HelloPharmacist Scorecard of TheraZinc Zinc Lozenges Cherry Flavor by Quantum Health

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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.
  • “Proprietary Premium Herbal Blend” is a proprietary blend — the label gives one combined amount (20 mg) without saying how much of each component you get.

TheraZinc has four active ingredients. Zinc is the main ingredient — it's the mineral your body needs for immune function, wound healing, and protein processing.

Marshmallow root, slippery elm inner bark, and Eastern larch arabinogalactan are herbal additions; they're included for soothing and supporting throat and digestive comfort, though the evidence for their effectiveness in this lozenge form isn't well established. The product also contains inactive ingredients — sugar, stearic acid, natural cherry flavor, magnesium stearate, and silicon dioxide — which help form and preserve the lozenge.

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: Immune support.
  • We looked for evidence on: Common cold, Coronavirus disease 2019 (COVID-19), Cough, Cold and flu prevention, Immune function.
  • The strongest evidence on file: Zinc is rated "Possibly Effective" for Coronavirus disease 2019 (COVID-19) (Natural Medicines).
  • Also on file: Marshmallow is rated "Insufficient Reliable Evidence To Rate" for ACE inhibitor-induced cough.
  • Also on file: Larch Arabinogalactan is rated "Insufficient Reliable Evidence To Rate" for Common cold.

Zinc itself is proven effective for zinc deficiency and likely effective for Wilson disease. It may be helpful for acne, a skin condition caused by zinc deficiency (acrodermatitis enteropathica), age-related vision loss (AMD), and diabetes, though the evidence in those cases is still developing.

For marshmallow, slippery elm, and larch arabinogalactan, we don't yet have enough reliable evidence to say whether they work for the conditions they're traditionally used for — things like cough, diarrhea, or respiratory infections. If you're taking this lozenge mainly for those effects, the supporting evidence isn't yet solid.

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 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Zinc is well tolerated when you stay below 40 mg a day. At higher doses, it can cause stomach cramps, nausea, diarrhea, a metallic taste, and over the long term, copper deficiency.

The lozenges may cause a metallic taste or mild nausea in some people. Marshmallow and slippery elm are generally well tolerated for short-term use, but long-term safety data are sparse.

Slippery elm can rarely cause contact dermatitis or allergic reactions. There isn't enough safety information to recommend marshmallow or slippery elm during pregnancy or breastfeeding — talk with your doctor or pharmacist if you're pregnant or nursing.

Larch arabinogalactan may cause bloating or gas in some people and shouldn't be used if you're on immunosuppressant drugs without your doctor's approval.

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 4 matched ingredients can interact with medications — Marshmallow, Larch Arabinogalactan, Slippery Elm, Zinc.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; lithium.
  • For scale: 2,122 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 with your pharmacist before using this product if you take quinolone or tetracycline antibiotics, cephalexin, penicillamine, ritonavir, HIV integrase inhibitors, immunosuppressants, lithium, or blood thinners. Zinc interacts with these through chelation — it binds to the drug in your gut and prevents absorption — so spacing doses is critical.

The bottom line

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

This lozenge is a straightforward way to get zinc if you're deficient or at risk for deficiency. If you take antibiotics, blood thinners, HIV medications, lithium, cancer drugs, or immunosuppressants, check your specific medications with your pharmacist before starting — timing matters.

If you're pregnant, nursing, or have long-term health conditions, talk with your pharmacist or doctor first.

Each ingredient & the kinds of drugs it affects

For each ingredient in TheraZinc Zinc Lozenges Cherry Flavor 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.

Marshmallow3 drug types · 2,040 drugs

Lithium

Theoretically, due to potential diuretic effects, marshmallow might reduce excretion and increase levels of lithium.
Marshmallow is thought to have diuretic properties. To avoid lithium toxicity, the dose of lithium might need to be decreased when used with marshmallow.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, marshmallow flower might have antiplatelet effects.
Animal research suggests that marshmallow flower extract has antiplatelet effects. However, the root and leaf of marshmallow, not the flower, are the plant parts most commonly found in dietary supplements. Theoretically, use of marshmallow flower with anticoagulant/antiplatelet drugs can have additive effects, and might increase the risk for bleeding in some patients.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, mucilage in marshmallow might impair absorption of oral drugs.
Marshmallow contains mucilage which can affect oral drug absorption. To avoid changes in absorption, take marshmallow 30-60 minutes after oral medications.

