What is this page for?

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
Low disclosure
Vegetarian Enzyme contains four active ingredients: amylase, protease, lipase, and cellulase. These are digestive enzymes—proteins that help break down carbohydrates, proteins, fats, and plant fiber in your food so your body can absorb them.
The product also contains several inactive ingredients (microcrystalline cellulose, hydroxypropyl cellulose, stearic acid, croscarmellose sodium, vegetable stearate, and silica) that form the tablet and help it dissolve.
Does it work?
Not established
The evidence we hold doesn't establish that lipase works for inflammatory bowel disease (IBD), indigestion (dyspepsia), or prematurity—the data is insufficient to rate it. We have no effectiveness ratings for amylase, protease, or cellulase.
If you're considering this product for a specific digestive concern, talk with your pharmacist about whether the science supports it for your situation.
How safe is it?
Well-documented data
Protease and lipase are generally well tolerated in adults but may cause digestive upset or allergic reactions in some people. Rarely, occupational exposure to airborne protease can trigger allergic rhinitis or asthma; this is mainly a concern for industrial workers, not supplement users.
Lipase is not recommended in pregnancy or while breastfeeding without medical advice—the safety data is limited. Protease should be avoided in pregnancy unless your doctor prescribes it.
If you have serious digestive conditions, check with your healthcare provider before starting.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That said, we have no data on amylase or cellulase, so mention those names to your pharmacist if you take any medications.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.
This product is a straightforward digestive enzyme blend that's generally well tolerated by most adults. If you're pregnant or breastfeeding, have a serious digestive disorder, or take any medications, talk with your pharmacist or doctor first.
