HelloPharmacist Scorecard of Multi-Enzyme by The Vitamin Shoppe

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 5 of its 14 active ingredients.
  • “Pancreatin” is listed as a grouped ingredient — the label gives one combined amount (100 mg) without saying how much of each component you get.

Multi-Enzyme by The Vitamin Shoppe contains 14 active ingredients—a blend of digestive enzymes and minerals designed to support digestion. The enzymes include amylase (breaks down carbohydrates), papain and bromelain (protein-digesting enzymes from papaya and pineapple), protease (another protein enzyme), lipase (breaks down fats), pepsin (stomach enzyme), and cellulase (breaks down plant fiber).

You'll also get calcium, phosphorus, betaine hydrochloride (an acidifying agent), and ox bile powder (aids fat digestion). The tablet or pill contains inactive ingredients like microcrystalline cellulose, magnesium stearate, and silicon dioxide—standard binders and flow agents.

Does it work?

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: protein carbohydrate and fat digestion.
  • We looked for evidence on: Dyspepsia, Exercise-induced muscle damage, Exercise-induced muscle soreness, Postoperative swelling, indigestion, bloating and gas — and 2 related terms.
  • The strongest evidence on file: Calcium is rated "Effective" for Dyspepsia (Natural Medicines).
  • Also on file: Papain is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness.
  • Also on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia.

The evidence for most ingredients in this product isn't well established in the data we hold. Papain, bromelain, protease, lipase, and betaine HCl all show insufficient reliable evidence for the conditions they're commonly used for—including digestive complaints, muscle soreness, and various infections.

Calcium is an exception: it's rated effective for treating low blood calcium and likely effective for osteoporosis, though that's about bone health rather than digestion. Without solid evidence for how these enzymes work in supplement form for typical digestive support, it's hard to say whether this blend lives up to marketing claims.

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.

The enzymes in this product are generally well tolerated at normal doses, but allergic reactions are possible—papain and bromelain can cause itching, hives, and in sensitive people, respiratory symptoms from exposure to airborne dust. Very high doses of papain carry rare risks of severe stomach inflammation or perforation.

Betaine HCl may irritate the stomach and isn't safe for anyone with ulcers or active gastritis. Calcium at recommended doses is safe in pregnancy and breastfeeding, but the safety data on supplemental papain, bromelain, protease, lipase, pepsin, and betaine HCl during pregnancy and breastfeeding is limited or insufficient—talk with your doctor or pharmacist before taking this product if you're pregnant or nursing.

No adverse effects have been reported in adults for lipase, though safety hasn't been thoroughly evaluated.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 4 of the 6 matched ingredients can interact with medications — Papain, Betaine Hydrochloride, Calcium, Bromelain.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications; lithium.
  • For scale: 307 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.

Check before taking if you're on dolutegravir, elvitegravir, or intravenous ceftriaxone (Major interaction with calcium). Also flag any use of other HIV drugs, levothyroxine (thyroid), blood thinners including warfarin, heart medications like sotalol or diltiazem, tetracycline antibiotics, or acid-reducing drugs (H2-blockers, antacids, PPIs).

These Moderate and Minor interactions mean your medications or the supplement could be less effective—your doctor or pharmacist may need to adjust timing or doses.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This is a multi-enzyme supplement aimed at digestive support, but the evidence that these enzymes work as advertised isn't solid. More importantly, it contains calcium and betaine HCl, both of which can interfere with several common medications—including HIV drugs, thyroid meds, blood thinners, and acid-reducing medications.

If you take any prescription medications, run them through the tool on this page, or talk with your doctor or pharmacist before starting. If you're pregnant or nursing, check with your healthcare provider first.

Calcium18 drug types · 168 drugs

Ceftriaxone (Rocephin)

Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction. So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.

Likelihood Probable Evidence D
Dolutegravir (Tivicay)

Calcium seems to reduce levels of dolutegravir.
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation.

Likelihood Probable Evidence B
Elvitegravir (Vitekta)

Calcium seems to reduce levels of elvitegravir.
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation.

Likelihood Probable Evidence B
Aluminum

Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease. However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption.

