Coenzyme Q10, commonly known as CoQ10, is a well-known supplement praised for its role in supporting heart health and overall vitality. Beyond cardiovascular benefits, research suggests it may also aid in stabilising blood sugar levels, support skin health, help reduce the frequency of migraines, and even offer protective effects against certain diseases.
While not every claim has equal scientific backing, there’s growing evidence that CoQ10 supplementation can make a noticeable difference for many people. With so many options available on the market, choosing the right CoQ10 supplement one that’s both safe and effective, can be overwhelming.
In this guide, we’ll break down what CoQ10 is, how it works, and highlight some of the top supplement brands worth considering.
Our Criteria for Choosing the Best CoQ10 Supplements
Our primary focus was on effectiveness—specifically, the strength of the formula, the quality of ingredients, and whether the dosage aligns with current research. Right behind that came pricing, since CoQ10 products can vary widely in cost, and value for money matters. Next, we looked at safety, which is generally consistent across most CoQ10 supplements but still worth confirming for peace of mind. Lastly, we considered customer experience, how easy it was to order, shipping speed, and how responsive the brand was, because the buying process should be just as smooth as the supplement itself.

What is CoQ10?
Your body makes a natural antioxidant called Coenzyme Q10, or CoQ10 for short. It's really important for giving your cells energy – think of it like the spark plug for your body's engine. You can find CoQ10 in almost all of your cells (about 95%), with lots of it in important organs like your brain, liver, heart, and kidneys. As you get older, your body doesn't make as much CoQ10, which is why some people consider taking supplements, even if they don't have a specific problem.

How CoQ10 Supplements Work
Exploring the potential benefits supported by research.
Heart health
Heart health is one of the most common reasons people take CoQ10, and there is a lot of science to back up their choice. In one compelling study of more than 400 participants over two years, there was a 15% difference in the occurrence of major adverse cardiovascular events.
Liver health
In a study of subjects with nonalcoholic fatty liver disease, a 100mg dose of CoQ10 resulted in a significant reduction in markers associated with inflammation and tumor development over 12 weeks.
Skin quality
In a relatively small-scale study of 33 participants, 150mg of CoQ10 successfully reduced wrinkles and other signs of aging, though it didn't seem to affect dermal hydration.
Blood sugar control
A meta-analysis examining multiple studies indicated that dosages between 100-200mg of CoQ10 showed promise in influencing blood sugar levels. While more research is often warranted, these findings offer a glimpse into a possible connection.
Are CoQ10 supplements safe?
Generally, CoQ10 appears to be a well-received supplement, with most research indicating a low incidence of negative effects across various study groups. When individuals did experience issues, they were typically minor and temporary, potentially involving mild digestive discomfort such as abdominal pain, nausea, or changes in appetite and bowel habits.Less frequently reported were effects like sleep disturbances, tiredness, headaches, or slight mood alterations. Even at relatively high daily intakes, such as 750mg in studies and up to 600mg in available supplements, significant safety concerns haven't been widely observed.
However, specific life stages like pregnancy and breastfeeding lack sufficient safety data, prompting a cautious recommendation to avoid CoQ10 during these times. As with any dietary addition, consulting a healthcare professional before starting CoQ10 is always advised.
