HelloPharmacist Scorecard of TestosterZone by Progressive Professional from Progressive 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

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 0 of its 4 active ingredients.
  • “Testosterzone Proprietary Blend” is a proprietary blend — the label gives one combined amount (850 mg) without saying how much of each component you get.

TestosterZone contains four active ingredients. Astaxanthin is a carotenoid (a plant pigment) studied for age-related eye health and skin aging, though evidence is currently insufficient.

Phosphatidylserine is a fatty compound found in cell membranes, possibly effective for age-related memory decline and Alzheimer disease. KSM-66 ashwagandha extract is an adaptogenic herb possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder.

Pomella is a pomegranate extract possibly effective for high blood pressure but possibly ineffective for high cholesterol and diabetes. The product also contains inactive ingredients (microcrystalline cellulose, hydroxypropyl methylcellulose, and silicon dioxide) as capsule material and binders.

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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Hypertension — rated "Possibly Effective" (Pomegranate) (Natural Medicines).
  • On file: Generalized anxiety disorder (GAD) — rated "Possibly Effective" (Ashwagandha) (Natural Medicines).
  • On file: Insomnia — rated "Possibly Effective" (Ashwagandha) (Natural Medicines).
  • On file: Stress — rated "Possibly Effective" (Ashwagandha) (Natural Medicines).
  • On file: Age-related cognitive decline — rated "Possibly Effective" (Phosphatidylserine) (Natural Medicines).

Ashwagandha and pomegranate have the strongest evidence in this formula. Ashwagandha is possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder.

Pomegranate is possibly effective for high blood pressure but research suggests it may not help high cholesterol or diabetes. Phosphatidylserine is possibly effective for age-related cognitive decline and Alzheimer disease.

Astaxanthin lacks sufficient evidence to rate its effectiveness for age-related cognitive decline, macular degeneration, aging skin, Alzheimer disease, athletic performance, or carpal tunnel syndrome.

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 4 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.

Ashwagandha is the ingredient with the most serious safety concerns. The safety data advises against its use during pregnancy due to traditional concerns about miscarriage risk, and there isn't enough information to use it while breastfeeding.

Rare cases of liver problems, including hepatitis and liver failure, have been reported. Astaxanthin and phosphatidylserine lack sufficient safety data during pregnancy and breastfeeding—talk with your doctor or pharmacist for personalized advice.

Pomegranate fruit and juice are generally safe as food, but concentrated extracts in supplements warrant caution, especially during pregnancy and breastfeeding, as safety data for supplements are limited. Common side effects across the ingredients include gastrointestinal upset (nausea, diarrhea, flatulence), headache, and insomnia at higher doses.

Ashwagandha may cause drowsiness.

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 — Pomegranate, Ashwagandha, Phosphatidylserine, Astaxanthin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,503 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 start, double-check with your doctor or pharmacist if you take any hepatotoxic drugs (medications that can harm the liver), blood pressure medications (antihypertensives), benzodiazepines or other sedatives, diabetes medications, blood thinners like warfarin, thyroid hormones, cholesterol drugs like rosuvastatin, anticholinergic or cholinergic drugs, or any medications metabolized by liver enzymes CYP3A4, CYP2B6, CYP2D6, CYP2C9, or CYP1A2. The ashwagandha and pomegranate in this product affect all of these categories.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product may appeal to you if you're interested in stress, anxiety, sleep support, or cognitive function—and if you have no relevant medication interactions. Because ashwagandha and pomegranate interact with a large number of drugs (especially blood pressure, blood thinner, diabetes, and thyroid medications), and because ashwagandha poses liver-safety risks, it's important to run your exact medications through the checker on this page before starting.

Talk with your doctor or pharmacist about whether TestosterZone is right for your situation and any medications you take.

KSM-66 Ashwagandha extract10 drug types · 1,373 drugs

Antidiabetes Drugs

Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
There is preliminary clinical evidence suggesting that ashwagandha might lower blood glucose levels. Theoretically, ashwagandha might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure. Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.

Likelihood Possible Evidence D
Benzodiazepines

Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin). This may also occur with other benzodiazepines.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking ashwagandha with hepatotoxic drugs might increase the risk of liver damage.
Ashwagandha has been linked to cases of acute hepatitis, liver failure, hepatic encephalopathy, autoimmune hepatitis, the need for liver transplantation, and death due to liver failure.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Ashwagandha has demonstrated immunostimulant effects in humans. Animal research has shown that ashwagandha can attenuate the immunosuppression caused by cyclophosphamide.

Likelihood Possible Evidence D
Thyroid Hormone

Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion. In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that ashwagandha extract induces CYP1A2 enzymes.

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

Theoretically, ashwagandha might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that ashwagandha extract induces CYP3A4 enzymes.

Likelihood Possible Evidence D
Serotonergic Drugs

Some animal studies have reported that ashwagandha can enhance serotonergic transmission by altering certain serotonin (5-HT) receptors. However, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects, and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs. Nevertheless, due to the lack of extensive studies on the matter and the fact that ashwagandha appears to affect serotonergic pathways, it would be prudent to exercise caution when combining it with drugs that affect serotonin.

