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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

CoQWell contains 3 active ingredients. Vitamin E supports antioxidant health and is effective for vitamin E deficiency and a genetic condition called AVED (ataxia with vitamin E deficiency); it's possibly effective for Alzheimer disease, beta-thalassemia, and G6PD deficiency.

CoQsol Coenzyme Q10 is a naturally occurring compound your cells need for energy; it's likely effective for CoQ10 deficiency and possibly effective for fibromyalgia, migraine, heart failure, and diabetic nerve pain. Betatene is a plant-derived source of vitamin A, effective for vitamin A deficiency and possibly effective for skin aging, measles, and ulcerative colitis.

The remaining ingredients are inactive fillers and softgel capsule materials.

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: Vitamin A deficiency — rated "Effective" (Vitamin A) (Natural Medicines).
  • On file: Vitamin E deficiency — rated "Effective" (Vitamin E) (Natural Medicines).
  • On file: Ataxia with vitamin E deficiency (AVED) — rated "Effective" (Vitamin E) (Natural Medicines).
  • On file: Coenzyme Q10 deficiency — rated "Likely Effective" (Coenzyme Q10) (Natural Medicines).
  • On file: Aging skin — rated "Possibly Effective" (Vitamin A) (Natural Medicines).

The three active ingredients have varying evidence levels. Vitamin E is established (Effective) only for vitamin E deficiency and AVED; for Alzheimer disease, beta-thalassemia, and G6PD deficiency, the evidence is Possibly Effective.

CoQsol Coenzyme Q10 is Likely Effective for CoQ10 deficiency itself and Possibly Effective for fibromyalgia, migraine, heart failure, and diabetic neuropathy. Betatene (vitamin A) is Effective for vitamin A deficiency and Possibly Effective for oral leukoplakia, aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia.

The evidence supporting each ingredient's use depends on which condition you're targeting.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

At normal dietary amounts, all three ingredients are generally well tolerated. However, high-dose long-term supplements — especially vitamin E — may raise bleeding risk, and vitamin A builds up in your body and can become toxic at high doses.

Vitamin E at doses above 400 IU daily with blood thinners or above 1,000 IU daily alone has caused hemorrhagic stroke (bleeding in the brain) in some studies; serious adverse effects are rare but include bleeding and cardiovascular complications. CoQsol is well tolerated in most people; gastrointestinal side effects like nausea, diarrhea, and heartburn occur in less than 1% of users.

For pregnancy, the facts do not provide safety data for vitamin E or CoQsol, so talk with your doctor before taking them during pregnancy or while breastfeeding. Vitamin A in high doses — especially as retinol — can cause birth defects and should be avoided during pregnancy; normal dietary and recommended amounts are appropriate.

The bottom line

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

CoQWell may help if you have a documented deficiency of vitamin E, CoQ10, or vitamin A, or if you're considering it for conditions like migraine or heart failure — but the evidence is strongest for deficiency itself. If you take blood thinners like warfarin, chemotherapy drugs, retinoid skin medications, or cyclosporine, check with your pharmacist first: the interactions here are real and dose matters.

Stick to the label dose, and talk to your pharmacist or doctor if you're pregnant, breastfeeding, or taking any prescription medications.

Vitamin E8 drug types · 764 drugs

Alkylating Agents

Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of alkylating agents.
There's concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin E have on chemotherapy. Advise patients to consult their oncologist before using vitamin E supplements, especially in high doses.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Concomitant use of vitamin E and anticoagulant or antiplatelet agents might increase the risk of bleeding.
Vitamin E seems to inhibit of platelet aggregation and antagonize the effects of vitamin K-dependent clotting factors. These effects appear to be dose-dependent, and are probably only likely to be clinically significant with doses of at least 800 units daily. Mixed tocopherols, such as those found in food, might have a greater antiplatelet effect than alpha-tocopherol. RRR alpha-tocopherol (natural vitamin E) 1000 IU daily antagonizes vitamin K-dependent clotting factors. Advise patients to avoid high doses of vitamin E, especially in people with low vitamin K intake or other risk factors for bleeding.

