.
When the cells that make acid are being destroyed.
A different problem that looks like acid reflux.
What's actually happening after years of suppression.
When supplements aren't absorbing no matter what you try.
The slow decline most people never discover.
Visible proof that something upstream isn't working.
A single test can reshape the conversation between you and your practitioner.
Replace trial-and-error prescribing with a direct measurement of what your stomach is actually doing.
If acid is already low, suppressing it further makes things worse. The data shows which direction to go.
Bloating, reflux, SIBO, and deficiencies can all trace back to one cause. Knowing your acid status changes everything.
No more wondering whether the medication is right. You and your practitioner decide based on real evidence.
One test. One hour. A definitive answer about your stomach acid.