Likelihood Possible Evidence D
Marshmallow full monograph & interactions

Slippery Elm1 drug type · 2,022 drugs

Oral Drugs

Theoretically, slippery elm may slow the absorption and reduce serum levels of oral drugs.
Slippery elm inner bark contains mucilage, which may interfere with the absorption of orally administered drugs.

Likelihood Possible Evidence D
Slippery Elm full monograph & interactions

Eastern Larch Arabinogalactan1 drug type · 121 drugs

Immunosuppressants

Theoretically, larch arabinogalactan might interfere with immunosuppression therapy due to immunostimulant effects. Immunosuppressant drugs include azathioprine (Imuran), basiliximab (Simulect), cyclosporine (Neoral, Sandimmune), daclizumab (Zenapax), muromonab-CD3 (OKT3, Orthoclone OKT3), mycophenolate (CellCept), tacrolimus (FK506, Prograf), sirolimus (Rapamune), prednisone (Deltasone, Orasone), corticosteroids (glucocorticoids), and other drugs.

Likelihood Possible Evidence D
Eastern Larch Arabinogalactan full monograph & interactions

Zinc10 drug types · 67 drugs

Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Theoretically, zinc might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after zinc containing products.

Likelihood Probable Evidence D
Cephalexin (Keflex)

Zinc might decrease cephalexin levels by chelating with cephalexin in the gut and preventing its absorption.
A pharmacokinetic study shows that zinc sulfate 250 mg taken concomitantly with cephalexin 500 mg decreases peak levels of cephalexin by 31% and reduces the exposure to cephalexin by 27%. Also, taking zinc sulfate 3 hours before cephalexin decreases peak levels of cephalexin by 11% and reduces the exposure to cephalexin by 18%. By decreasing cephalexin levels, zinc might increase the risk of treatment failure. This effect does not occur when zinc is taken 3 hours after the cephalexin dose. To avoid an interaction, advise patients take zinc sulfate 3 hours after taking cephalexin.

Likelihood Probable Evidence B
Cisplatin (Platinol-Aq)

Theoretically, zinc might interfere with the therapeutic effects of cisplatin.
Animal research suggests that zinc stimulates tumor cell production of the protein metallothionein, which binds and inactivates cisplatin. It is not known whether zinc supplements or high dietary zinc intake can cause clinically significant interference with cisplatin therapy. Cisplatin might also increase zinc excretion.

Likelihood Possible Evidence D
Integrase Inhibitors

Theoretically, taking zinc along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Zinc is a divalent cation. Pharmacokinetic studies have shown that other divalent cations such as calcium and iron can decrease blood levels of the integrase inhibitor dolutegravir through chelation.

Likelihood Possible Evidence D
Penicillamine (Cuprimine, Depen)

Zinc might reduce the levels and clinical effects of penicillamine.
By forming an insoluble complex with penicillamine, zinc interferes with penicillamine absorption and activity. Zinc supplements reduce the efficacy of low-dose penicillamine (0.5-1 gram/day), but do not seem to affect higher doses (1-2.75 gram/day), provided dosing times are separated. Advise patients to take zinc and penicillamine at least 2 hours apart.

Likelihood Probable Evidence B
Quinolone Antibiotics

Zinc can decrease the levels and clinical effects of quinolones antibiotics.
Quinolones form complexes with zinc in the gastrointestinal tract, reducing absorption of both the quinolone and zinc if taken at the same time. Advise patients to take these drugs at least 2 hours before, or 4-6 hours after, zinc supplements.

