Digestive enzymes and protein

Protease, one of the five enzymes in a blend like DigeZyme, is specifically built to break protein into smaller peptides and amino acids — the same job the body's own digestive proteases do. Whether adding more of it to a protein shake or a high-protein meal changes digestion or reduces gas hasn't been tested for DigeZyme itself; the one relevant lab study used a different product.

What protease actually does to protein

Protease works the same way in a supplement as it does naturally in the stomach and small intestine: it breaks the chemical bonds holding amino acids together in a protein chain, producing shorter peptides and free amino acids the gut can absorb. That's true whether the protein comes from a whole food or a whey protein powder — the enzyme doesn't distinguish between protein sources, it acts on the bond itself.

The lab evidence for faster breakdown

A 2024 study ran a digestive-enzyme blend (DigeSEB Super, made by a different manufacturer, not DigeZyme) through a simulated digestion model and found statistically higher release of amino acids and improved protein breakdown compared with a no-enzyme control, alongside faster starch and fat breakdown. That's a real mechanism finding — enzymes can measurably speed up protein digestion outside the body — but it used lab equipment, not a person, and tested a different product from DigeZyme. It doesn't tell us whether taking DigeZyme with a protein shake changes how a person actually digests or feels afterward.

What hasn't been tested

We haven't found a trial testing DigeZyme, or a comparable enzyme blend, specifically alongside whey protein or a protein shake, for digestion speed, gas, bloating, or how much protein the body absorbs. The "protein farts" and bloating some people report after a protein shake are more commonly attributed to lactose (in whey concentrate) or to the amount of protein consumed at once than to a lack of protease specifically — but that's a general explanation, not something a DigeZyme trial has tested directly.

Questions people ask

Do digestive enzymes help you absorb more protein from a shake?

No trial we've found tests this directly for DigeZyme or a comparable blend. The lab study above shows protease can speed up protein breakdown in a simulated digestion model, but that's not the same as showing a person absorbs more protein overall from a shake when taking an enzyme supplement alongside it.

Do digestive enzymes reduce gas from protein powder?

We haven't found a trial testing this. If gas after a protein shake is a lactose issue rather than a protein one, a lactase-containing blend like DigeZyme could plausibly help with that specific piece — but that's a mechanistic possibility, not a tested result for reducing gas from a protein shake overall.

Should I take digestive enzymes with my protein shake?

That's a personal choice the research doesn't settle either way for this specific pairing. See when is the best time to take digestive enzymes for what the trial data does say about timing relative to a meal, and what is DigeZyme for what each of its five enzymes targets.
