What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This softgel contains 2 active ingredients. Ubiquinone, a form of coenzyme Q10, is a compound your body makes naturally and uses in energy production and as an antioxidant.

D-limonene is a natural compound found in citrus peel. The remaining ingredients—ethyl oleate, gelatin, polysorbate 80, glycerin, purified water, carob color, D-alpha-tocopherol, and rosemary extract—are inactive components that help deliver and preserve the product.

Does it work?

Strong 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.

Strong

Strong 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: Coenzyme Q10 deficiency — rated "Likely Effective" (Coenzyme Q10) (Natural Medicines).
  • On file: Migraine headache — rated "Possibly Effective" (Coenzyme Q10) (Natural Medicines).
  • On file: Congestive heart failure (CHF) — rated "Possibly Effective" (Coenzyme Q10) (Natural Medicines).
  • On file: Diabetic neuropathy — rated "Possibly Effective" (Coenzyme Q10) (Natural Medicines).
  • On file: Fibromyalgia — rated "Possibly Effective" (Coenzyme Q10) (Natural Medicines).

Ubiquinone has the strongest evidence for treating coenzyme Q10 deficiency, where it's likely effective. For fibromyalgia, migraine headache, congestive heart failure, and diabetic neuropathy, the evidence suggests it's possibly effective, though the research isn't conclusive.

D-limonene's effectiveness for cancer and irritable bowel syndrome has not been established in the data we hold—there isn't enough reliable evidence to rate it either way for those uses.

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Ubiquinone is generally well tolerated by most adults when used as directed. The most common side effects are gastrointestinal—appetite suppression, diarrhea, epigastric discomfort, heartburn, nausea, and vomiting—occurring in less than 1% of people.

Headache, dizziness, and insomnia have been reported rarely; dividing daily doses above 100 mg may help minimize GI effects. Skin itching and allergic rash have also been reported in small numbers of users.

Pregnancy safety data for ubiquinone is not on file; there isn't enough reliable safety information to know either way, so talk with your doctor or pharmacist for personalized advice. Breastfeeding safety has not been well studied; use caution and check with your doctor.

D-limonene is generally well tolerated in food amounts, but high-dose supplement safety data in humans is limited. It may cause nausea, vomiting, and diarrhea orally, and contact dermatitis topically.

When inhaled (as from household cleaning products), increased exposure to ambient limonene has been linked to wheezing and asthma, particularly in children. There is not enough safety data for supplement doses during pregnancy or breastfeeding to recommend it; talk with your doctor or pharmacist.

Meds to double-check

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?
  • 2 of the 2 matched ingredients can interact with medications — Coenzyme Q10, Limonene.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 406 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 taking this product, check with your doctor or pharmacist if you take warfarin or any blood-thinning medication, as ubiquinone may reduce its effectiveness. Also double-check if you're on chemotherapy drugs, particularly alkylating agents, since ubiquinone's antioxidant effects might interfere with their action.

Blood pressure medications warrant review too, as ubiquinone may add to their effect. Finally, if you take medications processed by your liver's CYP2C19 or CYP2C9 enzymes—including certain antiarrhythmics, antifungals, anticonvulsants, or nonsteroidal anti-inflammatory drugs—the limonene in this product may theoretically affect their levels, so confirm with your pharmacist.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you have a coenzyme Q10 deficiency or are exploring options for heart health, migraines, or nerve-related pain—though the evidence is stronger for deficiency than for the others. If you take warfarin or any chemotherapy drug, or if you're on blood pressure medication, check your exact drug names with your doctor or pharmacist before starting, because the interactions documented here could affect how those medications work.

Pregnancy and breastfeeding are times to talk it over with your healthcare provider first.

D-Limonene5 drug types · 229 drugs

Cytochrome P450 2C19 (Cyp2C19) Inducers

There's preliminary evidence that limonene might be a substrate for cytochrome P450 2C19 (CYP2C19). CYP2C19 inducers might decrease the effects of limonene. So far, this interaction has not been reported in humans. Inducers of CYP2C19 include carbamazepine (Tegretol), prednisone (Deltasone), and rifampin (Rifadin, Rimactane).

