HelloPharmacist Scorecard of Synerpan-5 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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 4 active ingredients.
  • “raw Pancreas concentrate” is listed as a grouped ingredient — the label gives one combined amount (350 mg) without saying how much of each component you get.

Synerpan-5 contains four active ingredients, all digestive enzymes. Bromelain is an enzyme from pineapple that breaks down proteins.

Protease and lipase are also protein- and fat-digesting enzymes, respectively, often derived from pancreatic tissue. Amylase is an enzyme that breaks down carbohydrates.

Together, they're meant to support your digestive system. The capsule itself is made from gelatin and cellulose, with vegetable stearate added as a flow agent.

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, Exercise-induced muscle soreness, Postoperative pain, Postoperative swelling, Rhinosinusitis, bloating — and 2 related terms.
  • The closest evidence on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia (Natural Medicines).
  • Also on file: Bromelain is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness, Rhinosinusitis, Postoperative swelling, Postoperative pain.

The evidence for these enzymes in treating specific conditions is not established in our data. Bromelain has been studied for hay fever, burns, cancer, chemotherapy side effects, circulation problems, and diabetes, but the research is insufficient to rate how well it works for any of these.

Lipase similarly lacks reliable evidence for inflammatory bowel disease or indigestion. Our facts don't include effectiveness ratings for protease or amylase.

If you're considering this product for a particular health goal, it's worth discussing with your pharmacist or doctor whether the evidence supports that use.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Bromelain is generally well tolerated when taken by mouth short-term, though diarrhea, gas, stomach upset, and headache can occur. If inhaled as a powder, bromelain can trigger allergic reactions including asthma, throat itching, and eye irritation—occupational exposure is the main concern here.

Protease and lipase are also generally well tolerated, though digestive upset and allergic reactions are possible; protease exposure in occupational settings has caused asthma and allergic rhinitis. We have no data on bromelain's safety in pregnancy—the safety data advises against it.

Breastfeeding safety is unknown for all three enzymes we have pregnancy/lactation data for, so medical advice is recommended before use. Lipase requires special caution in serious digestive conditions and should only be used under medical guidance.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 3 matched ingredients can interact with medications — Bromelain.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 141 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Synerpan-5, double-check if you're on blood thinners or antiplatelet drugs—bromelain carries a Moderate risk of increased bleeding. Also run through any tetracycline antibiotics you may take, though this is a Minor concern.

No interactions are documented for the protease and lipase in this product.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help some people with general digestion, but evidence for its specific uses is not well established. If you take blood thinners, antiplatelet drugs, or tetracycline antibiotics, check your exact medications with the tool on this page before starting.

Anyone with serious digestive conditions or plans to become pregnant, or who is breastfeeding, should talk with their pharmacist or doctor first.

Anticoagulant/Antiplatelet Drugs

Bromelain may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There is one case report of a patient experiencing minor bruising while taking bromelain with naproxen. Bromelain is thought to have antiplatelet activity. Whether this interaction is of concern with topical bromelain is unclear. Interference with coagulation of burn wounds has been reported in a patient receiving bromelain-based enzymatic debridement. However, observational research has found that topical bromelain debridement is not associated with increases or decreases in laboratory markers of coagulation when compared with surgical debridement.

Likelihood Possible Evidence D
Tetracycline Antibiotics

Theoretically, bromelain might increase levels of tetracycline antibiotics.
Laboratory research suggests that bromelain might increase the absorption of tetracycline antibiotics. However, a study in healthy adults reported no difference in tetracycline plasma levels when a 500 mg dose was taken with or without bromelain 80 mg.