Likelihood Possible Evidence B
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Calcium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and calcium can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, calcium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Calcium reduces the absorption of bisphosphonates.
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates.

Likelihood Probable Evidence C
Calcipotriene (Dovonex)

Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.

Likelihood Possible Evidence B
Digoxin (Lanoxin)

Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. However, one retrospective analysis of clinical data suggests that intravenous calcium does not increase the risk of dysrhythmias or mortality in patients receiving digoxin.

Likelihood Possible Evidence B
Diltiazem (Cardizem, Others)

Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.

Likelihood Probable Evidence D
Levothyroxine (Synthroid, Others)

Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Advise patients to take levothyroxine and calcium supplements at least 4 hours apart. Calcium reduces levothyroxine absorption, probably by forming insoluble complexes. Calcium carbonate supplements reduce effectiveness of levothyroxine in patients with hypothyroidism.

Likelihood Probable Evidence B
Lithium

Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients. Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.

Likelihood Possible Evidence B
Quinolone Antibiotics

Calcium seems to reduce the absorption of quinolone antibiotics.
Advise patients to take oral quinolones at least 2 hours before or 4-6 hours after calcium supplements or calcium-fortified foods. Taking calcium at the same time as oral quinolones can reduce quinolone absorption. Calcium binds to quinolones in the gut.

Likelihood Probable Evidence B
Raltegravir (Isentress)

Calcium may reduce levels of raltegravir.
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir. However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure.

Likelihood Possible Evidence B
Sotalol (Betapace)

Calcium seems to reduce the absorption of sotalol.
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes.

Likelihood Possible Evidence B
Tetracycline Antibiotics

Calcium seems to reduce the absorption of tetracycline antibiotics.
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut.

Likelihood Probable Evidence C
Thiazide Diuretics

Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Thiazides reduce calcium excretion by the kidneys. Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.

Likelihood Probable Evidence C
Verapamil (Calan, Others)

Theoretically, calcium may reduce the therapeutic effects of verapamil.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.

Likelihood Probable Evidence D
Calcium Channel Blockers

Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects. But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers.

Likelihood Unlikely Evidence D
Calcium full monograph & interactions

Bromelain2 drug types · 141 drugs

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.

Likelihood Possible Evidence B
Bromelain 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

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.

Multi-Enzyme by The Vitamin Shoppe: Common Questions

Does Multi-Enzyme by The Vitamin Shoppe interact with any medications?
Yes. Based on its ingredients, Multi-Enzyme has a known interaction with 307 medications, including 7 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Multi-Enzyme contains 14 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 on levothyroxine for my thyroid?
Not without checking first. Calcium in this product reduces how well your body absorbs levothyroxine, which could make it less effective. Your doctor or pharmacist can advise you on timing—generally you'd take levothyroxine and calcium supplements at least 4 hours apart.
Is this safe if I'm pregnant?
There isn't enough safety data on most of the enzymes in this product during pregnancy. Papain is specifically advised against. Talk with your doctor or pharmacist before taking it—they can help you decide if it's right for you.
Does this product actually help with digestion?
The evidence that digestive enzymes like these improve digestion isn't well established in our data. While calcium is proven effective for certain uses, and the enzymes are generally well tolerated, we can't say the product reliably works for digestive support based on the available evidence.
Can I take this with my acid reflux medication?
Probably not. Betaine HCl in this product works by increasing stomach acid, which directly opposes what acid-reducing drugs (H2-blockers, antacids, PPIs) do. Taking them together could make your reflux medication less effective. Check with your doctor or pharmacist.
What's papain, and why is it in here?
Papain is an enzyme from papaya that breaks down proteins. It's included to support digestion, but the evidence it works for that isn't strong. It can also interact with blood thinners like warfarin, so mention it to your doctor if you're on that medication.
I'm allergic to pineapple—should I avoid this?
This product contains bromelain, an enzyme from pineapple. If you have a pineapple allergy, allergic reactions to bromelain are possible, including itching, hives, and in sensitive people, throat or respiratory symptoms. Skip it and talk to your pharmacist about alternatives.
