HelloPharmacist Scorecard of CoQ10 100mg by WholeHealth
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 product contains 2 active ingredients: coenzyme Q10 (100 mg) and hawthorn berry. Coenzyme Q10 is a naturally occurring compound your cells use for energy production and antioxidant defense.
Hawthorn berry is an herbal extract traditionally used for cardiovascular support. The capsule itself is made with hypromellose, an inactive ingredient.
Does it work?
Moderate evidence
Coenzyme Q10 is likely effective for treating coenzyme Q10 deficiency and is possibly effective for fibromyalgia, migraine headache, congestive heart failure, and diabetic neuropathy. Hawthorn berry has insufficient reliable evidence to rate for conditions like angina, anxiety, irregular heartbeat, hardened arteries, cardiovascular disease, or cognitive function — the science doesn't yet establish whether it works for these purposes.
How safe is it?
Well-documented data
Coenzyme Q10 is generally well tolerated by most adults. Gastrointestinal side effects like nausea, diarrhea, and heartburn occur in fewer than 1% of users; doses above 100 mg per day split may minimize these.
Headache, dizziness, insomnia, and skin itching have been reported rarely. Hawthorn is generally well tolerated in studies, but because it affects the heart and blood vessels, medical supervision is important if you have heart conditions.
The safety data for hawthorn during pregnancy advises against use. There isn't enough data on hawthorn safety while breastfeeding — check with your doctor or pharmacist for personalized advice.
Meds to double-check
Major interaction found
Before you start, double-check with your doctor or pharmacist if you take any nitrates or phosphodiesterase-5 inhibitors (Major risk of dangerous blood pressure drop), warfarin or other blood thinners, blood pressure medications, beta-blockers, calcium channel blockers, digoxin, or chemotherapy drugs. Hawthorn requires medical oversight if you have any heart condition.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This product may interest someone looking to support energy production or address a coenzyme Q10 deficiency, and whose doctor has ruled out interactions with blood thinners, heart medications, or blood pressure drugs. Anyone taking warfarin, nitroglycerin, erectile dysfunction drugs, beta-blockers, calcium channel blockers, digoxin, or chemotherapy should check their exact medications with their doctor or pharmacist before starting.
Talk it over with your own healthcare provider to make sure it's right for you.

For each ingredient in CoQ10 100mg 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.
Coenzyme 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.
Hawthorn Berry
Nitrates
Theoretically, concomitant use might cause additive coronary vasodilatory effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.
Phosphodiesterase-5 Inhibitors
Theoretically, concomitant use might result in additive vasodilation and hypotension.
Hawthorn might inhibit PDE-5 and cause vasodilation.
Anticoagulant/Antiplatelet Drugs
Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that hawthorn can inhibit platelet aggregation. However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract. However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans.
Beta-Blockers
Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.
Some evidence shows that hawthorn might lower blood pressure and heart rate.
Calcium Channel Blockers
Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.
Digoxin (Lanoxin)
Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Hawthorn appears to improve cardiac output; however, hawthorn does not appear to affect digoxin pharmacokinetics. Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels.
