Frequently Asked Questions

How do I know if I have low stomach acid?

Symptoms of low stomach acid include bloating within 30 minutes of eating, feeling full quickly, undigested food in stool, and frequent SIBO. The gold standard test is the Heidelberg pH capsule test, but it is rarely available. Many practitioners use a "betaine HCl challenge" — if 650mg with a meal causes no warmth/discomfort, low acid is suspected.

Can betaine HCl cause ulcers?

Betaine HCl should not cause ulcers in individuals with healthy gastric mucosa. However, it is strictly contraindicated in anyone with active ulcers, gastritis, or H. pylori infection, as additional acid would worsen these conditions. Never combine with NSAIDs. Always start with a low dose and titrate up.

Is betaine HCl the same as betaine (TMG)?

No. Betaine HCl (betaine hydrochloride) is used to supplement stomach acid. Betaine (trimethylglycine/TMG) is a methyl donor used for homocysteine metabolism and liver health. They share the betaine molecule but have different primary uses. Check labels carefully.
