HelloPharmacist Scorecard of NZ-Prostate Max by Everyday 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

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 6 of its 6 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

NZ-Prostate Max contains six active ingredients, each chosen for urinary or prostate health. Pumpkin seed extract is possibly effective for benign prostatic hyperplasia (BPH).

Zinc is a mineral needed for immunity and wound healing and is effective for zinc deficiency. Saw palmetto berry extract is possibly ineffective for BPH based on current evidence.

Stinging nettle root extract is possibly effective for diabetes and may support urinary function. Pygeum bark extract is likely effective for benign prostatic hyperplasia.

Lycopene is a carotenoid (plant pigment) possibly effective for prostate cancer. The product also contains inactive ingredients—gelatin and rice flour—which act as a capsule and filler.

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: Support optimal prostate health.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Erectile dysfunction (ED), Prostate enlargement, Lower urinary tract symptoms, Male urinary health.
  • The strongest evidence on file: Pygeum is rated "Likely Effective" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Pumpkin is rated "Possibly Effective" for Benign prostatic hyperplasia (BPH).
  • Also on file: Saw Palmetto is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH).

The evidence for this product is mixed. Pygeum bark is likely effective for BPH, and both pumpkin and stinging nettle root are possibly effective for BPH — though saw palmetto appears possibly ineffective for that condition based on current research.

Lycopene is possibly effective for prostate cancer specifically. Zinc is effective for zinc deficiency but has only possibly effective evidence for diabetes.

For most of the other uses these ingredients are studied for — hair loss, hay fever, anemia, asthma, and others — we don't have reliable evidence to rate them.

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.

Pumpkin and saw palmetto are generally well tolerated, though pumpkin may cause abdominal discomfort, diarrhea, nausea, or vomiting, and rare cases of hair loss or anaphylaxis have been reported. Zinc is well tolerated below 40 mg daily but can cause metallic taste, nausea, diarrhea, and abdominal cramps at higher doses; long-term high-dose use may deplete copper.

Saw palmetto may cause abdominal pain, decreased libido, diarrhea, dizziness, headache, and rarely serious cardiac effects. Stinging nettle is generally well tolerated but has caused liver injury in rare case reports.

Pygeum is generally well tolerated short-term. Lycopene may cause diarrhea, bloating, nausea, or vomiting.

For pregnancy: pumpkin food is fine but concentrated supplements lack safety data. Saw palmetto is likely unsafe in pregnancy.

Stinging nettle is likely unsafe in pregnancy. Pygeum and lycopene have no established safe use or insufficient data in pregnancy — talk with your doctor.

For breastfeeding: safety data are limited or absent for pumpkin concentrates, saw palmetto, stinging nettle, and lycopene supplements — discuss with your pharmacist or doctor before use.

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 — Lycopene, Stinging Nettle, Pumpkin, Saw Palmetto, Zinc.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 401 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 you take this product, check with your doctor or pharmacist if you're on lithium (pumpkin and stinging nettle may increase levels), blood thinners or antiplatelet drugs like warfarin or aspirin (saw palmetto and lycopene may increase bleeding risk; stinging nettle interferes with warfarin), diabetes medications (stinging nettle may have additive effects), diuretics (pumpkin and stinging nettle may have additive effects), estrogens or contraceptives (saw palmetto may reduce effectiveness), antibiotics including quinolones, tetracyclines, or cephalexin (zinc reduces absorption), HIV medications including ritonavir, integrase inhibitors, or Biktarvy (zinc may lower levels), or cancer drugs like cisplatin (zinc may interfere). These are moderate-severity concerns.

For each ingredient in NZ-Prostate Max 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.

Saw Palmetto Berry Extract3 drug types · 174 drugs

Anticoagulant/Antiplatelet Drugs

Saw palmetto might increase the risk of bleeding with anticoagulant or antiplatelet drugs.
Saw palmetto is reported to prolong bleeding time. Theoretically, it might increase the risk of bleeding when used concomitantly with anticoagulant or antiplatelet drugs.

Likelihood Possible Evidence D
Contraceptive Drugs

Saw palmetto might reduce the effectiveness of contraceptive drugs.
Saw palmetto might have antiestrogenic effects. Theoretically, it might interfere with contraceptive drugs taken concomitantly.

Likelihood Possible Evidence B
Estrogens

Saw palmetto might reduce the effectiveness of estrogens.
Saw palmetto might have antiestrogenic effects. Theoretically, it might interfere with estrogens taken concomitantly.

Likelihood Possible Evidence B

Stinging Nettle Root Extract4 drug types · 164 drugs

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

Likelihood Possible Evidence D

Lycopene1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking lycopene with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
In vitro research shows that lycopene has antiplatelet effects.

Likelihood Possible Evidence D

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.

Likelihood Probable Evidence B

Pumpkin1 drug type · 1 drug

Lithium

Pumpkin might reduce excretion and increase levels of lithium.
Pumpkin is thought to have diuretic properties. Theoretically, this might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

NZ-Prostate Max by Everyday Health: Common Questions

Does NZ-Prostate Max by Everyday Health interact with any medications?
Yes. Based on its ingredients, NZ-Prostate Max has a known interaction with 401 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
NZ-Prostate Max 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.
Will this product affect my blood thinner?
Possibly. Saw palmetto and lycopene theoretically increase bleeding risk, and stinging nettle contains vitamin K which may interfere with warfarin. Talk with your doctor or pharmacist before taking it alongside any blood thinner or antiplatelet drug — they can tell you if it's safe for you or if timing adjustments help.
What's actually in this for prostate health?
Pygeum bark is likely effective for BPH. Pumpkin seed extract and stinging nettle root are possibly effective for it. Saw palmetto is possibly ineffective based on current evidence, though it's a common prostate ingredient. Lycopene is possibly effective specifically for prostate cancer risk. Together they cover a few angles, though pygeum is the strongest evidence-backed one here.
Can I take this if I'm on an antibiotic?
The zinc in this product can reduce absorption of many antibiotics — especially quinolones, tetracyclines, and cephalexin — if taken at the same time. You'd need to space them at least 2–6 hours apart. Check with your pharmacist about which antibiotic you're on and the best timing.
What are the most common side effects?
Most adverse effects are mild: pumpkin and zinc may cause abdominal discomfort, diarrhea, nausea, or vomiting. Saw palmetto may cause headache, dizziness, or decreased libido. Lycopene may cause bloating or diarrhea. Serious side effects are rare but have been reported.
Is this safe in pregnancy?
There isn't enough safety data to know either way for most of these ingredients in pregnancy. Saw palmetto and stinging nettle are considered likely unsafe. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy — they can weigh the risks and benefits for your situation.
Can I take this with my diabetes medication?
Stinging nettle may lower blood sugar and theoretically have additive effects with diabetes drugs. This doesn't automatically mean you can't take it, but your doctor or pharmacist should know you're adding it so they can monitor your blood sugar or adjust your medication dose if needed.
