HelloPharmacist Scorecard of Vegetarian Enzyme by Douglas Laboratories

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 4 of its 4 active ingredients.
  • “Vegetarian Enzyme Concentrate” is listed as a grouped ingredient — the label gives one combined amount (450 mg) without saying how much of each component you get.

This product contains 4 active ingredients, all digestive enzymes: amylase (breaks down carbohydrates), protease (breaks down proteins), lipase (breaks down fats), and cellulase (breaks down plant fiber). These work together to help your body digest food.

The rest of the tablet is made up of inactive ingredients like cellulose and silica, which are binders and flow agents.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: digestive enzyme support.
  • We looked for evidence on: Dyspepsia, indigestion, pancreatic insufficiency, malabsorption.
  • The closest evidence on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia (Natural Medicines).

The evidence for these enzymes is limited. For protease and lipase, we hold no effectiveness ratings in our data.

For lipase specifically, the evidence we do have for inflammatory bowel disease and indigestion is rated insufficient — meaning we don't yet have solid proof it works for those uses. If you're taking this for digestive support, talk with your doctor about whether the benefit matches what you're hoping for.

The evidence, ingredient by ingredient Proteolytic Enzymes (proteases) Lipase

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Protease and lipase are generally well tolerated by most adults, though some people report mild digestive upset. Rarely, people exposed to protease dust (mainly in workplace settings like laundry facilities) have had allergic reactions including rhinitis or asthma.

Regarding pregnancy: protease safety hasn't been established, so it's best avoided unless your doctor prescribes it. For lipase, there's little safety data in pregnancy, so check with your doctor first.

During breastfeeding, neither protease nor lipase has been well studied — ask your healthcare provider before using.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 2 matched ingredients has a documented medication interaction on file.

No interactions are documented for the ingredients we could check in this product. Amylase and cellulase were not checked because we hold no data for them — so if you're on multiple medications, it's still worth running your full list through the tool below to be certain.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.

This enzyme blend is straightforward for general digestive support and has no known drug interactions. If you're pregnant or breastfeeding, you'll want to confirm with your doctor or pharmacist first, since the safety data is limited for both enzymes.

If you have a serious digestive condition, use it only under medical guidance. Run your exact medications through the checker on this page just to be thorough.

Vegetarian Enzyme by Douglas Laboratories: Common Questions

Does Vegetarian Enzyme by Douglas Laboratories interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Vegetarian Enzyme. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Vegetarian Enzyme contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant?
The safety data for both protease and lipase in pregnancy is limited. Protease is best avoided during pregnancy unless your doctor prescribes it. For lipase, there's not enough data to know either way — talk with your doctor or pharmacist before starting it.
Is it safe while breastfeeding?
There's little safety data on either protease or lipase during breastfeeding. Check with your healthcare provider first before using this product.
What are the side effects?
Most people tolerate these enzymes well, but some report mild digestive upset. Rarely, occupational exposure to airborne protease (mainly in industrial settings) has triggered allergic reactions like hay fever or asthma in sensitive people.
Does this actually help with digestion?
The evidence that it works is limited. We don't have solid proof it helps with indigestion or inflammatory bowel disease. If you want to know whether it's the right choice for your situation, ask your doctor.
Can I take this with my medications?
The enzymes we could fully check — protease and lipase — have no documented interactions with any medications. We couldn't check amylase and cellulase, but you can use the interaction checker on this page with your exact medication list to be sure.
