HelloPharmacist Scorecard of CoQ10 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
Wonder Laboratories CoQ10 has 2 active ingredients. Coenzyme Q10 is a compound your body makes naturally and uses for energy production in your cells.
BioPerine is a concentrated form of piperine, the active compound in black pepper, often added to supplements to help your body absorb other ingredients better. The product also contains inactive ingredients (vegetable cellulose, gelatin, and vegetable magnesium stearate) that serve as the capsule material and binding agents.
Does it work?
Strong evidence
Coenzyme Q10 is likely effective for CoQ10 deficiency itself. There's also possibly good evidence it may help with fibromyalgia, migraine headaches, congestive heart failure, and diabetic neuropathy—though the research isn't conclusive.
For BioPerine (black pepper), the data we hold shows insufficient evidence to rate it for allergic rhinitis, asthma, athletic performance, headache, depression, or diarrhea. That means we don't have strong enough research to say whether it works for these uses.
How safe is it?
Well-documented data
Coenzyme Q10 is generally well tolerated. Gastrointestinal side effects like nausea, diarrhea, heartburn, and appetite suppression occur in less than 1% of people, and dividing doses above 100 mg daily can minimize them.
Headache, dizziness, insomnia, and skin itching have been reported rarely. Black pepper used in food amounts is generally safe, but concentrated piperine supplements should be used cautiously.
The most common side effects are a burning aftertaste, indigestion, and reduced taste perception. Allergic reactions are rare but possible in sensitive people.
For pregnancy, BioPerine is rated likely safe, though one rating flags it as likely unsafe—talk with your doctor about your individual situation. CoQ10 data doesn't cover pregnancy safety, so there isn't enough information to know either way; discuss this with your pharmacist or doctor.
Neither ingredient has adequate safety data for breastfeeding, so check with your doctor before using if you're nursing.
Meds to double-check
Moderate interaction found
Check with your pharmacist before using if you take warfarin (a blood thinner)—CoQ10 may make it less effective. Also double-check if you use propranolol, seizure medications like phenytoin, HIV drugs like nevirapine, tuberculosis antibiotics like rifampin, or theophylline for asthma; black pepper in this product may raise their blood levels.
Blood-pressure medications and certain chemotherapy drugs warrant a quick conversation too.
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.
This product could be worth considering if you have a CoQ10 deficiency or want to explore it for migraine or heart-related concerns, but the BioPerine component means you need to check your medications first—especially blood thinners, seizure drugs, heart medications, and antiretrovirals. If you're pregnant, nursing, or taking any prescription drugs, talk to your pharmacist before starting.

Formula
High Aborption CoQ10 contains pure coenzyme Q10 plus Bioperine. CoQ10 is a nutrient that supports heart function and promotes energy production in cells. Bioperine, a standardized herbal extract derived from black pepper fruit, promotes absorption of nutrients in the GI tract. Preliminary studies have demonstrated that Bioperine increases CoQ10 absorption.

CoQ10 by Wonder Laboratories Drug Interactions
HelloPharmacist Interaction Report
Wonder Laboratories CoQ10 contains two active ingredients, and one of them—BioPerine (black pepper)—does interact with medications.
BioPerine may increase blood levels of propranolol (a heart and blood-pressure medication), potentially making it stronger than intended. The same goes for nevirapine (an HIV drug), rifampin (a tuberculosis antibiotic), phenytoin (a seizure medication), and theophylline (an asthma drug)—all moderate-severity concerns.
Black pepper may also theoretically raise levels of cyclosporine (an immunosuppressant), atorvastatin (a cholesterol drug), and pentobarbital (a sedative), though human evidence is limited.
Read the full breakdown — every affected drug type, severity by severity
Coenzyme Q10, the other active ingredient, has its own documented interactions. It may reduce how well warfarin (a blood thinner) works—there are a few case reports of this happening.
Additionally, CoQ10 could theoretically add to the blood-pressure-lowering effects of antihypertensive medications, which is a minor concern. There's also a theoretical risk that CoQ10's antioxidant effects might interfere with certain chemotherapy drugs that rely on generating free radicals to work.
Altogether, these interactions span 1,159 individual medications. If you take any of the drug types mentioned above—or any prescription medication at all—use the checker below to see if this product is right for you before you start.

