8 Best CoQ10 Supplements 2023

CoQ10, commonly referred to as coenzyme Q10, is one of the most well-liked dietary supplements for cardiovascular health. It has also been linked in studies to regulating blood sugar, boosting fertility, preventing cancer, and even reducing migraines.

CoQ10 Supplement Market size was valued at $548.69 Million in 2020 and is projected to reach $1.15 Billion in 2028, growing at a CAGR of 9.73% from 2021 to 2028. (R)

As you age, your body produces less CoQ10. In addition, it has been discovered that statin users and patients with specific diseases, such type 2 diabetes mellitus (T2DM), have lower amounts of CoQ10. Restoring CoQ10 levels in T2DM patients may reduce oxidative stress, protect mitochondrial function, and ultimately result in better glycemic control.

CoQ10 supplements may also help atrial fibrillation (a-fib), nonalcoholic fatty liver disease (NAFLD), insulin resistance, heart failure, cancer and migraines (R).

Ubiquinol May Be More Bioavailable Than Ubiquinone

Both ubiquinol and ubiquinone are forms of CoQ10 (coenzyme Q10). Some studies showed that ubiquinol may be more bioavailable than ubiquinone. However, the study is still inconsistent.

A study aimed to compare the effectiveness between ubiquinone and ubiquinol to enhance the CoQ10 status in older men suggests that ubiquinol supplement are more effective than ubiquinone supplement.

Another study found no significant differences between ubiquinone capsules and ubiquinol capsules in the redox status of the absorbed CoQ10.

Heart rate went back into range - not immediately but absolutely back into range with an average of about 70 versus well over 100. Works well for me and will continue to take.

Great quality. A part of my healthy heart supplement regimen. Anyone taking a prescription or natural OTC statin to lower their bad cholesterol should also take a quality CoQ10 (in the form of Ubiquinol, not Ubiquinone if you're over age 30) because statins eliminate the CoQ10 produced by the body. Some doctors recommend this to their statin taking patients but most don't.

8. MitoQ Advanced CoQ10 Ubiquinol Supplement

MitoQ CoQ10

- TARGETED ANTIOXIDANT SUPPORT TO THE MITOCHONDRIA: The mitochondria is where your energy is made; MitoQ delivers targeted CoQ10 antioxidants directly into the mitochondria to help your organs perform at their best and beyond. The level of CoQ10 produced inside our mitochondria naturally declines with age. Positively charged ions in MitoQ easily pass through the mitochondria membrane, which makes CoQ10 available to perform vital functions for your health, unlike any other cellular supplement.
- NEXT-GEN ANTIOXIDANT FOR VITALITY: MitoQ is better absorbed by your cell powerhouses than regular antioxidants. MitoQ is able to pass easily through the cell wall to distribute CoQ10 directly to the sources allowing MitoQ to deliver targeted support directly to your mitochondria cells. Our innovative and proven effective method of reducing free radical damage increases the intensity of our health benefits and allows you to see proven results, sooner.
- BOOST ORGAN PERFORMANCE AND DAILY ENERGY LEVELS: 90% of your body's energy comes from the mitochondria, yet every year mitochondria produce less energy due to natural aging. This is a result of free radicals present in the body during the energy process damaging the walls of the mitochondria, which causes the cell to operate less effectively. MitoQ helps to limit free radical damage at the source, supporting your cells and building resilience by reducing the risk of oxidative stress.
- UNPARALLELED BREAKTHROUGH CELLULAR SCIENCE: MitoQ relies on advanced, patented CoQ10 technology based on two decades of research and $60 million of investments. Our ingredients have been selected and formulated to provide the highest level of bioavailability and absorption on the market.

a. Who Should Avoid Taking CoQ10?

CoQ10 has possible interaction with anticoagulants. CoQ10 may reduce the effectiveness of blood-thinning medications like warfarin (Jantoven). This could increase the risk of a blood clot.

b. What Happens if Your Coq10 Levels Are Low?

A slight CoQ10 deficiency can result in muscle weakness and fatigue. Although CoQ10 deficiency is unlikely to occur in the general population, there is a higher risk in people with particular medical problems including cancer, diabetes, or genetic abnormalities.

Studies have also shown that a lack of coenzyme Q10 can make cells more vulnerable to harm from free radicals.

c. Ubiquinone Vs Ubiquinol

The main differences between ubiquinol and ubiquinone is that ubiquinol is the reduced form of CoQ10, whereas ubiquinone is the oxidized form. Therefore, ubiquinone has more electrons than the ubiquinol. 

Ubiquinone = oxidized CoQ10 = yellow
Ubiquinol = reduced CoQ10 = white

In contrast to ubiquinone, which has a characteristic yellowish color, ubiquinol is essentially white. As soon as ubiquinol is exposed to oxygen, it transforms back into ubiquinone, which is its oxidized (and yellow) form.
