HelloPharmacist Scorecard of Co Q-10 100 mg plus L-Carnitine by Nature's Bounty
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
This softgel contains two active ingredients: L-carnitine and Q-Sorb Coenzyme Q10 (coQ10). L-carnitine is an amino acid your body uses for energy metabolism, particularly in heart and muscle cells.
Coenzyme Q10 is a naturally occurring compound that supports cellular energy production and acts as an antioxidant. The product also includes inactive ingredients — rice bran oil, gelatin, vegetable glycerin, soy lecithin, and natural caramel color — which serve as the capsule and carrier.
Does it work?
Strong evidence
L-carnitine is effective for treating L-carnitine deficiency and possibly effective for high cholesterol and congestive heart failure. It's also possibly effective for angina (chest pain).
Coenzyme Q10 is likely effective for coQ10 deficiency and possibly effective for fibromyalgia, migraine headaches, heart failure, and diabetic nerve pain. The evidence we hold doesn't establish effectiveness for other uses.
How safe is it?
Well-documented data
Both ingredients are generally well tolerated at typical doses. L-carnitine's most common side effects are stomach upset — including nausea, diarrhea, heartburn, and abdominal cramping — and a fishy body odor; seizures are rare.
Coenzyme Q10 causes gastrointestinal side effects in less than 1% of users, and headache or dizziness occasionally. L-carnitine safety during pregnancy isn't well established and requires medical supervision; it's possibly safe during breastfeeding, though data is limited.
Coenzyme Q10 safety during pregnancy isn't on file; during breastfeeding, safety hasn't been well studied, so check with your doctor.
Meds to double-check
Moderate interaction found
Double-check this product if you take blood thinners (warfarin or acenocoumarol) — L-carnitine may boost their effect while coQ10 may reduce it, requiring dose adjustments. Also run through the checker if you're on thyroid hormone replacement, blood pressure medication, or chemotherapy drugs like cyclophosphamide, which this product may interfere with.
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 combination may help with heart health, energy, or migraine prevention if you have a coQ10 deficiency or certain heart conditions — talk to your pharmacist about whether it fits your situation. Anyone taking blood thinners, thyroid medication, blood pressure drugs, or chemotherapy needs to check their specific medications before starting.
If you have stomach sensitivity or are pregnant or breastfeeding, discuss this product with your doctor first.

Co Q-10 100 mg plus L-Carnitine by Nature's Bounty Drug Interactions
HelloPharmacist Interaction Report
Co Q-10 100 mg plus L-Carnitine by Nature's Bounty contains two active ingredients, each with documented interactions.
The most serious concern is L-carnitine with blood thinners (anticoagulants): it may increase the effects of warfarin and acenocoumarol, raising your bleeding risk. Coenzyme Q10 works the opposite way — it may reduce warfarin's anticoagulant effect, potentially lowering your protection against clots.
Read the full breakdown — every affected drug type, severity by severity
L-carnitine also may decrease how well thyroid hormone replacement works by blocking its entry into cells. Coenzyme Q10 can theoretically reduce the effectiveness of certain chemotherapy drugs (alkylating agents) that rely on oxidative stress to kill cancer cells, and may cause an additive blood-pressure-lowering effect with antihypertensive medications.
Altogether, these interactions span 215 individual medications.
If you're on any of these drug types—blood thinners, thyroid hormones, cancer treatment, or blood pressure medication—check your exact medications with the search tool below before starting this product.

For each ingredient in Co Q-10 100 mg plus L-Carnitine 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.
Q-Sorb 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.
L-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.
