KAL Betaine HCl+ targets stomach-acid and protein-digestion support, but at 328mg of **Betaine HCl** per tablet it lands below the doses digestive protocols typically use. The idea is to add hydrochloric acid to your stomach to help break down protein when your own acid is suspected to be low. Your label shows this as 250mg of betaine from 328mg of betaine hydrochloride, while the typical digestive range runs 650–2,500mg and the one study that actually measured its effect on stomach acid used 1,500mg — so a single tablet gives you roughly half the usual starting amount. Evidence is limited overall: no controlled trials have shown betaine HCl improves digestion or nutrient absorption.

The 130mg of **Pepsin** pairs with the acid as a protein-digesting enzyme and sits inside the typical 50–300mg formulation range. The catch is that pepsin's strength is properly measured in activity units, not milligrams, so the 130mg figure alone doesn't tell you how active it is — and no controlled human trials back supplemental pepsin for digestive outcomes. The 32mg of calcium comes from calcium carbonate in the tablet base, far below a dose that contributes to any health goal.

The label suggests one tablet with a meal, so reaching the 650mg+ that digestive protocols start from would mean two or more per meal. Worth knowing: betaine HCl can trigger heartburn or stomach irritation, especially if your stomach acid isn't genuinely low — this is a targeted tool for suspected low stomach acid, not a general digestive aid.
