HelloPharmacist Scorecard of Quinogel 100 mg Double Strength by Swanson
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
Quinogel 100 mg Double Strength is a single-ingredient supplement containing coenzyme Q10 (CoQ10) in ubiquinol form — the form your body prefers to use. CoQ10 is a compound your cells make naturally and use to produce energy and protect themselves from damage.
The softgel capsule also contains inactive ingredients (medium-chain triglyceride, polysorbate 80, gelatin, glycerin, sorbitol, ascorbyl palmitate, purified water, and annatto suspension) that help deliver the active ingredient.
Does it work?
Strong evidence
CoQ10 is likely effective for CoQ10 deficiency itself. For other uses — fibromyalgia, migraine headache, congestive heart failure, and diabetic nerve damage — the evidence suggests it's possibly effective, meaning research shows promise but isn't yet definitive.
Talk with your doctor about whether CoQ10 makes sense for your specific situation.
How safe is it?
Well-documented data
CoQ10 is generally well tolerated by most adults at typical doses. In clinical studies, no serious side effects have been reported.
The most common mild effects — seen in less than 1% of users — are stomach-related: appetite loss, diarrhea, stomach discomfort, heartburn, nausea, or vomiting. These can often be reduced by splitting daily doses above 100 mg.
Headache, dizziness, and insomnia have been reported occasionally. Skin itching and rash are rare.
There isn't enough reliable safety data on CoQ10 in pregnancy, so it's best to avoid it unless your doctor advises otherwise. Safety during breastfeeding hasn't been well studied either, so talk with your doctor before using it.
Meds to double-check
Moderate interaction found
Before taking Quinogel 100 mg, check with your doctor or pharmacist if you take warfarin or other blood thinners — CoQ10 may reduce their effect and increase your clot risk. Also clear it if you're on chemotherapy drugs (especially alkylating agents like cyclophosphamide) or blood pressure medications, as CoQ10 could interfere with both.
No interactions are documented in our data for most other medication types.
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.
CoQ10 may help if you have a documented deficiency or want to explore it for heart health, migraines, or nerve pain — the evidence is promising but not ironclad. If you take warfarin, chemotherapy drugs, or blood pressure medications, you need to check with your doctor or pharmacist before starting; this product could interfere with how those work.
Pregnant or breastfeeding? Talk it over with your healthcare provider first.

Quinogel 100 mg Double Strength by Swanson Drug Interactions
HelloPharmacist Interaction Report
Quinogel 100 mg Double Strength from Swanson contains coenzyme Q10 (CoQ10), which interacts with three major medication categories.
The most serious concern is with warfarin (Coumadin), a blood thinner — CoQ10 may reduce warfarin's effectiveness and increase clot risk. Four cases of reduced warfarin protection linked to CoQ10 have been reported.
Read the full breakdown — every affected drug type, severity by severity
CoQ10 also potentially interferes with chemotherapy drugs called alkylating agents (like cyclophosphamide) used to treat cancer. Because CoQ10 has antioxidant effects, it may theoretically shield tumor cells from these treatments and reduce their activity.
Additionally, CoQ10 might lower blood pressure on its own, so combined use with blood pressure medications could cause your pressure to drop further than intended.
Additionally, CoQ10 has no documented interactions with several other medication types. Altogether, these interactions span 198 individual medications.
If you take any of these drugs or any prescription medication, use the interaction checker below with your exact medications before starting this product.

For each ingredient in Quinogel 100 mg Double Strength with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Quinogel Ubiquinol
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.
