HelloPharmacist Scorecard of Prostate+ by Wonder Laboratories
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.
What’s inside
Full disclosure
Prostate+ contains 8 ingredients total. The active components are vitamin B6, L-alanine, calcium, L-glycine, L-glutamic acid, zinc, prostate concentrate, and pumpkin concentrate.
These are combined with inactive ingredients — vegetable cellulose, vegetable stearic acid, silica, vanillin, and vegetable magnesium stearate — which serve as the tablet's structure and binding. Vitamin B6 supports nervous system function and amino acid metabolism.
Calcium is a mineral essential for bone health. L-Alanine and L-glycine are amino acids.
Zinc is a mineral involved in immune function and wound healing. Prostate concentrate and pumpkin concentrate are plant-based ingredients included for prostate support.
Does it work?
Moderate evidence
The evidence picture here is mixed. Vitamin B6 is effective for sideroblastic anemia and vitamin B6 deficiency itself, and likely effective for high homocysteine levels; it's possibly effective for pregnancy-related nausea.
Calcium is effective for low blood calcium and certain electrolyte imbalances, and likely effective for bone loss. Zinc is effective for zinc deficiency and likely effective for Wilson disease; it's possibly effective for acne and age-related vision loss.
For the ingredients most relevant to prostate health — L-alanine, L-glycine, and pumpkin concentrate — the evidence we hold shows insufficient data for most uses. Pumpkin concentrate is possibly effective for benign prostate enlargement (BPH), but we don't have established evidence for L-alanine or L-glycine in that area.
We couldn't assess L-glutamic acid or prostate concentrate from our data.
How safe is it?
Well-documented data
Vitamin B6 is generally well tolerated at doses under 100 mg daily, though high doses taken over time can damage nerves (sensory neuropathy), especially above 1000 mg daily. Common side effects at any dose include headache, heartburn, and nausea.
Calcium is well tolerated at recommended amounts; the most common effects are mild digestive — constipation, gas, or upset stomach. L-Glycine is generally well tolerated at typical doses, though long-term safety data are limited; rare effects include mild sedation and gastrointestinal discomfort.
Zinc is well tolerated below 40 mg daily, with nausea, diarrhea, and a metallic taste most common at higher doses. Pumpkin concentrate from food is generally well tolerated; concentrated supplements may cause abdominal discomfort, diarrhea, or nausea.
Pregnancy and breastfeeding data are limited for most of these ingredients — vitamin B6 is likely safe in pregnancy and lactation at standard doses, calcium is likely safe in both, and L-alanine is likely safe. For L-glycine, zinc, pumpkin concentrate, and prostate concentrate, pregnancy and lactation safety data aren't on file or are incomplete.
If you're pregnant, nursing, or planning to be, talk with your doctor or pharmacist about whether this product is right for you.
Meds to double-check
Major interaction found
Before taking Prostate+, check with your doctor or pharmacist if you take any HIV integrase inhibitors (dolutegravir, elvitegravir, bictegravir), the antibiotic ceftriaxone, thyroid medication (levothyroxine), blood pressure drugs (especially diltiazem, sotalol, or antihypertensives generally), the heart rhythm drug amiodarone, seizure medications (phenobarbital, phenytoin), antibiotics (quinolones, tetracyclines, cephalexin), the antipsychotic clozapine, lithium, ritonavir, or cisplatin. Timing adjustments or dose changes may be needed for several of these.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Prostate+ is built around ingredients with some evidence for general nutritional support and one (pumpkin) with possibly useful data for prostate health. It carries several notable medication interactions, especially with HIV drugs, antibiotics, thyroid medication, and blood pressure medications.

Prostate+ by Wonder Laboratories Drug Interactions
HelloPharmacist Interaction Report
Prostate+ by Wonder Laboratories interacts with medications through its vitamin B6, calcium, L-glycine, zinc, and pumpkin concentrate content.
The most serious interaction is calcium's Major-severity effect on HIV integrase inhibitors like dolutegravir and elvitegravir — calcium can reduce blood levels of these drugs by up to 40%, potentially compromising HIV treatment. It also poses a Major risk with the antibiotic ceftriaxone when given intravenously, where the combination can cause dangerous precipitation in the lungs and kidneys.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 interacts with blood pressure medications (antihypertensives) and certain seizure drugs. High doses may reduce effectiveness of phenobarbital and phenytoin by speeding up how your liver clears them, and may theoretically intensify sun sensitivity from the heart medication amiodarone.
Calcium reduces absorption of the thyroid drug levothyroxine and the blood pressure medication sotalol — timing your doses several hours apart can help. Zinc binds to several antibiotics (quinolones, tetracyclines, cephalexin) and the HIV drug ritonavir, reducing how much your body absorbs; it may also theoretically interfere with the cancer drug cisplatin and other HIV integrase inhibitors.
L-Glycine may theoretically reduce the effectiveness of the antipsychotic clozapine. Pumpkin concentrate might increase lithium levels by reducing its excretion, potentially raising lithium to unsafe concentrations.
L-Glutamic acid and prostate concentrate — we couldn't check these ingredients. Altogether, these interactions span 316 individual medications.

For each ingredient in Prostate+ 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.
Vitamin B6
Amiodarone (Cordarone)
Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.
Antihypertensive Drugs
Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.
Phenobarbital (Luminal)
High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.
Phenytoin (Dilantin)
High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.
Levodopa
Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.
Calcium
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Zinc
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
L-Glycine
Clozapine (Clozaril)
Theoretically, glycine might decrease the effectiveness of clozapine.
One small clinical study in patients with schizophrenia shows that adding glycine to clozapine therapy worsens symptoms of schizophrenia when compared with clozapine alone. The mechanism of this interaction is unclear.
Pumpkin concentrate
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.