Pomella9 drug types · 924 drugs

Ace Inhibitors (Aceis)

Theoretically, taking pomegranate with ACEIs might increase the risk of adverse effects.
Pomegranate juice is thought to have ACE inhibitor-like effects.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking pomegranate with antihypertensive drugs might increase the risk of hypotension.
Consuming pomegranate juice can modestly lower blood pressure.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP2D6.
In vitro, pomegranate juice inhibits CYP2D6. However, the clinical significance of this potential interaction in humans is not known.

Likelihood Possible Evidence D
Rosuvastatin (Crestor)

Theoretically, taking pomegranate with rosuvastatin might increase the risk of adverse effects.
In one case, a patient taking rosuvastatin 5 mg every other day in combination with ezetimibe 10 mg daily developed rhabdomyolysis after drinking pomegranate juice 200 mL twice weekly for 3 weeks. This patient had a history of elevated creatine kinase levels while not receiving any statin treatment. This suggests a possible underlying myopathy and predisposition to rhabdomyolysis.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, pomegranate might increase warfarin levels and increase the risk of bleeding. Also, discontinuing regular consumption of pomegranate juice might decrease warfarin levels.
In one case report, a patient had a stable, therapeutic bleeding time, as measured by international normalized ratio (INR), while taking warfarin in combination with pomegranate juice 2-3 times per week. The patient became subtherapeutic within about 10 days after discontinuing pomegranate juice, which required a warfarin dose increase. In another case report, a patient with a stable INR for over one year presented with an INR of 14. The patient noted no changes to medications or diet but did report consuming around 3 liters of pomegranate juice over the previous week. The patient's INR stabilized upon moderation of pomegranate juice consumption. The mechanism of this potential interaction is unclear.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, taking pomegranate with carbamazepine might increase the risk of adverse effects, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice may inhibit cytochrome P450 3A4 (CYP3A4) metabolism of carbamazepine and increase levels of carbamazepine by 1.5 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP3A4, but might not inhibit hepatic CYP3A4. However, some human research suggests that pomegranate does not significantly inhibit CYP3A4 drug metabolism in humans.

Likelihood Unlikely Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP2C9.
Some animal and in vitro research shows that pomegranate juice inhibits intestinal, but not hepatic, CYP2C9 isoenzyme activity. However, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans.

Likelihood Unlikely Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP3A4, but most research suggests this interaction is unlikely to be clinically significant.
Pomegranate contains several polyphenols that have individually been shown to inhibit CYP3A4. However, there is contradictory evidence about the effect of whole pomegranate juice on CYP3A4 activity. In vitro, pomegranate juice significantly inhibits the CYP3A4 enzyme, with comparable inhibition to grapefruit juice. In an animal model, pomegranate juice inhibits CYP3A4 metabolism of carbamazepine and increases levels of carbamazepine by 1.5 times; however, in human volunteers, drinking a single glass of pomegranate juice 240 mL or taking 200 mL daily for 2 weeks does not significantly affect levels of the CYP3A4 substrate midazolam after oral or intravenous administration. Another study in healthy volunteers shows that consuming pomegranate juice 300 mL three times daily for three days also does not significantly affect levels of simvastatin, a CYP3A4 substrate This suggests that pomegranate is unlikely to significantly affect levels of CYP3A4 substrates in humans.

Likelihood Unlikely Evidence B
Tolbutamide (Orinase)

Theoretically, pomegranate might increase levels of tolbutamide, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice inhibits the cytochrome P450 2C9 (CYP2C9) metabolism of tolbutamide. Pomegranate juice increased tolbutamide levels by 1.2 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP2C9, but might not inhibit hepatic CYP2C9. Despite this evidence, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans. This interaction does not appear to be clinically significant in humans.

TestosterZone by Progressive Professional from Progressive Laboratories: Common Questions

Does TestosterZone by Progressive Professional from Progressive Laboratories interact with any medications?
Yes. Based on its ingredients, TestosterZone has a known interaction with 1,502 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
TestosterZone 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 TestosterZone if I'm pregnant or breastfeeding?
Ashwagandha is likely unsafe in pregnancy due to miscarriage risk and isn't recommended while breastfeeding. Astaxanthin and phosphatidylserine lack enough safety data in pregnancy and lactation—don't guess. Pomegranate as food is likely fine, but the extract in supplements hasn't been well studied. Talk with your doctor or pharmacist before taking this product.
Does ashwagandha in this product cause drowsiness?
Yes, ashwagandha has been reported to cause drowsiness. If you're sensitive to sedation or drive frequently, this is worth discussing with your doctor or pharmacist, especially if you also take other sedating medications.
What does ashwagandha do?
Ashwagandha is possibly effective for insomnia, anxiety, stress, and generalized anxiety disorder. It's an adaptogenic herb traditionally used to help the body manage stress, though the strength of evidence varies by condition.
Will pomegranate in this product help my cholesterol?
No—research shows pomegranate is possibly ineffective for high cholesterol. It is possibly effective for high blood pressure, but only if you don't already take blood pressure medications, which could interact.
What are the most common side effects?
Gastrointestinal upset (nausea, diarrhea, flatulence), headache, and insomnia are the most commonly reported. These tend not to occur at typical doses, but higher amounts increase the risk, especially for insomnia and stomach pain.
Is there a link between ashwagandha and liver problems?
Yes—ashwagandha has been linked to rare but serious cases of acute hepatitis, liver failure, and other liver damage. This is why it's especially important to avoid combining it with other drugs known to harm the liver, and to stop and contact your doctor if you develop yellowing skin or eyes, dark urine, or severe abdominal pain.
