Best CoQ10 Supplements for Energy & Heart Health (2025)

What is CoQ10?

Coenzyme Q10 is a nutrient your body naturally produces. It’s found in every cell and is essential for turning food into energy. The highest levels are found in the organs that require the most energy, such as the heart, liver, and kidneys.

Besides energy, CoQ10 supplement also protects cells from oxidative damage. That’s because CoQ10 has antioxidant properties. These antioxidants defend your cells from harmful free radicals that build up over time.^[1]

As you age, your natural Coenzyme Q10 levels decline. Certain medications, like statins, can lower it even more. That’s why many people choose a CoQ10 supplement to help fill the gap and support energy production, heart health, and long-term wellness.

You’ll often see two forms of Q10 supplements: ubiquinone and ubiquinol. Both can be effective, but they differ in how easily your body absorbs them.

How Do CoQ10 Supplements Work?

Coenzyme Q10 is found in nearly every cell in your body. Its main job is to help your cells produce energy in the mitochondria, the part of the cell that works like a power source. Without enough CoQ10, this energy production slows down. That can leave you feeling tired, both mentally and physically.

When you take a CoQ10 supplement, you’re giving your body more of this energy-supporting compound. It helps improve your cellular function, especially in energy-demanding organs like your heart, brain, and muscles.

In addition to energy production, Q10 supplements work as antioxidants. That means they help protect your cells from oxidative stress, which is the damage caused by free radicals. One clinical review published in the Frontiers in Neuroscience showed that CoQ10 may help reduce oxidative stress in the heart and brain, improving how well these organs function over time.^[2]

CoQ10 is also involved in supporting blood flow. Some studies suggest that it may help relax blood vessels, which supports healthy blood pressure.^[3] This is one reason why many people ask about using CoQ10 and statins together. Statins medications can lower your natural CoQ10 levels, and supplements can help restore them.

Why CoQ10 is Important

Your body depends on coenzyme Q10 for energy. Every cell you have uses it to help convert food into usable power.^[4] Your heart, liver, and kidneys need the highest amounts since they work constantly.

Beyond energy, Q10 supplements give you strong antioxidant support.^[5] They help protect your cells from oxidative stress, a process that can damage tissues and speed up aging. If your CoQ10 levels drop, you may notice more fatigue, weaker heart function, and even reduced fertility.

Taking a CoQ10 supplement helps restore balance. If you’ve been wanting to know what CoQ10 is good for, it helps with energy, heart health, and cellular protection. It’s especially important if you’re taking statins, since it may lower your natural CoQ10 levels.

According to Dr. Mehmet Oz, Cardiothoracic Surgeon and Health Expert,

Coenzyme Q10 plays a pivotal role in heart health by boosting energy production in the cells of the heart. Supplementing with CoQ10 is particularly important for those taking statins, which can deplete CoQ10 levels, potentially leading to muscle weakness and fatigue.

Different Forms of CoQ10

Different Forms of CoQ10

When choosing a CoQ10 supplement, it’s important to understand the two main forms available.

• CoQ10 Ubiquinone: This is the traditional form of coenzyme Q10. Your body must convert it into ubiquinol before it can be fully used. It’s often more affordable but may not absorb as easily for some people.
• Ubiquinol: This is the active form of CoQ10. Your body can easily absorb this form of CoQ10. This makes it very effective for people who are older or have certain health conditions.^[12]

Both forms can provide strong CoQ10 benefits, but the right one for you depends on your age, health, and absorption needs. If you’re unsure, talk with your healthcare provider before deciding on the best CoQ10 brand for your situation.

Why You Should Trust CoQ10 Supplements

Choosing a CoQ10 supplement can make a real difference in supporting your heart, energy, and general health. Decades of research highlight the many CoQ10 benefits, from protecting cells against oxidative stress to supporting cardiovascular function.

High-quality Q10 supplements are carefully tested for purity and potency. Reputable brands also use strict manufacturing standards to ensure you get exactly what’s on the label. Most of the best CoQ10 brand options are third-party tested for safety and quality assurance.

For people taking statins, these supplements can be especially helpful since statin medications may lower natural CoQ10 levels in the body. Trustworthy supplements help restore those levels effectively.
