HelloPharmacist Scorecard of Co-Q Carnitine Complex by Maxi Health
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
Co-Q Carnitine Complex contains 2 active ingredients: Kaneka Q10 (coenzyme Q10) and L-carnitine. Coenzyme Q10 is a compound your cells use to generate energy and protect themselves from oxidative damage.
L-carnitine is an amino acid derivative that helps transport fatty acids into cells so they can be burned for energy. The capsule also contains inactive ingredients—cellulose, magnesium stearate, silicon dioxide, calcium carbonate, and silica for structure—plus a blend of digestive enzymes (bromelain, papain, lipase, amylase, and protease).
Does it work?
Moderate evidence
Coenzyme Q10 is rated likely effective for coenzyme Q10 deficiency and possibly effective for fibromyalgia, migraine headache, congestive heart failure, and diabetic neuropathy. L-carnitine is rated effective for L-carnitine deficiency and possibly effective for high cholesterol, congestive heart failure, and angina.
The evidence supporting this combination for any single condition isn't specified in our data; talk with your pharmacist about whether it's suited to your particular health goal.
How safe is it?
Well-documented data
Coenzyme Q10 is generally well tolerated when used as directed, though gastrointestinal side effects—appetite suppression, diarrhea, epigastric discomfort, heartburn, nausea, and vomiting—have been reported in less than 1% of people. Rarely, headache, dizziness, insomnia, skin itching, and allergic rash have been reported.
L-carnitine is also generally well tolerated at typical doses but can cause abdominal cramps, pain, diarrhea, gastritis, heartburn, nausea, and a fish-like body odor; high doses are more likely to trigger stomach upset. Seizures have been reported rarely.
Pregnancy safety has not been well studied for either ingredient, so avoid unless your doctor advises otherwise. Breastfeeding safety is also not well studied for either one; check with your doctor before use.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your pharmacist if you're on a blood thinner like warfarin or acenocoumarol (Moderate severity—it may decrease or increase the drug's effectiveness). Also flag thyroid hormone replacement (Moderate—L-carnitine may reduce its effectiveness) and any chemotherapy drugs that work through free radical damage, such as alkylating agents (Moderate—coenzyme Q10 may interfere with their activity).
If you're on blood pressure medication, let your pharmacist know, as minor additive effects are possible.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product may help if you have a documented coenzyme Q10 or L-carnitine deficiency, or if your doctor recommends it for heart health or migraine. If you take a blood thinner, thyroid medication, or chemotherapy, you need to check with your pharmacist first—the interactions are real and could change how your drugs work.
Pregnant or breastfeeding—talk to your doctor before starting.

Co-Q Carnitine Complex by Maxi Health Drug Interactions
HelloPharmacist Interaction Report
Co-Q Carnitine Complex by Maxi Health contains two active ingredients that both interact with blood thinners and have additional documented interactions with other medication types.
The most serious concern is with warfarin (Coumadin) and acenocoumarol (Sintrom), both blood thinners. Coenzyme Q10 may reduce warfarin's effectiveness—case reports document decreased blood thinner activity when the two were used together.
L-carnitine, the other active ingredient, may actually increase the anticoagulant effects of these same blood thinners, creating opposing risks depending on which ingredient dominates.
Read the full breakdown — every affected drug type, severity by severity
Coenzyme Q10 may also interact with chemotherapy drugs that rely on free radicals to work (alkylating agents like cyclophosphamide) by reducing their activity. Theoretically, its antioxidant properties could protect cancer cells from treatment.
L-carnitine can interfere with thyroid hormone replacement by blocking the hormone's entry into cells and reducing its effectiveness. Coenzyme Q10 may cause additive blood pressure–lowering effects if you're already on antihypertensive medications.
Altogether, these interactions span 213 individual medications. Before starting this product, use the medication checker on this page to verify your exact prescriptions—especially if you take a blood thinner, chemotherapy drug, or thyroid replacement.

For each ingredient in Co-Q Carnitine Complex 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.
Kaneka 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.
Carnitine
Acenocoumarol (Sintrom)
Theoretically, L-carnitine might increase the anticoagulant effects of acenocoumarol.
L-carnitine might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant similar to warfarin, but shorter-acting. There are at least two case reports of INR elevation with concomitant use. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product.
Thyroid Hormone
Theoretically, L-carnitine might decrease the effectiveness of thyroid hormone replacement.
L-carnitine appears to act as a peripheral thyroid hormone antagonist by inhibiting entry of thyroid hormone into the nucleus of cells. Taking L-carnitine also seems to diminish some of the symptoms of hyperthyroidism.
Warfarin (Coumadin)
Theoretically, L-carnitine might increase the anticoagulant effects of warfarin.
L-carnitine might increase the anticoagulant effects of acenocoumarol, a shorter-acting oral anticoagulant similar to warfarin. There is not enough information to know whether this interaction occurs with L-carnitine and warfarin.
