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 10 of its 10 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Prosta Glan contains 10 ingredients, of which the active ones are zinc, pumpkin seed extract, stinging nettle root extract, beta-sitosterol, saw palmetto fruit extract, and uva ursi leaf extract. Zinc supports immune function and wound healing.

Pumpkin seed and saw palmetto are traditionally used to support urinary and prostate health. Beta-sitosterol, a plant sterol, may help with cholesterol and prostate function.

Stinging nettle root has been used historically for urinary and joint support. Uva ursi is a urinary tract herb.

The product also contains prostate powder, medium chain triglyceride powder, flower pollen extract, and phytopin, along with inactive ingredients: gelatin, vegetable lubricant, and silica.

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: prostate gland health and function.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Erectile dysfunction (ED), Urinary flow, Prostate inflammation.
  • The strongest evidence on file: Beta-sitosterol 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's ingredients is mixed. Zinc is effective for zinc deficiency and likely effective for Wilson disease, though it's only possibly effective for acne and other conditions.

Beta-sitosterol is likely effective for benign prostatic hyperplasia (enlarged prostate), while saw palmetto and pumpkin seed extract are rated possibly effective for BPH. Stinging nettle is possibly effective for diabetes and for hay fever.

For several uses—like stinging nettle for anemia or asthma, saw palmetto for hair loss, and uva ursi for urinary tract infections—we have insufficient evidence to establish how well they work. We hold no effectiveness data for prostate powder, medium chain triglyceride powder, flower pollen extract, or phytopin.

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.

Zinc is well tolerated at recommended doses (below 40 mg daily for adults) but high doses can cause abdominal cramps, nausea, diarrhea, or metallic taste; long-term high doses raise the risk of copper deficiency. Pumpkin seed extract is generally safe when used as a food or concentrated supplement, though abdominal discomfort and diarrhea can occur—and case reports link wild pumpkin with high cucurbitacin to hair loss and severe nausea.

Stinging nettle is generally well tolerated but should be avoided in pregnancy due to traditional uterine concerns; safety during breastfeeding isn't established. Beta-sitosterol is generally well tolerated short-term but should be avoided in pregnancy and breastfeeding due to insufficient data; it can cause constipation, diarrhea, gas, or nausea.

Saw palmetto is likely unsafe in pregnancy and safety during breastfeeding is not established; common side effects are mild but include abdominal pain, diarrhea, nausea, and decreased libido. Uva ursi is well tolerated short-term but can be toxic at high doses (20+ grams of dried herb); avoid it in pregnancy and breastfeeding.

We hold no pregnancy/breastfeeding data for pumpkin seed, prostate powder, medium chain triglyceride powder, flower pollen extract, or phytopin.

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 — Uva Ursi, 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: 1,063 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, check whether you use quinolone antibiotics, cephalexin, tetracyclines, or penicillamine—zinc will reduce their absorption and you'll need to separate dosing by hours. If you take blood thinners (warfarin) or antiplatelet drugs, saw palmetto and stinging nettle may interfere.

Blood sugar medications and lithium both require caution with multiple ingredients here. Estrogen or contraceptive drugs may be less effective with saw palmetto.

If you take HIV medications (ritonavir, integrase inhibitors, bictegravir combinations), liver enzyme substrates, or glucuronidated drugs, uva ursi or zinc may alter their levels. Discuss these with your pharmacist before you start.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Prosta Glan is aimed at men's urinary and prostate health, with some ingredients showing modest evidence. Before you start, check your medications carefully—zinc, stinging nettle, saw palmetto, and uva ursi all interact with prescription drugs, and lithium users should be especially cautious.

If you're pregnant, breastfeeding, taking blood thinners, or managing blood sugar, talk with your pharmacist first.

Uva Ursi leaf extract6 drug types · 803 drugs

Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, uva ursi may decrease the metabolism of CYP2C19 substrates.
In vitro, uva ursi appears to inhibit cytochrome CYP2C19. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, uva ursi may decrease the metabolism of CYP3A4 substrates.
In vitro, uva ursi appears to inhibit CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, uva ursi may increase levels of drugs metabolized by glucuronidation.
In vitro, uva ursi extract appears to strongly inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1). However, uva ursi extract does not appear to inhibit UGT1A1 in animal models. This effect has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, uva ursi may increase lithium levels, necessitating a decrease in dose.
Uva ursi may have diuretic properties. Diuretics may increase lithium reabsorption with sodium in the proximal tubule of the kidney. Theoretically, uva ursi might reduce excretion and increase levels of lithium.

Likelihood Probable Evidence D
Urinary Acidifying Agents

Effects of uva ursi in the urinary tract may be reduced by urinary acidifying agents.
Uva ursi seems to work best in alkaline urine. Theoretically, taking uva ursi with medications known to acidify the urine may decrease any effects of uva ursi on the urinary tract.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, uva ursi may alter the levels of drugs transported by P-glycoprotein.
In vitro, uva ursi appears to inhibit the multi-drug transporter protein, P-glycoprotein. This effect has not been reported in humans.

Saw Palmetto fruit 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
Saw Palmetto fruit extract full monograph & interactions

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
Stinging Nettle root extract 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.

Likelihood Probable Evidence B

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.

Prosta Glan by Progressive Professional from Progressive Laboratories: Common Questions

Does Prosta Glan by Progressive Professional from Progressive Laboratories interact with any medications?
Yes. Based on its ingredients, Prosta Glan has a known interaction with 1,062 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Prosta Glan contains 10 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 if I take warfarin (Coumadin)?
No. Stinging nettle contains vitamin K, which can reduce warfarin's blood-thinning effect, and saw palmetto may increase your bleeding risk. Talk to your pharmacist or doctor before taking this product.
Can I take this if I'm on a blood sugar medication?
Not without checking first. Stinging nettle may lower blood glucose and could work additively with diabetes drugs, creating low blood sugar (hypoglycemia). Your doctor may need to adjust your medication dose.
What should I know about zinc absorption with antibiotics?
Zinc can bind with certain antibiotics in your stomach and block absorption of both. If you take quinolone, tetracycline, or cephalexin antibiotics, separate them from this product by at least 2–6 hours, depending on the antibiotic. Your pharmacist can advise on exact timing.
Is this safe during pregnancy?
No. Saw palmetto and stinging nettle should be avoided in pregnancy due to hormone effects and lack of safety data. Beta-sitosterol and uva ursi also lack sufficient safety data in pregnancy. Talk with your doctor before use.
Can I take this while breastfeeding?
Safety data isn't available for most ingredients in this product during breastfeeding, including stinging nettle, saw palmetto, beta-sitosterol, and uva ursi. Check with your doctor or pharmacist before use.
What side effects might I notice from the zinc?
At recommended doses, zinc may cause abdominal cramps, nausea, diarrhea, or a metallic taste. These are usually mild and dose-related. If you exceed 40 mg daily long-term, there's a risk of copper deficiency.