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Inhibitors

There's preliminary evidence that limonene might be a substrate for cytochrome P450 2C19 (CYP2C19). So far, this interaction has not been reported in humans. However, watch for an increase in the limonene levels when it is taken with drugs that inhibit CYP2C19. Some drugs that inhibit CYP2C19 include cimetidine (Tagamet), fluvoxamine (Luvox), omeprazole (Prilosec); ticlopidine (Ticlid), topiramate (Topamax), and others.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Inducers

There's preliminary evidence that limonene might be a substrate for cytochrome P450 2C9 (CYP2C9). Inducers of CYP2C9 might decrease limonene levels. Inducers of CYP2C9 include rifampin (Rifadin, Rimactane) and secobarbital (Seconal).

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Inhibitors

There's preliminary evidence that limonene might be a substrate for cytochrome P450 2C9 (CYP2C9). So far, this interaction has not been reported in humans. However, watch for side effects in patients taking limonene and CYP2C9 inhibitors. Some CYP2C9 inhibitors include amiodarone (Cordarone), fluconazole (Diflucan), lovastatin (Mevacor), paroxetine (Paxil), zafirlukast (Accolate), and many others.

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

There's preliminary evidence that limonene might be a substrate for cytochrome P450 2C9 (CYP2C9), as well causing its induction. So far, this interaction has not been reported in humans. However, watch for a decrease in the levels of drugs metabolized by CYP2C9 in patients taking limonene. Some drugs metabolized by CYP2C9 include nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac (Cataflam, Voltaren), ibuprofen (Motrin), meloxicam (Mobic), and piroxicam (Feldene); celecoxib (Celebrex); amitriptyline (Elavil); warfarin (Coumadin); glipizide (Glucotrol); losartan (Cozaar); and others.

Likelihood Possible Evidence D

Ubiquinone3 drug types · 198 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Super-Absorbable CoQ10 100 mg by Life Extension: Common Questions

Does Super-Absorbable CoQ10 100 mg by Life Extension interact with any medications?
Yes. Based on its ingredients, Super-Absorbable CoQ10 100 mg has a known interaction with 406 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Super-Absorbable CoQ10 100 mg contains 2 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.
Is this product safe during breastfeeding?
Breastfeeding safety for ubiquinone has not been well studied; there isn't enough data to know either way. D-limonene is rated likely safe during breastfeeding based on the available information, but the data on supplement doses is limited. Talk with your doctor or pharmacist about your specific situation before taking it.
What are the most common side effects?
Gastrointestinal effects are the most common—appetite suppression, diarrhea, epigastric discomfort, heartburn, nausea, and vomiting—occurring in less than 1% of people. Headache, dizziness, and insomnia have been reported rarely. If you're taking more than 100 mg daily, dividing the dose may help reduce GI effects.
Does this product actually work?
Ubiquinone is likely effective for treating coenzyme Q10 deficiency and possibly effective for fibromyalgia, migraine, heart failure, and diabetic neuropathy—though the evidence for those conditions isn't as strong. D-limonene's usefulness for cancer or irritable bowel syndrome isn't established in the data we hold.
What is ubiquinone, and why is it in this product?
Ubiquinone is coenzyme Q10, a compound your body naturally makes and uses in energy production and as an antioxidant. Supplementing it may help if your body's levels are low or if you're exploring support for heart health or certain types of pain.
Can I take this with my blood pressure medication?
Ubiquinone may have an additive effect with blood pressure medications and theoretically lower blood pressure further. Check with your doctor or pharmacist before taking this product alongside any blood pressure medication to make sure it's safe for you.
Is there any risk if I take warfarin?
Yes. Ubiquinone may reduce warfarin's blood-thinning effects—four cases of decreased warfarin efficacy linked to coenzyme Q10 have been reported. Do not take this product if you're on warfarin without checking with your doctor or pharmacist first.