Likelihood Probable Evidence B
Ritonavir (Norvir)

Zinc modestly reduces levels of ritonavir.
Clinical research shows that zinc might reduce serum ritonavir levels by chelating with ritonavir in the gut and preventing its absorption. In patients with HIV, ritonavir is taken with atazanavir to prevent the metabolism and increase the effects of atazanavir. A pharmacokinetic study shows that, in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate (Solvazinc tablets) 125 mg as a single dose or as multiple daily doses for 2 weeks reduces plasma levels of ritonavir by about 16%. However, atazanavir levels still remains high enough to prevent HIV virus replication. Therefore, the decrease in ritonavir levels is not likely to be clinically significant.

Likelihood Probable Evidence B
Tetracycline Antibiotics

Zinc might reduce levels of tetracycline antibiotics.
Tetracyclines form complexes with zinc in the gastrointestinal tract, which can reduce absorption of both the tetracycline and zinc when taken at the same time. Taking zinc sulfate 200 mg with tetracycline reduces absorption of the antibiotic by 30% to 40%. Demeclocycline and minocycline cause a similar interaction. However, doxycycline does not seem to interact significantly with zinc. Advise patients to take tetracyclines at least 2 hours before, or 4-6 hours after, zinc supplements to avoid any interactions.

Likelihood Probable Evidence B
Amiloride (Midamor)

Amiloride can modestly reduce zinc excretion and increase zinc levels.
Clinical research shows that amiloride can reduce urinary zinc excretion, especially at doses of 10 mg per day or more. This zinc-sparing effect can help to counteract zinc losses caused by thiazide diuretics, but it is unlikely to cause zinc toxicity at usual amiloride doses. The other potassium-sparing diuretics, spironolactone (Aldactone) and triamterene (Dyrenium), do not seem to have a zinc-sparing effect.

Likelihood Probable Evidence B
Atazanavir (Reyataz)

Zinc modestly reduces levels of atazanavir, although this effect does not seem to be clinically significant.
Clinical research shows that zinc might decrease serum atazanavir levels by chelating with atazanavir in the gut and preventing its absorption. Although a single dose of zinc sulfate (Solvazinc tablets) 125 mg orally does not affect atazanavir concentrations in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate 125 mg daily for 2 weeks reduces plasma levels of atazanavir by about 22% in these patients. However, despite this decrease, atazanavir levels still remain at high enough concentrations for the prevention of HIV virus replication.

TheraZinc Zinc Lozenges Cherry Flavor by Quantum Health: Common Questions

Does TheraZinc Zinc Lozenges Cherry Flavor by Quantum Health interact with any medications?
Yes. Based on its ingredients, TheraZinc Zinc Lozenges Cherry Flavor has a known interaction with 2,121 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
TheraZinc Zinc Lozenges Cherry Flavor contains 4 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 lozenge with my antibiotic?
It depends on which antibiotic. Zinc can form complexes with several antibiotics and reduce how well they work. If you're on a quinolone, tetracycline, or cephalexin, you'll need to space them 2 to 6 hours apart from this lozenge. Check with your pharmacist — they'll tell you which timing works best for your specific drug.
What's the metallic taste I might get?
That's a known side effect of zinc lozenges, especially in the mouth. It's harmless and usually goes away once you swallow. Some people find it stronger than others — it's just your taste buds reacting to the mineral.
Is this lozenge safe during pregnancy?
Zinc in the amounts typically in supplements is safe during pregnancy. But marshmallow and slippery elm don't have enough safety information for pregnancy, so talk with your doctor or pharmacist before using this product if you're pregnant.
Can this help my cold?
This lozenge contains larch arabinogalactan, which is sometimes used for colds. The evidence for it isn't well established yet, so we can't say for sure whether it'll help. Zinc itself is mainly here for general health and deficiency prevention, not to treat a cold.
What if I'm on lithium for my mood disorder?
The marshmallow in this blend might slow how your body clears lithium, which could raise its level in your blood. Talk with your doctor or pharmacist before starting — they may want to monitor your lithium level or adjust your dose.
Can this lozenge slow down my other medications?
Yes. Both marshmallow and slippery elm contain mucilage, which can slow how your gut absorbs oral medications. If you take other drugs, space this lozenge at least 30 to 60 minutes before or after them to be safe.
