Updated 20 October 2026. HealthyHey makes the CoQ10 and ubiquinol acetate products named in this guide. The research below is explained with its sources, so you can check it yourself.
Key Takeaways
- What it is: coenzyme Q10 (CoQ10) is a compound the body makes itself and uses for energy production inside cells.
- Two forms: most supplements contain ubiquinone. Ubiquinol is the reduced form; ubiquinol acetate is a different, stabilised ester of it.
- Absorption: CoQ10 is fat-soluble and absorbed slowly, so take it with a meal that contains some fat.
- Dose: supplements usually give 100 to 200 mg a day. Follow your label.
- Research: the strongest trials were in patients under medical care. For blood pressure, a Cochrane review found no meaningful effect.
- Safety: well studied, with strong safety evidence up to 1,200 mg a day. Speak to your doctor first if you take warfarin or other regular medicines, or are pregnant or breastfeeding.
What CoQ10 Is
CoQ10 sits in the membranes of almost every cell and takes part in producing energy in the mitochondria. The body makes its own supply. Because CoQ10 is a large, fat-soluble molecule, a swallowed dose is absorbed slowly and only in part; formulations where it is dissolved in oil tend to be absorbed more readily than dry powder (Bhagavan and Chopra 2006).
CoQ10, Ubiquinol and Ubiquinol Acetate
- Ubiquinone is the form in most CoQ10 supplements and the one most studied.
- Ubiquinol is the reduced form. In a study of 12 healthy adults, four weeks of 200 mg a day raised blood CoQ10 from 0.9 to 4.3 µg/mL with ubiquinol, against 0.9 to 2.5 µg/mL with ubiquinone (Langsjoen and Langsjoen 2014; the authors run a CoQ10 testing laboratory).
- Ubiquinol acetate is a stabilised ester of ubiquinol. Cell and worm studies suggest the body converts it to ubiquinol (Micucci 2026), but we found no published human study of its absorption, so the ubiquinol results above should not be assumed to apply to it.
Black pepper extract. Some products add piperine to help absorption. In a small trial, 5 mg of piperine with 120 mg of CoQ10 gave about 30% higher blood levels after 21 days than CoQ10 alone; the single-dose and 14-day measurements did not differ significantly (Badmaev 2000; the authors worked for the company that makes BioPerine).
What the Research Shows
Most of the strong research on CoQ10 comes from patients under medical care. It tells you what CoQ10 did in that setting, not what a supplement will do for a healthy person.
- Heart failure (Q-SYMBIO, 2014): 420 patients took 100 mg three times a day or a placebo for two years alongside their usual medical care. Major heart events occurred in 15% of the CoQ10 group against 26% with placebo (Mortensen 2014). This was a medical trial; CoQ10 is not a substitute for medical care.
- Blood pressure: a Cochrane review found that CoQ10 does not have a clinically significant effect (Ho 2016).
HealthyHey CoQ10 is a health supplement, labelled to support heart health. It is not a medicine. If you have a heart condition or take regular medicines, follow your doctor's advice.
How Much CoQ10 Do People Take?
Supplements usually give 100 to 200 mg a day, and many studies used 100 to 300 mg a day. A safety review found strong evidence of safety up to 1,200 mg a day (Hathcock and Shao 2006; the authors worked for a supplement industry association). Take the amount on your label with a meal that contains some fat.
How to Choose a CoQ10 Supplement
- Form: ubiquinone, ubiquinol or ubiquinol acetate. The label should say which.
- Milligrams per capsule: check the CoQ10 per capsule and how many capsules a day the label asks for.
- Cost per 100 mg: divide the price by the total milligrams in the pack.
- Oil or powder: softgels with CoQ10 dissolved in oil tend to be absorbed more readily than dry powder; with a powder capsule, take it with a meal that contains fat.
- Black pepper extract: optional; one small trial supports 5 mg of piperine.
- Published lab reports: look for heavy-metal and microbiology results, and check what each report actually tested.
How to Compare CoQ10 Prices
Work out the cost of 100 mg of CoQ10: divide the price by the total milligrams in the pack, and compare like with like (ubiquinone with ubiquinone, ubiquinol with ubiquinol).
