Betaine HCl
Also known as: betaine hydrochloride, betaine with pepsin
Betaine HCl is a compound that releases hydrochloric acid in the stomach and temporarily acidifies its contents. It is used when low stomach acid is suspected, often together with pepsin or bitter herbs.
What it is used for
- protein digestion with low stomach acid – weak evidence, small studies show short-term acidification
- bloating and heaviness after meals – weak evidence
Forms and how they differ
betaine HCl
on its own, dose per capsule varies
betaine HCl + pepsin
pepsin breaks down protein
betaine HCl + gentian
the bitter herb stimulates digestive juices – quality depends on the label
Pairs well with
Protein meals; digestive enzymes.
Do not combine / separate
Do not combine with anti-inflammatory painkillers (NSAIDs), corticosteroids or acid-reducing medicines.
Watch out for
Not suitable with stomach or duodenal ulcers, gastritis or heartburn. During pregnancy or breastfeeding, with kidney or liver disease, or when taking medicines, consult your doctor. Do not self-diagnose low stomach acid.
Safety
A burning or warm feeling in the stomach is a signal to stop taking it. Do not exceed the label dose.
Practical tip
Heartburn is more often caused by something other than low acid – discuss it with your doctor first.
