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 6 active ingredients.
  • “Nourishing Food Blend” is a proprietary blend — the label gives one combined amount (26 mg) without saying how much of each component you get.

This product contains 6 active ingredients: beet, parsley, carrot, broccoli, spinach, and zinc, all organized under a "Nourishing Food Blend" framework. Each ingredient brings a different nutrient profile—beet and spinach provide nitrates and minerals, broccoli and carrot offer glucosinolates and vitamin A, parsley adds vitamin K, and zinc is a standalone mineral.

The inactive ingredients are brown rice, autolyzed yeast extract, rice protein, yeast, silicon dioxide, microcrystalline cellulose, stearic acid, and hypromellose (a capsule material).

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 health.
  • We looked for evidence on: Acne, Acrodermatitis enteropathica, Atopic dermatitis (eczema), Bronchiolitis, Canker sores, Child growth — and 4 related terms.
  • The strongest evidence on file: Zinc is rated "Possibly Effective" for Acne (Natural Medicines).
  • Also on file: Zinc is rated "Possibly Effective" for Acrodermatitis enteropathica, Diaper rash, Child growth.
  • Also on file: Zinc is rated "Possibly Ineffective" for Cystic fibrosis.

The evidence for these ingredients is mixed and often limited. Zinc is rated Effective for zinc deficiency and Likely Effective for Wilson disease; it's Possibly Effective for acne, age-related macular degeneration, and diabetes.

Beet and broccoli are Possibly Effective for athletic performance and colorectal cancer, respectively, though most other claims carry Insufficient Reliable Evidence. Carrot is Possibly Effective for vitamin A deficiency but insufficient evidence for cancer prevention.

Parsley and spinach lack established evidence for the conditions they're studied in—the data we hold rates them Insufficient Reliable Evidence To Rate across their uses. If you're taking this for a specific health goal, check whether the ingredient is actually backed by evidence for that use.

The evidence, ingredient by ingredient Beet Parsley Carrot Broccoli Spinach Zinc

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.

As foods, these ingredients are generally well tolerated by most adults. However, this is a concentrated supplement, not whole food, and the safety data on concentrated doses is thinner—especially for beet, parsley, and broccoli extracts.

Beet and spinach may cause red or black stools (harmless) but can rarely cause low calcium or kidney damage at very high doses. Parsley in large amounts (over 10 grams of its active constituents) poses serious risks including hemolytic anemia and low platelet counts; anaphylaxis has been reported.

Broccoli extracts can cause loose stools, diarrhea, and cramping, especially at high doses. Zinc is well tolerated below 40 mg per day but causes nausea, diarrhea, and metallic taste at higher doses; prolonged high-dose zinc may deplete copper, risking anemia.

Carrot and spinach carry no pregnancy/breastfeeding safety concerns when consumed as foods; data on their concentrated forms during pregnancy or breastfeeding is limited for carrot, and no data is on file for parsley or beet in these periods.

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?
  • 5 of the 6 matched ingredients can interact with medications — Beet, Spinach, Parsley, Zinc, Broccoli.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,068 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 this product, double-check with your pharmacist if you use anticoagulants or antiplatelet drugs (parsley increases bleeding risk), quinolone or tetracycline antibiotics, cephalexin, penicillamine, ritonavir, HIV integrase inhibitors, or cisplatin (zinc and other ingredients reduce absorption or effectiveness). Also check if you take warfarin, other blood thinners, or diabetes medications—parsley and spinach contain vitamin K or lower blood sugar, respectively, and may interfere.

Each ingredient & the kinds of drugs it affects

For each ingredient in Zinc 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.

Beet3 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 full monograph & interactions

Parsley8 drug types · 443 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, parsley might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Animal research suggests that parsley has antiplatelet effects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, parsley might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that parsley might decrease blood glucose. Monitor blood glucose levels closely. Dose adjustments might be necessary.

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

Theoretically, parsley might increase serum levels of CYP1A2 substrates.
Laboratory research suggests that parsley can inhibit CYP1A2.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, parsley might enhance or interfere with the effects of diuretic drugs.
Animal research suggests that parsley seed extract increases urine elimination. Parsley leaf and root might also interfere with diuretic therapy due their purported aquaretic effects.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, parsley might increase the duration of pentobarbital effects.
Animal research suggests that parsley juice prolongs the action of pentobarbital, perhaps by decreasing cytochrome P450 levels. It is not known if this occurs in humans or if this applies to other barbiturates or sedatives.

