Vegetarian Enzyme Ingredients & Drug Interactions
What is this page for?
First and foremost: checking Vegetarian Enzyme against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.
Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

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.
What’s inside
Full disclosure
This product contains 4 active ingredients: three digestive enzymes (Amylase, Protease, and Lipase) plus Cellulase, along with a vegetarian enzyme concentrate blend. The enzymes work to break down carbohydrates, proteins, fats, and plant fiber in food.
The tablet also contains several inactive ingredients — cellulose, hydroxypropylcellulose, croscarmellose sodium, stearic acid, vegetable stearate, and silica — which are fillers, binders, and flow agents typical in tablet manufacturing.
Does it work?
Not established
The evidence for Lipase is not established for the conditions studied in our data — inflammatory bowel disease and dyspepsia both carry a rating of insufficient reliable evidence. We hold no effectiveness ratings for Amylase, Protease, or Cellulase.
If you're considering this product for a specific digestive concern, talk to your pharmacist about what the research actually supports.
How safe is it?
Well-documented data
Protease and Lipase are generally well tolerated in most adults, though some people report digestive upset or allergic reactions. Protease exposure — even occupational airborne contact — has rarely triggered allergic rhinitis (nasal and eye inflammation) or asthma in case reports.
Lipase has not been thoroughly studied for safety outcomes; no adverse effects have been reported in adults, but the data is limited. For pregnancy: safety data on supplemental Protease and Lipase is thin or absent, so both should be used only if your doctor advises it.
For breastfeeding: the same applies — check with your healthcare provider first. Do not give this product to premature infants; lipase has caused serious gastrointestinal harm in that population.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. If you take any medications, use the search tool on this page to verify, or ask your pharmacist.
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 is a straightforward enzyme blend with no known drug interactions for the ingredients we could verify. It's generally well tolerated by healthy adults, but digestive enzyme supplements aren't yet proven for common conditions like bloating or indigestion.
If you're pregnant, breastfeeding, or have a serious digestive condition, talk to your pharmacist before starting.
