HelloPharmacist Scorecard of Enzyme Tabs by Wonder 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
Partial disclosure
Enzyme Tabs contains 7 active ingredients — a blend of digestive enzymes and minerals designed to support digestion. Papain is an enzyme from papaya; lipase, protease, amylase, and cellulase are enzymes that break down fats, proteins, carbohydrates, and fiber respectively.
Pancreatin is a combination enzyme extract. Calcium provides a mineral cofactor.
Bile extract supports fat digestion. The product also contains inactive ingredients: vegetable stearic acid, vegetable cellulose, silica, and vanillin (a flavoring).
Does it work?
Strong evidence
The evidence for most ingredients in this product hasn't been firmly established. Papain's effectiveness for cancer, dental decay, radiation damage to skin, muscle soreness, shingles, and parasite infection all lack reliable evidence in the data we hold.
Lipase's use for inflammatory bowel disease, indigestion, and other digestive conditions similarly shows insufficient evidence. Protease's effectiveness isn't rated in our data.
Calcium, however, is well-supported: it's effective for low blood calcium levels and high potassium levels, likely effective for bone loss, and effective for treating indigestion. If you're considering this product mainly for its enzyme content, talk with your doctor about whether the evidence supports its use for your particular concern.
How safe is it?
Well-documented data
Papain is generally tolerated when eaten as food, but supplements may irritate your digestive tract or trigger allergic reactions in sensitive people — symptoms can include itchy eyes, runny nose, sneezing, stomach cramps, sweating, and diarrhea. High doses may cause severe inflammation or even a hole in the esophagus, though this is rare.
Concentrated papain and unripe papaya products should be avoided in pregnancy due to safety concerns. Not enough data exists to safely recommend papain while breastfeeding.
Lipase and protease are generally well tolerated, though protease may cause digestive upset or allergic reactions. Calcium at recommended amounts is generally safe; it may cause belching, constipation, diarrhea, gas, or stomach upset.
Very high calcium doses raise rare concerns about kidney stones and calciphylaxis.
Meds to double-check
Major interaction found
Stop and check with your doctor or pharmacist before taking Enzyme Tabs if you're on dolutegravir or elvitegravir (HIV medications), ceftriaxone (an antibiotic given by IV), raltegravir (another HIV medication), levothyroxine (thyroid hormone), sotalol (heart rhythm medication), calcipotriene (psoriasis treatment), diltiazem (heart medication), or warfarin (blood thinner). These medications require careful spacing or monitoring with calcium and papain.
The bottom line
Scorecard at a glancePartially disclosed formula with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
Enzyme Tabs may help with digestion if you have low stomach acid or enzyme deficiency, but the evidence for most of its enzymes isn't strong. The bigger concern is calcium's interactions with HIV medications, some antibiotics, blood thinners, and thyroid and heart drugs — if you take any of those, you need to discuss this product with your doctor or pharmacist before starting.
If you have a history of papain or enzyme allergies, or if you're pregnant or breastfeeding, check with your healthcare provider first.

Enzyme Tabs by Wonder Laboratories Drug Interactions
HelloPharmacist Interaction Report
Enzyme Tabs by Wonder Laboratories does interact with medications, primarily through its calcium and papain content.
The most serious interaction involves calcium with HIV integrase inhibitors and a cephalosporin antibiotic. Calcium can significantly reduce blood levels of dolutegravir and elvitegravir — HIV medications that need to stay at therapeutic levels — and it can cause dangerous precipitation when mixed intravenously with ceftriaxone, an infection-fighting antibiotic.
Read the full breakdown — every affected drug type, severity by severity
Calcium in this product also moderately reduces the effectiveness of several other medications: the heart rhythm drug sotalol, the thyroid hormone levothyroxine, and the calcium-regulating medication calcipotriene used for psoriasis. Calcium may also reduce absorption of the HIV integrase inhibitor raltegravir and may lower the effect of the heart medication diltiazem.
Papain adds a separate moderate interaction with warfarin, a blood thinner — it may increase warfarin's effects and bleeding risk.
Lipase and protease have no documented interactions in our data. We could not check cellulase, amylase, or bile extract — we hold no interaction data for these ingredients.
Altogether, these interactions span 170 individual medications.
Before starting Enzyme Tabs, check with your doctor or pharmacist about any HIV medications, antibiotics, blood thinners, thyroid hormones, heart medications, or psoriasis treatments you're taking.

For each ingredient in Enzyme Tabs 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.
Calcium
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Papain
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.