Likelihood Possible Evidence D
Sirolimus (Rapamune)

Theoretically, large quantities of parsley might increase sirolimus levels.
In one case report, an adult female with a history of kidney transplant presented with elevated blood sirolimus levels, approximately 4-7 times greater than previous measures, after daily consumption of a juice containing approximately 30 grams of parsley for 7 days. Sirolimus levels returned to normal a week after the parsley juice was discontinued.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, large amounts of parsley leaf and root might decrease the effects of warfarin.
Parlsey contains vitamin K.

Likelihood Possible Evidence D
Aspirin

Theoretically, aspirin might increase the severity of allergic reactions to parsley.
In one case, severe urticaria and swelling were reported after taking aspirin with parsley in an individual with a known mild parsley allergy.

Likelihood Unlikely Evidence D
Parsley full monograph & interactions

Broccoli2 drug types · 187 drugs

Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP1A2.
Pharmacokinetic research in humans shows that eating 500 grams of fresh broccoli daily for 6-12 days can increase CYP1A2 activity by 10% to 200%. Induction of CYP1A2 activity by broccoli is attributed to its glucosinolate constituents.

Likelihood Possible Evidence B
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP2A6.
Pharmacokinetic research in humans shows that eating 500 grams of broccoli daily for 6 days increases CYP2A6 activity by 135% to 550%. Induction of CYP2A6 activity is attributed to its glucosinolate constituents.

Likelihood Possible Evidence B
Broccoli full monograph & interactions

Spinach2 drug types · 88 drugs

Antidiabetes Drugs

There are claims that spinach leaves have hypoglycemic effects. Evidence from clinical research suggests that consumption of a spinach-rich meal reduces post-meal blood glucose levels. Theoretically, spinach might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. Monitor blood glucose levels closely. Dose adjustments might be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Spinach contains vitamin K, which can interfere with the activity of warfarin.
In human research, although eating spinach with one meal does not result in coagulation test results outside the therapeutic range, daily consumption for one week necessitates dose adjustment of warfarin. Individuals using anticoagulants should consume a consistent daily amount of spinach to maintain the effect of anticoagulant therapy.

Likelihood Possible Evidence D
Spinach 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.

Zinc by Innate Response Formulas: Common Questions

Does Zinc by Innate Response Formulas interact with any medications?
Yes. Based on its ingredients, Zinc has a known interaction with 1,067 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Zinc contains 6 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.
Does this product work for general wellness?
The ingredients have some evidence for specific uses—zinc for deficiency, beet for athletic performance, broccoli for colorectal cancer—but most claims in the data we hold are rated Insufficient Evidence. If you're taking it for general nutrition, that's different from taking it to treat a health condition; talk with your pharmacist about what you're hoping it will do.
Can I take this while pregnant or breastfeeding?
Spinach, broccoli, and carrot as foods are considered safe during pregnancy and breastfeeding. However, data is not on file for concentrated parsley, beet, or the full supplement formula during these periods. If you're pregnant or breastfeeding, talk with your doctor or pharmacist before taking this product.
What does zinc do in this formula?
Zinc is an essential mineral important for immune function, wound healing, and many enzyme reactions in your body. In this product it's meant to fill dietary gaps, though at a dose we can't verify from the label; it's also rated Effective for treating zinc deficiency if that applies to you.
Why is parsley in a supplement—isn't it just an herb?
Parsley is traditionally used as a culinary herb, but this product includes it in a concentrated form for its potential nutrient and phytochemical content. As a food parsley is safe, but concentrated supplements lack strong safety data, so use caution and check with your doctor if you're on any medications.
Will this cause red urine or stool?
Yes—beet is known to cause red or sometimes black stools and red urine in some people. This is harmless and should resolve once you stop taking the product. If you see black stools and are on a blood thinner, mention it to your pharmacist to rule out bleeding.
How should I space this away from my medications?
If you take antibiotics (especially quinolones or tetracyclines) or cephalexin, take zinc at least 2–6 hours before or after your antibiotic. For other medications, your pharmacist can advise spacing based on your specific drugs. Use the interaction checker on this page with your exact medication list.
