Research review
Does digestive enzymes help with stress? What the research does and doesn't show
"Digestive enzymes for stress" is a search with no research behind it. No trial has measured a digestive-enzyme supplement against stress, cortisol, or stress-linked digestive symptoms, including DigeZyme's own trial.
The evidence doesn't support digestive enzyme supplements, including DigeZyme, as a way to manage stress or stress-related digestive symptoms. No trial has tested DigeZyme, or a comparable blend, against a measure of stress, cortisol, or stress-triggered bloating and discomfort — the research on this ingredient hasn't gone there.
What the evidence doesn't support
It doesn't support digestive enzyme supplements as something that reduces stress, or as a fix for digestive symptoms that show up specifically during stressful periods. We haven't found a controlled trial that measured stress, cortisol, or a stress-related symptom score alongside a digestive-enzyme supplement.
What the trials found
The one placebo-controlled trial of DigeZyme itself studied 40 adults with functional dyspepsia, taking 150 mg/day for 60 days, and measured symptom questionnaires — bloating, fullness, discomfort — not stress, anxiety, or cortisol. Functional dyspepsia and stress are often discussed together in the broader gastroenterology literature, but this trial didn't screen for stress levels, test that connection, or report on it.
We haven't found any other controlled trial testing digestive enzyme supplementation specifically for stress, or for digestive symptoms a person attributes to stress.
Questions people ask
Can digestive enzymes help with stress?
We haven't found a trial testing this. No research we're aware of has measured digestive enzyme supplementation against a stress or cortisol outcome.
Does stress cause a need for digestive enzymes?
We haven't found controlled research measuring whether psychological stress changes how much of its own enzymes a healthy person's digestive system produces. That's a real gap in what's been studied, not something we can answer either way.
Do digestive enzymes help with stress-related bloating?
No trial we've found has tested digestive enzyme supplementation for bloating specifically tied to stress. The one DigeZyme trial measured general dyspepsia symptoms, not a stress-linked subgroup.
Do digestive enzymes help with stress eating or appetite?
No trial has tested DigeZyme, or any digestive-enzyme supplement, for appetite or stress-related eating patterns. That's a separate question from digestion itself, and it's untested here too.
When to talk to a doctor
Digestive symptoms that show up consistently with stress, or stress itself that's affecting daily life, are worth discussing with a doctor — a digestive-enzyme supplement is not a treatment for either. See digestive enzymes: what the research does and doesn't show for the wider research picture.

- Evaluation of the Safety and Efficacy of a Multienzyme Complex in Patients with Functional Dyspepsia: A Randomized, Double-Blind, Placebo-Controlled Study A 2018 placebo-controlled trial found that adults with functional dyspepsia who took DigeZyme (150 mg/day) for 60 days scored significantly better on several symptom questionnaires than those given a placebo, with no reported product-related side effects; the trial was run and funded by DigeZyme's own maker.
