HelloPharmacist Scorecard of PQQ CoQ-10 by Solaray
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
Solaray's PQQ CoQ-10 has four active ingredients: N-acetyl cysteine, coenzyme Q-10, L-glutathione, and pyrroloquinoline quinone disodium salt. The product also contains cellulose and silica as inactive ingredients (binders and capsule material).
N-acetyl cysteine is an amino acid used to help clear thick mucus and protect against acetaminophen poisoning. Coenzyme Q-10 is a compound your cells make and use for energy production and antioxidant support.
The other two actives support cellular energy and antioxidant function, though we've no documented interactions data for them.
Does it work?
Moderate evidence
N-acetyl cysteine is effective for acetaminophen poisoning, certain airway conditions (atelectasis and tracheostomy care), and diagnostic bronchial studies; it's possibly effective for bronchitis. Coenzyme Q-10 is likely effective for CoQ-10 deficiency (a real nutrient gap in some people) and possibly effective for fibromyalgia, migraines, heart failure, and diabetic nerve pain (neuropathy).
We hold no effectiveness data for L-glutathione or pyrroloquinoline quinone disodium salt in our facts.
How safe is it?
Well-documented data
N-acetyl cysteine is generally well tolerated at typical doses, though doses over 9 grams in a single use or more than 30 grams daily can bring on problems. Common oral side effects include diarrhea, dry mouth, indigestion, heartburn, nausea, and vomiting.
Joint pain was reported in over 15% of patients in one trial. Pregnancy safety is rated possibly safe, but safety data during pregnancy hasn't been well studied — talk to your doctor.
Coenzyme Q-10 is generally well tolerated; no serious side effects have been reported in clinical studies. Mild gastrointestinal effects (loss of appetite, diarrhea, nausea, vomiting, heartburn) occur in less than 1% of people and often improve if daily doses above 100 mg are split.
Headache, dizziness, and insomnia have been reported rarely. There isn't enough safety data for pregnancy, so avoid use unless your doctor advises otherwise; breastfeeding safety also hasn't been well studied.
Meds to double-check
Major interaction found
Before you take this, check with your pharmacist if you're on nitroglycerin or any blood thinner (especially warfarin). Blood pressure medications, chemotherapy drugs, chloroquine, and activated charcoal are also worth double-checking against your exact list.
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.
If you take nitroglycerin, blood thinners like warfarin, blood pressure medications, or chemotherapy, you need to talk with your pharmacist or doctor before starting this product. Even if you're not on those specific drugs, run your medication list through the checker below — this product touches a lot of medications.
CoQ-10 and NAC can both help, but only when it's safe for your situation.

PQQ CoQ-10 by Solaray Drug Interactions
HelloPharmacist Interaction Report
Solaray's PQQ CoQ-10 contains two ingredients with documented interactions.
N-acetyl cysteine carries a Major interaction with nitroglycerin (the heart medication), which can cause dangerous drops in blood pressure and severe headaches — this is the most serious concern. It also has Moderate interactions with blood pressure medications (antihypertensives), blood thinners (anticoagulants and antiplatelet drugs), chloroquine (an antimalarial), and activated charcoal, each affecting how those drugs work or how well they're absorbed.
Read the full breakdown — every affected drug type, severity by severity
Coenzyme Q-10 has Moderate interactions with chemotherapy drugs called alkylating agents and with warfarin (a blood thinner), potentially reducing their effectiveness. It carries a Minor interaction with other blood pressure medications, which may add to their effect.
We could not check two ingredients — L-glutathione and pyrroloquinoline quinone disodium salt — because we hold no interaction data for them. Altogether, these interactions span 318 individual medications.

For each ingredient in PQQ CoQ-10 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.
N-Acetyl Cysteine
Nitroglycerin
N-acetyl cysteine can increase the risk for hypotension and headaches when taken with intravenous or transdermal nitroglycerin.
Clinical research shows that concomitant administration of N-acetyl cysteine and intravenous or transdermal nitroglycerin can cause severe hypotension and intolerable headaches. Furthermore, in vitro research suggests that N-acetyl cysteine increases the anticoagulant activity of nitroglycerin.
Activated Charcoal
N-acetyl cysteine might reduce the effects of activated charcoal, while activated charcoal might reduce the absorption of N-acetyl cysteine.
N-acetyl cysteine appears to reduce the capacity of activated charcoal to adsorb acetaminophen and salicylic acid. Conversely, although clinical research suggests that although activated charcoal can reduce the absorption of N-acetyl cysteine by up to 40%, it does not seem to reduce its clinical effects. Other clinical evidence suggests that activated charcoal does not affect the absorption of N-acetyl cysteine.
Anticoagulant/Antiplatelet Drugs
Theoretically, N-acetyl cysteine might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Clinical research suggests that intravenous N-acetyl cysteine decreases prothrombin time, prolongs coagulation time, decreases platelet aggregation, and increases blood loss in surgical patients. Furthermore, in vitro research suggests that N-acetyl cysteine increases the anticoagulant activity of nitroglycerin.
Antihypertensive Drugs
Theoretically, N-acetyl cysteine might increase the risk of hypotension when taken with antihypertensive drugs.
Animal research suggests that N-acetyl cysteine potentiates the hypotensive effects of the angiotensin-converting enzyme inhibitors (ACEIs) captopril and enalaprilat. Theoretically, combining N-acetyl cysteine with other antihypertensive drugs might increase the risk of hypotension.
Chloroquine (Aralen)
Theoretically, N-acetyl cysteine might interfere with the antimalarial effects of chloroquine.
Animal research suggests that N-acetyl cysteine might reduce the antimalarial effects of chloroquine by increasing cellular levels of glutathione.
Coenzyme Q-10
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.