Likelihood Possible Evidence B
Antitumor Antibiotics

Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of antitumor antibiotics.
There's concern that antioxidants could reduce the activity of antitumor antibiotic drugs such as doxorubicin, which generate free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin E have on chemotherapy involving antitumor antibiotics. Advise patients to consult their oncologist before using vitamin E supplements, especially in high doses.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

A specific form of vitamin E might increase absorption and levels of cyclosporine.
There is some evidence that one specific formulation of vitamin E (D-alpha-tocopheryl-polyethylene glycol-1000 succinate, TPGS, tocophersolan, Liqui-E) might increase absorption of cyclosporine. This vitamin E formulation forms micelles which seems to increase absorption of cyclosporine by 40% to 72% in some patients. However, this interaction is unlikely to occur with the usual forms of vitamin E.

Likelihood Unlikely Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, vitamin E might induce metabolism of CYP3A4, possibly reducing the levels CYP3A4 substrates.
Vitamin E appears to bind with the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. Although the clinical significance of this is not known, use caution when considering concomitant use of vitamin E and other drugs affected by these enzymes.

Likelihood Possible Evidence D
Selumetinib (Koselugo)

Taking selumetinib with vitamin E can result in a total daily dose of vitamin E that exceeds safe limits and therefore might increase the risk of bleeding.
Selumetinib contains 48-54 IU vitamin E per capsule. The increased risk of bleeding with vitamin E appears to be dose-dependent. Be cautious when using selumetinib in combination with supplemental vitamin E, especially in patients at higher risk of bleed, such as those with chronic conditions and those taking antiplatelet drugs.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Using vitamin E with warfarin might increase the risk of bleeding.
Due to interference with production of vitamin K-dependent clotting factors, use of more than 400 IU of vitamin E daily with warfarin might increase prothrombin time (PT), INR, and the risk of bleeding,. At a dose of 1000 IU per day, vitamin E can antagonize vitamin K-dependent clotting factors even in people not taking warfarin. Limited clinical evidence suggests that doses up to 1200 IU daily may be used safely by patients taking warfarin, but this may not be applicable in all patient populations.

Likelihood Possible Evidence B
Niacin

Vitamin E might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises high-density lipoprotein (HDL) cholesterol levels in people with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50%. Vitamin E alone combined with a statin does not seem to decrease HDL levels. It is not known whether the adverse effect on HDL is due to one of the other antioxidants or to the combination. It also is not known whether it will occur in other patient populations.

Likelihood Possible Evidence A
Vitamin E full monograph & interactions

Betatene4 drug types · 387 drugs

Retinoids

Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements.

Likelihood Probable Evidence D
Hepatotoxic Drugs

Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.

Likelihood Possible Evidence C
Tetracycline Antibiotics

Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism. Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.

Likelihood Possible Evidence D
Betatene full monograph & interactions

CoQsol Coenzyme Q103 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.

CoQWell by Live Conscious: Common Questions

Does CoQWell by Live Conscious interact with any medications?
Yes. Based on its ingredients, CoQWell has a known interaction with 1,113 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CoQWell contains 3 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.
What is Betatene and why is it in this product?
Betatene is a plant-derived form of vitamin A. It's included because vitamin A supports vision, immune function, and skin health. The product's facts show it's effective for vitamin A deficiency and possibly effective for aging skin and oral leukoplakia, among other uses.
Can I take this if I'm pregnant or nursing?
For vitamin E and CoQsol Coenzyme Q10, there isn't enough safety data, so talk with your doctor before taking them during pregnancy or breastfeeding. High-dose vitamin A should be avoided during pregnancy because it can cause birth defects, but normal dietary and recommended amounts are appropriate.
What are the most common side effects?
Vitamin E and vitamin A are generally well tolerated at normal doses. CoQsol is also well tolerated; the most common side effects are mild gastrointestinal issues like nausea, diarrhea, or heartburn, occurring in less than 1% of users — these often improve if you divide the dose or take it with food.
Is this safe to take long-term?
At recommended doses, yes — vitamin A, E, and CoQ10 are generally well tolerated. However, the facts caution that high-dose long-term vitamin E supplements may raise bleeding risk. Stick to the label dose and check with your pharmacist if you're taking it for more than a few months or if you notice unusual bruising or bleeding.
Does this product contain any fillers or artificial ingredients?
The inactive ingredients are rice bran oil, gelatin, glycerin, water, beeswax, and annatto fruit extract — these are the softgel capsule materials and carriers, not fillers in the sense of inert binders.
Can I take this with my blood pressure medication?
CoQsol Coenzyme Q10 may theoretically add to the blood-pressure-lowering effect of your medication (Minor interaction). Check with your pharmacist — you may need your blood pressure monitored more closely or your medication adjusted.