For each ingredient in CoQ10 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.
BioPerine
Anticoagulant/Antiplatelet Drugs
Theoretically, black pepper might increase the risk of bleeding when taken with antiplatelet or anticoagulant drugs.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit platelet aggregation. This has not been reported in humans.
Antidiabetes Drugs
Theoretically, black pepper might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that piperine, a constituent of black pepper, can reduce blood glucose levels. Monitor blood glucose levels closely. Dose adjustments might be necessary.
Atorvastatin (Lipitor)
Theoretically, black pepper might increase blood levels of atorvastatin.
Animal research shows that taking piperine, a constituent of black pepper, 35 mg/kg can increase the maximum serum concentration of atorvastatin three-fold. This has not been reported in humans.
Cyclosporine (Neoral, Sandimmune)
Theoretically, black pepper might increase the effects and side effects of cyclosporine.
In vitro research shows that piperine, a constituent of black pepper, increases the bioavailability of cyclosporine. This has not been reported in humans.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, black pepper might increase levels of drugs metabolized by CYP2D6.
In vitro research suggests that some constituents of black pepper inhibit CYP2D6. This has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.
Lithium
Theoretically, black pepper might increase blood levels of lithium due to its diuretic effects. The dose of lithium might need to be reduced.
Black pepper is thought to have diuretic properties.
Nevirapine (Viramune)
Black pepper might increase blood levels of nevirapine.
Clinical research shows that piperine, a constituent of black pepper, increases the plasma concentration of nevirapine. However, no adverse effects were observed in this study.
P-Glycoprotein Substrates
Theoretically, black pepper might increase levels of P-glycoprotein substrates.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit P-glycoprotein.
Pentobarbital (Nembutal)
Theoretically, black pepper might increase the sedative effects of pentobarbital.
Animal research shows that piperine, a constituent of black pepper, increases pentobarbital-induced sleeping time.
Phenytoin (Dilantin)
Black pepper might increase blood levels of phenytoin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin. Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin. Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper.
Propranolol (Inderal)
Black pepper might increase blood levels of propranolol.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol.
Rifampin (Rifadin)
Black pepper might increase blood levels of rifampin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and serum levels of rifampin.
Theophylline
Black pepper might increase blood levels of theophylline.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of theophylline.
Amoxicillin (Amoxil, Trimox)
Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin. This has not been reported in humans.
Carbamazepine (Tegretol)
Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects. In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, black pepper might decrease levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that black pepper induces CYP1A2. This has not been reported in humans.
Coenzyme Q10
Alkylating Agents
Coenzyme Q10 has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals.
Theoretically, antioxidants such as coenzyme Q10 might protect tumor cells from chemotherapeutic agents that work by inducing oxidative stress, such as alkylating agents (e.g., cyclophosphamide) and radiation therapy. The clinical importance of this interaction is unknown.
Warfarin (Coumadin)
Coenzyme Q10 is chemically similar to menaquinone and might have vitamin K-like procoagulant effects, which could decrease the effects of warfarin.
Concomitant use of coenzyme Q10 and warfarin might reduce the anticoagulant effects of warfarin. Four cases of decreased warfarin efficacy thought to be due to coenzyme Q10 have been reported. However, there is some preliminary clinical research that suggests coenzyme Q10 might not significantly decrease the effects of warfarin in patients who have a stable INR.
Antihypertensive Drugs
Theoretically, coenzyme Q10 might have additive effects with antihypertensive drugs.
Some clinical research shows that coenzyme Q10 can significantly lower blood pressure, although other studies have shown conflicting results.
