HelloPharmacist Scorecard of Pan-Ox-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.

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 6 of its 13 active ingredients.
  • “Pancreatin” is listed as a grouped ingredient — the label gives one combined amount (37.50 mg) without saying how much of each component you get.

Pan-Ox-5 contains 13 active ingredients: three digestive enzymes (protease, lipase, and pepsin) that help break down proteins and fats; pancreatin, a blend of enzymes; and plant and food-derived compounds — beet root powder, citrus pectin, betaine hydrochloride, papain, plus amylase, glutamic acid, diastase, ox bile powder, and vegetable rennet. The enzymes and bile are meant to support digestion.

The product also contains inactive ingredients like microcrystalline cellulose, rice bran, and silica as fillers and binders.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Digestive enzyme support with papain and proteases.
  • We looked for evidence on: Dyspepsia, Diarrhea, Irritable bowel syndrome (IBS), Inflammatory bowel disease (IBD), Exercise-induced muscle soreness, Exercise-induced muscle damage — and 4 related terms.
  • The strongest evidence on file: Beet is rated "Possibly Effective" for Exercise-induced muscle soreness (Natural Medicines).
  • Also on file: Papain is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness, Wound healing.
  • Also on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Inflammatory bowel disease (IBD), Dyspepsia.

The evidence for most ingredients in this product is not established or is mixed. Beet root powder is possibly effective for athletic performance and exercise-induced muscle soreness.

Citrus pectin is possibly effective for high cholesterol. For the other ingredients — protease, pepsin, lipase, papain, betaine HCl, and the rest — the evidence is insufficient to rate their effectiveness for the conditions studied, or no effectiveness data is held in our system.

The evidence, ingredient by ingredient Beet Pectin Betaine Hydrochloride Lipase Proteolytic Enzymes (proteases) Papain

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 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Protease and pepsin are generally well tolerated but may cause digestive upset or allergic reactions; rare occupational airborne exposures have triggered asthma or allergic rhinitis. Lipase is generally well tolerated in supplement form, though adverse effects in infants and pregnancy safety have not been thoroughly studied.

Beet root powder is well tolerated as a food and short-term supplement; the most common effect is red or black stools (harmless), though large amounts could theoretically cause low blood calcium or kidney damage. Betaine HCl may irritate the stomach and is not safe for people with ulcers, gastritis, or acid reflux.

Citrus pectin is generally well tolerated but can rarely cause diarrhea, gas, or mild cramps, and allergic reactions are rare but possible. Papain is well tolerated as a food or supplement at normal doses but can cause allergic reactions and, at high doses, rare severe stomach or esophageal problems.

Safety data in pregnancy and breastfeeding is limited or absent for most ingredients; avoid papain and betaine HCl in pregnancy, and discuss with your doctor or pharmacist before use during pregnancy or breastfeeding.

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?
  • 4 of the 6 matched ingredients can interact with medications — Papain, Beet, Betaine Hydrochloride, Pectin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications.
  • For scale: 904 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 Pan-Ox-5, double-check warfarin (blood thinner) — papain may raise its effect to unsafe levels. Also confirm any medications processed by the liver enzyme CYP3A4, lovastatin, tetracycline antibiotics, digoxin, H2-blockers, antacids, and proton pump inhibitors — citrus pectin and beet root powder may reduce how well they work.

No interactions are documented for the other checked ingredients.

Each ingredient & the kinds of drugs it affects

For each ingredient in Pan-Ox-5 with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Beet root powder3 drug types · 861 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.

Likelihood Possible Evidence D
Antihypertensive Drugs

Beet and beetroot contain nitrates, which can cause vasodilation, potentially leading to lower blood pressure. However, a study published in the European Journal of Clinical Nutrition using concentrated beetroot juice found no significant impact on blood pressure or heart rate in different age groups. Other small clinical studies suggest that while beet consumption might transiently lower blood pressure due to vessel dilation, there's no consistent evidence of a lasting effect. Overall, the theoretical risk of reduced blood pressure due to beet's nitrate content exists, but studies generally indicate a low and temporary impact rather than a sustained decrease.

