What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 11 of its 11 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Zyme-Aid contains 11 active ingredients: calcium for bone health and other body functions; bromelain (a pineapple enzyme); pepsin and acid protease (digestive enzymes); papain (a papaya enzyme); lactase (for milk sugar digestion); plus cellulase, alpha-amylase, betaine, ox bile extract, and pancreatin extract 3X. Together, these work as digestive aids.

The product also contains inactive ingredients including lactose, cellulose, stearic acid, silica, magnesium stearate, vanilla, and a vegetable glaze coating.

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: Digestive enzyme support.
  • We looked for evidence on: Dyspepsia, Exercise-induced muscle damage, Exercise-induced muscle soreness, Lactose intolerance, Postoperative pain, Postoperative swelling — and 4 related terms.
  • The strongest evidence on file: Lactase is rated "Effective" for Lactose intolerance (Natural Medicines).
  • Also on file: Calcium is rated "Effective" for Dyspepsia.
  • Also on file: Papain is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness, Wound healing.

Calcium in this product is effective for kidney failure, dyspepsia (indigestion), low blood calcium, high potassium, and likely effective for osteoporosis. Lactase is effective for lactose intolerance.

For the other active ingredients — bromelain, pepsin, papain, and the remaining enzymes — the evidence for their specific uses is insufficient or not established in the data we hold. The product's overall digestive-aid claim rests primarily on calcium and lactase.

The evidence, ingredient by ingredient Calcium Bromelain Proteolytic Enzymes (proteases) Papain Lactase

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Calcium is generally well tolerated at recommended doses, though high doses can cause problems; common side effects include belching, constipation, diarrhea, flatulence, and stomach upset. There is some concern that very high calcium intake (over 1500–2000 mg daily) may be linked to increased prostate cancer risk and cardiovascular risk, though these findings remain debated.

Bromelain is well tolerated short-term but evidence on long-term use is limited; it can cause diarrhea, flatulence, gastric upset, and headache. Pepsin and acid protease may cause digestive upset or allergic reactions.

Papain may irritate the digestive tract or trigger allergic reactions (itching, hives, rash) in sensitive individuals. During pregnancy, adequate calcium is important and recommended amounts are safe; bromelain should be avoided due to insufficient safety data.

During breastfeeding, calcium and lactase are generally acceptable at recommended doses, but bromelain, pepsin, acid protease, and papain should be avoided or discussed with your provider due to limited safety information.

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?
  • 3 of the 5 matched ingredients can interact with medications — Papain, 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: 285 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 Zyme-Aid, double-check these medication types with your pharmacist: HIV integrase inhibitors (dolutegravir, elvitegravir) — calcium can lower their levels by a large amount; the antibiotic ceftriaxone given intravenously; blood thinners (warfarin and other anticoagulants or antiplatelet drugs); thyroid medication (levothyroxine); heart rhythm drugs like sotalol; and blood pressure medications like diltiazem. These are Major and Moderate interactions.

Each ingredient & the kinds of drugs it affects

For each ingredient in Zyme-Aid 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.

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

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.

Zyme-Aid by Country Life: Common Questions

Does Zyme-Aid by Country Life interact with any medications?
Yes. Based on its ingredients, Zyme-Aid has a known interaction with 285 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?
Zyme-Aid contains 11 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.
Is this product safe to take if I'm pregnant?
Calcium at recommended amounts is considered safe and important during pregnancy. However, bromelain should be avoided — there isn't enough safety data. For the other ingredients in this product, there isn't enough information on file about their use in pregnancy. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy.
What are the most common side effects I might experience?
From calcium: belching, constipation, diarrhea, flatulence, and stomach upset. From bromelain: diarrhea, flatulence, gastric upset, and headache. From pepsin and papain: some people may experience digestive upset or allergic reactions like itching or hives.
Does this product work for upset stomach?
Calcium in Zyme-Aid is effective for dyspepsia (indigestion). The other enzymes and ingredients are meant to support digestion, but we don't have strong evidence for their specific uses in our data.
Can I take this if I'm on warfarin?
No — this product contains papain, which may increase warfarin's blood-thinning effects and raise your bleeding risk. Also, the calcium could theoretically add to that risk. Do not take this product if you're on warfarin without talking to your pharmacist or doctor first.
Is lactose in this product a problem if I'm lactose intolerant?
The product does contain lactose as an inactive ingredient. However, it also contains lactase, which breaks down milk sugar. If you're lactose intolerant, start with a small dose and see how you tolerate it. If you have severe intolerance, ask your pharmacist if there's a lactose-free alternative.
Can I take this with my thyroid medication?
The calcium in this product can reduce how much thyroid medication (levothyroxine) your body absorbs. You'd need to space them at least 4 hours apart. Check with your pharmacist to work out a timing schedule that protects your thyroid treatment.
