Apple Cider Vinegar for Stomach Acid Production
Apple cider vinegar does not meaningfully change gastric acid production.
Overview
Verdict
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- Not recommended for acid production
- Expected timeframe
- n/a
Protocol
- safety
- Taking vinegar for reflux or suspected ulcer symptoms can worsen mucosal irritation
- instead
- If you suspect low stomach acid, ask for proper assessment - H. pylori testing, ferritin and B12 levels - rather than self-treating
- studied dose
- 1-2 tablespoons diluted before meals in glycaemic research; no trial has measured gastric acid output
- evidence note
- Verdict is no - vinegar does not increase gastric acid secretion, and no trial supports this use
- what happened
- No effect on acid secretion has been demonstrated. The acidity you taste is acetic acid in the mouth and stomach lumen, not stimulated parietal cell output. Its modest glycaemic evidence works through delayed gastric emptying and starch digestion - a separate mechanism entirely