Likelihood Possible Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, beet might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research suggests that beet induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Beet root powder full monograph & interactions

Betaine HCl3 drug types · 36 drugs

Antacids

Betaine hydrochloride increases stomach acidity and could decrease the effects of antacids.
In human research, betaine hydrochloride increases stomach acidity. Antacids are taken to decrease stomach acidity. Theoretically, taking betaine hydrochloride along with antacids might decrease the effects of the antacids.

Likelihood Possible Evidence D
H2-Blockers

Betaine hydrochloride increases stomach acidity and could decrease the effects of H2-blockers.
In human research, betaine hydrochloride increases stomach acidity. H2-blockers are used to decrease stomach acidity. Theoretically, taking betaine hydrochloride along with H2-blockers might decrease the effects of H2-blockers.

Likelihood Possible Evidence D
Proton Pump Inhibitors (Ppis)

Betaine hydrochloride increases stomach acidity and could decrease the effects of PPIs.
In human research, betaine hydrochloride increases stomach acidity. PPIs are used to decrease stomach acidity. Theoretically, taking betaine hydrochloride along with PPIs might decrease the effects of PPIs

Likelihood Possible Evidence D
Betaine HCl full monograph & interactions

Citrus Pectin3 drug types · 23 drugs

Digoxin (Lanoxin)

Theoretically, pectin might reduce the absorption of digoxin, potentially decreasing its effectiveness.
A small clinical study shows that taking digoxin with a kaolin-pectin suspension reduces the absorption of digoxin by about 62%. It is unclear if these effects are due to pectin, kaolin, or the combination.

Likelihood Possible Evidence B
Lovastatin (Mevacor)

Theoretically, pectin might reduce the absorption of lovastatin, potentially decreasing its effectiveness.
Case reports suggest that concomitant use of pectin and lovastatin might reduce the cholesterol-lowering effect of lovastatin, possibly due to reduced intestinal absorption of lovastatin.

Likelihood Possible Evidence D
Tetracycline Antibiotics

Theoretically, pectin might reduce the absorption of tetracycline antibiotics, potentially decreasing their effectiveness.
A small clinical study shows that taking tetracycline with bismuth subsalicylate in a kaolin-pectin suspension reduces the absorption of tetracycline by about 34%. It is unclear if these effects are due to pectin, kaolin, bismuth subsalicylate, or the combination.

Likelihood Possible Evidence B
Citrus Pectin full monograph & interactions

Papain1 drug type · 2 drugs

Warfarin (Coumadin)

Theoretically, papain might increase the effects and side effects of warfarin.
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract.

Pan-Ox-5 by Douglas Laboratories: Common Questions

Does Pan-Ox-5 by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, Pan-Ox-5 has a known interaction with 903 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pan-Ox-5 contains 13 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 Pan-Ox-5 if I'm pregnant or breastfeeding?
Safety data is limited for most ingredients in this product. Papain and betaine HCl should be avoided in pregnancy. For the others — protease, lipase, beet, citrus pectin — there isn't enough data to know either way. Talk with your doctor or pharmacist for personalized advice.
What are the digestive enzymes in this product supposed to do?
Protease, pepsin, lipase, amylase, diastase, and pancreatin are meant to break down proteins, fats, and carbohydrates in food to aid digestion. Ox bile supports fat digestion as well. The evidence that they're effective for digestive conditions is insufficient in our data.
Will this product turn my stool red or dark?
Yes — beet root powder commonly causes red stools and can sometimes cause black stools. This is harmless and not a sign of bleeding.
Is beet root powder safe as a food versus a supplement?
Beet as a food is generally well tolerated. Concentrated beet supplements lack safety data, so use caution with supplement forms.
Can I take this if I have acid reflux or stomach ulcers?
No — betaine HCl in this product increases stomach acid and is not safe for people with ulcers, gastritis, or acid reflux, as it could irritate your condition.
What should I know about papain in this product?
Papain can increase the blood-thinning effect of warfarin to unsafe levels — a documented case showed an INR spike after papain supplement use. It's generally well tolerated at normal doses but can cause allergic reactions. Avoid it in pregnancy.