On healthyhey.com on 20 October 2026, HealthyHey CoQ10 with Black Pepper Extract costs ₹752 for 60 capsules of 100 mg (₹12.53 per 100 mg), ₹939 for 60 of 120 mg (₹13.04) and ₹1,089 for 60 of 200 mg (₹9.08). HealthyHey Ubiquinol Acetate costs ₹1,699 for 60 capsules of 100 mg (₹28.32 per 100 mg of ubiquinol acetate).
HealthyHey CoQ10 and Ubiquinol Acetate
- CoQ10 with Black Pepper Extract (label): 100 mg, 120 mg or 200 mg CoQ10 with 5 mg black pepper extract (BioPerine) per vegetarian capsule, 60 capsules. One capsule a day with a meal. Labelled to support heart health. The label's directions say to use it for up to 30 days, then take a break of 1 to 2 weeks before resuming, or follow a healthcare professional's advice.
- Ubiquinol Acetate (label): 100 mg ubiquinol acetate with 2 mg black pepper extract (BioPerine) per vegetarian capsule, 60 capsules.
- Lab reports: CoQ10 100 mg (Avon Food Lab, NABL TC-11151, 2026: lead 0.16 mg/kg, arsenic below 0.05 mg/kg; Salmonella and Listeria absent in 25 g), CoQ10 120 mg (Avon, 2026: lead and arsenic below 0.05 mg/kg), CoQ10 200 mg (Accurate Universal Laboratories, 2024: lead and arsenic below 0.05 mg/kg) and Ubiquinol Acetate (Avon, 2025–2026: lead and arsenic below 0.05 mg/kg). None of these reports measures the CoQ10 or ubiquinol content.
Who Should Be Careful With CoQ10
- Stomach upset: mild nausea or an upset stomach are the most common complaints; taking CoQ10 with food can help.
- Warfarin: case reports have described a weaker warfarin effect, although a small trial at 100 mg a day found no change (Engelsen 2002). If you take warfarin, ask your doctor first.
- Other regular medicines: speak to your doctor before starting.
- Pregnancy, breastfeeding and under 18: speak to a doctor before use.
Frequently Asked Questions
What is the difference between CoQ10 and ubiquinol?
They are two forms of the same compound. Most supplements contain ubiquinone, the oxidised form; ubiquinol is the reduced form. The body converts one into the other. In one small study, 200 mg a day of ubiquinol raised blood CoQ10 more than the same dose of ubiquinone over four weeks.
Is ubiquinol acetate the same as ubiquinol?
No. Ubiquinol acetate is a stabilised ester of ubiquinol. Lab and animal studies suggest the body converts it to ubiquinol, but we found no published human study of how well it is absorbed.
How much CoQ10 do people take?
Supplements usually give 100 to 200 mg a day, and many studies used 100 to 300 mg a day. Take the amount on your label, and ask your doctor before going higher.
When should I take CoQ10?
With a meal that contains some fat, because CoQ10 is fat-soluble and is absorbed slowly. Follow the directions on your label.
Why is black pepper extract added to CoQ10?
Black pepper extract (piperine) is added to help absorption. In one small trial, 5 mg of piperine with 120 mg of CoQ10 gave about 30% higher blood levels after 21 days than CoQ10 alone, though not at 14 days.
Can I take CoQ10 with my medicines?
Speak to your doctor first, especially if you take a blood thinner such as warfarin: CoQ10 has been reported to change its effect in some people.
Is CoQ10 safe to take every day?
A safety review found strong evidence of safety at intakes up to 1,200 mg a day. Mild stomach upset is the most common complaint. Follow your label, and check with your doctor if you are pregnant, breastfeeding or on regular medication.
Our Recommendation
Decide the form first: ubiquinone is the most studied and usually the cheapest per milligram; ubiquinol raised blood levels more in a small study; ubiquinol acetate has no human absorption data yet. Then compare the milligrams per capsule and the cost per 100 mg, and take it with a meal that contains fat. If you take warfarin or other regular medicines, talk to your doctor before starting CoQ10.
