Best CoQ10: Qunol vs. Nature Made vs. Kirkland vs. Doctor's Best?

Best CoQ10: Qunol vs. Nature Made vs. Kirkland vs. Doctor's Best?

    Studies show that when we are young, our bodies synthesize CoQ10 well, converting it readily to Ubiquinol. But as we get older, the body's ability to convert CoQ10 to Ubiquinol diminishes. This means that as we age, CoQ10 supplements may become less effective, which is one reason we don't feel as energetic as we did in our youth. Taking a CoQ10 supplement is an effective strategy to increase your supply and regain your lost energy levels. Qunol, Nature Made, Kirkland, and Doctor's Best are popular CoQ10 brands, but which one is better? How do you know which one is best for you? Here we reviewed these four brands to help you find the best CoQ10 supplements for your daily life, evaluated quality, pros & cons, and prices and determined which one is best for you.

About CoQ10 

CoQ10 is a potent antioxidant that plays a role in many pathways in the body, most notably the energy-producing pathway in mitochondria (also known as the powerhouses of your cells). CoQ10 is found in every cell in your body, but it’s mostly concentrated in organs and tissues that require the most energy production, such as your heart, liver, brain, kidneys, and lungs. It’s therefore important for their optimal function as well as the function of your reproductive system, supporting fertility and healthy pregnancy. CoQ10 is naturally produced by the body, but production declines with age. CoQ10 levels are also depleted by taking statin medications for cholesterol, making it even more important for these people to take it. 

There are two forms of CoQ10: 

1. Ubiquinol 

Ubiquinone is the oxidized form, which is converted into the reduced form called ubiquinol in the body. Ubiquinone is fat-soluble and not very absorbable on its own, so to aid in absorption, many companies add an orange peel extract called -limonene to serve as an emulsifier. 

2. Ubiquinone

On the other hand, ubiquinol is water-soluble, and therefore is much more easily absorbed into the bloodstream. Ubiquinol is up to eight times more absorbable than ubiquinone and has shown to be more effective for managing health issues such as heart failure and fibromyalgia. On top of its superior absorption, some ubiquinol products are combined with an ingredient called shilajit , which even further increases the efficiency of energy production. The form of CoQ10 that’s best to take is ubiquinol (optimally with shilajit). 
Ubiquinol is the superior form of CoQ10, so we encourage you to check the supplement facts label on the product to ensure you know what form you’re getting. If the form of CoQ10 is not indicated on the product’s label, it’s most likely the less absorbable ubiquinone form. However, it’s still a good idea to contact the company for this information.

Who Should Take CoQ10?

The true way to know what form and dose works best for you is by doing a blood test . 

  • Based on research, it appears that the blood level that adults should aim for is 3-7 mcg/mL. 

  • Most people need at least 50 mg of CoQ10 and some need up to 200 mg or more per day to keep their blood levels in range. 

  • The most common dose for healthy individuals is 100 mg, while smokers and/or statin takers around 200-400 mg per day. 

Note: CoQ10 supplements come in various forms, and you can find them as pills, chewable tablets, wafers, syrups, or an intravenous (IV) solution. Even though they’re generally considered safe, there are some people who should abstain from taking CoQ10 supplements. You should not take this supplement if pregnant, breastfeeding, or under age 18. Use with caution if you have diabetes, liver failure, kidney disease, or heart failure without the consent of a physician.

Qunol CoQ10

Qunol Liquid CoQ10 is ideal for anyone who wants to avoid the hassle of swallowing pills or the added ingredients that come from softgels. The company also offers CoQ10 gummies. Unfortunately, neither the gummies nor the liquid is available in a 200mg dose — both come in 100mg doses only. You could always double up on the amount yourself, but that would get expensive quickly.

For the most part, Qunol uses Kaneka ubiquinol in their CoQ10 supplements, but some contain ubiquinone. Some of those ubiquinol options come with a 250mg dose of omega-3s, which are an ideal lipid partner for CoQ10. They’ll aid in absorption while also providing their own health benefits.

Here’s a look at Qunol’s various CoQ10 products:

1. Ultra CoQ10, 100 mg, 120 Count

2. Mega Ubiquinol CoQ10, 100 mg, 100 Count

3. Liquid CoQ10, 100mg

4. Ubiquinol Extra Strength, 200 mg, 60 Count

Kirkland Reviews

Costco's Kirkland Signature brands are well-known for their high quality and low cost. Nationally-known companies like Starbucks, Duracell, and Reynolds are among the manufacturers for Kirkland products. Kirkland now makes up over 30% of Costco's total revenue. You can buy Kirkland Signature products in various categories at Costco, including clothing, grocery, health & beauty, household & cleaning, organic, home & kitchen, diapers & baby, and pet food & supplies. But they only sell one CoQ10, which is Kirkland Signature CoQ10 300 mg.


Pros & Cons  

  • Low price for a high dose

  • Made with bovine gelatin

  • No artificial colors

  • Only available to Costco members

  • Gluten- and lactose-free

  • Uses soybean oil as its lipid

  • USP verified

  • No subscripition

  • Free shipping 

  • Only available as softgels

Kirkland CoQ10 

Kirkland Signature CoQ10 supplement comes in a 300mg dose, which is unusual compared to most other companies’ offerings. It’s a little more than the most common dose — 200mg — without increasing side effect risks significantly. Still, you should talk to your doctor before beginning a regimen of this or any CoQ10 supplement.

Kirkland delivers one of the best deals around (100 Softgels for $24.99). They’re also tied for the lowest cost per gram of CoQ10. Unfortunately, they achieve this by using some inexpensive ingredients like soybean oil to cut costs.

Kirkland products are also sold exclusively to Costco members, so you’d have to calculate for the cost of membership. That said, Costco is known for having particularly liberal return policies. And with 100 softgels in a bottle, you can try this supplement for over two months and likely face no issues getting your money back if you’re not satisfied.
