Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Malt Diastase has none that clears that bar.
Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.
No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.
Research strength. Research strength says how much work stands behind the combination. It is never a product score.
Independent record. Every finding is cited to a named trial, dated, and never written by the brand.
20 pairings are live across the library today. Checked 20 July 2026.
No study gave these as a pair, so they are not in the card above. But the reason they belong together is settled biochemistry, not a guess, so it is worth knowing.
Malt diastase is not a distinct enzyme but the historical name for the amylase complex extracted from germinated barley. Adding a separate fungal or bacterial amylase alongside it stacks activity on the same starch bonds, usually with a different pH optimum. Formulators combine them to widen the pH window rather than to add a new function.
Diastase covers starch only. A mixed meal also contains protein and fat, which need protease and lipase respectively. Combination products pair them because the substrates are different, not because the enzymes act on each other. Each enzyme still has its own pH and temperature limits.
These two enzymes hydrolyse completely different bonds. Diastase cannot touch lactose and lactase cannot touch starch. Products combine them to cover a wider range of carbohydrate in a mixed meal. The pairing is coverage, not chemistry between the two.
Pepsin needs a strongly acidic environment, roughly pH 1.5 to 3.5. Malt-derived amylases are near-neutral enzymes and lose activity fast in gastric acid. Putting them in the same immediate-release capsule means one of them is working in conditions that inactivate the other. Enteric or delayed-release design is the usual answer.
Betaine hydrochloride is used specifically to lower stomach pH. Malt diastase has its optimum around pH 5 to 6 and is progressively inactivated below that. Combining the two in one dose works against the amylase activity being paid for. This is a straightforward chemistry conflict worth flagging on a label.
Every alpha-amylase carries at least one tightly bound calcium ion that holds the active-site geometry together. Strip that calcium with a chelator and the enzyme loses activity. This is why calcium salts appear as stabilisers in amylase preparations rather than as a nutritional addition.
Chloride binding near the active site of chloride-dependent alpha-amylases raises catalytic rate. Sodium chloride is therefore present in many amylase assay buffers and stabilised preparations. Whether this matters at supplement doses in a real meal is not established.
The whole point of resistant starch is that it reaches the colon intact to feed gut bacteria. Adding an amylase preparation alongside it works directly against that, hydrolysing a portion in the small intestine where it is absorbed as glucose instead. The two have opposite intentions in the same product.
Inulin is a fructan with beta 2,1 linkages. Amylases cleave alpha 1,4 and alpha 1,6 bonds in glucose polymers and cannot act on fructans. The two coexist without interfering, which is why a prebiotic can sit in the same product as a starch-digesting enzyme without being degraded by it.
Germinating barley activates a suite of hydrolases, phytase among them, alongside the diastatic amylases. In grain-based preparations the two often travel together. Phytase releases phosphate from phytate, diastase breaks down starch. Neither depends on the other.
Chromium turns up alongside starch-directed enzymes in products aimed at carbohydrate-heavy meals. The rationale is thematic rather than biochemical: chromium is discussed in the context of glucose handling while the enzyme acts in the gut lumen. There is no described chemical interaction between them.
