10 Best CoQ10 Supplements Fully Researched and Compared

last updated Jan 30, 2019
Our simultaneously delicate and masterful bodies often require a bit more than even the best-laid lifestyle plan can provide. Certain vitamins and nutritional supplements go a long way in ensuring physiological balance even when the unexpected interferes with our fitness, nutrition, and other goals. Of these, Coenzyme q10 is a major player. Found in all of our cells, and synthesized by the body, CoQ10 is largely responsible for producing energy. Additionally, it’s a megastar antioxidant which protects from harmful molecules that can be damaging. The “great recycler”, CoQ10 even reuses Vitamin C and E which means enhanced effects. With so many CoQ10 supplements available, it’s critical to find one that’s compatible with your own diet, health and even lifestyle – including budget.

Pros:

Third party tested and verified to be pure

Choose your own dose

Reputable company

Cons:

Some users received a product that had been exposed to moisture

Don't be fooled, just because this company sells their products in bulk form doesn't mean they aren't good. In fact, they are consistently one of the highest rated supplement companies. For a lot of people, the most appropriate dose of CoQ10 is extremely small, smaller in fact than what comes in most pills or capsules. So being able to use just a little bit makes this a convenient product to take because you can choose your own dose.

Read more

Effectiveness

Users found this to work well in improving their energy and heart health. Several reviewers also noted that it helped improve their mental functions as well. It contains just the supplement powder with no additives or fillers, which is great, however, you may want to take it with black pepper extract, coconut oil, or another oil that will assist your body in fully absorbing and using the supplement.

Product Purity

This company uses third-party testing for all their products. This one is no exception and it has been found to be free of additives or anything other than CoQ10.

Use

This one is great for people who want to increase their energy especially as they age. Those with heart conditions will also experience good benefits, although you should talk with your doctor before starting to take it, especially if you're already taking statins to help control your cholesterol.

Value

Despite it coming in bulk form, this one is a little more expensive than other options. However, being able to take just a small and appropriate dose means it may last longer than options that come in pill or capsule form.

Effectiveness

The added bioperine, naturally sourced from black pepper extract, helps your body absorb this supplement and get the most out of it. Several reviewers noted how well it worked for them, especially in helping with heart conditions and a drop in energy levels due to aging.

Product Purity

This one is made through a natural fermentation process. It has added soybean oil to help with absorption, although this does make it less natural than other options.

It's great for those who are on statins to help control their cholesterol. Anyone looking for a natural boost in energy, brain function, and overall better health outcomes will also enjoy its benefits.

Value

One of the most expensive products on our list. As usual you get what you pay for and we didn't find many complaints about the price.

Pros:

Ultra pure, well researched and sought after ingredients from across the world

We love the addition of botanicals for their medicinal value

Zero artificial preservatives

No nuts/allergy safe

Cons:

Pricier

Lower mg’s of CoQ10

Formulated with pure sources gathered worldwide, the Thorne Research Choleast with CoQ10 is a union of pure botanicals, science-driven formulation, minerals, and a highly absorbable Coenzyme Q10. The perfect supplement for enhanced wellness.

Read more

Absorption

This capsule both easy to swallow and boasts only pure ingredients, to include any coverings or lining associated with the capsule, itself. Even the preservatives and sweeteners are derived from botanicals or other natural sources so that your safety and best health is ensured. Simple, faster absorption results from this integrity.

Formulation

In each dose, the Thorne formulation includes 200 mg of Magnesium, 90 mg of Potassium Citrate, 900 mg of Taurine, the flowering tops of Hawthorn extract - 350 mg, and 45 mg of coenzyme Q10. Hypromellose (from cellulose), Leucine and Silicon Dioxide are also included. The combination of minerals and other thoughtful ingredients enhance this heart-healthy version making it an excellent selection for those looking for CoQ10 with the added benefits of magnesium and botanicals.

Dose/Safety

Some botanical ingredients can also cause blood thinning so it’s important to discuss this formulation with a physician. The lower CoQ10 (45 mg) is suitable for most, taken daily.

Cost and Value

Slightly higher price, but very fair when considering the conglomeration of pure botanicals, minerals, and non-synthetic preservatives.

The softgel, which is comprised in part of water-soluble glycerin, absorbs faster without compromising the stomach or digestion. The Ubidecarenone CoQ10 also works fast and converts easily to ubiquinol - the reduced form the body makes naturally.

Formulation

A light list of ingredients includes soybean oil, purified water, glycerin and gelatin combined with Ubidecarenone to assist in digestion and absorption without compromising the purity or the integrity of this CoQ10 version.

Dose/Safety

Serving size is recommended at one dose per day, each dose containing 100 mg of CoQ10. It is recommended that additional dosage is verified first with a medical doctor, especially for those interested in heart tissue repair or boosting weakened immune systems.

Cons:

Absorption

Using a high-grade CoQ10 assisted with tocopherols (TCP) to help methylate, this soft-sided capsule is easy to swallow and absorb. No additional soluble fillers are necessary so the stomach is as happy as the skin, eyes, heart, and immunity!

We love the “robust” formulation which will definitely help to keep you healthy! The unique selection of tocopherols to assist in methylation and absorption also boast Vitamin E activity which further increases skin health. Add gelatin and purified water for better preservation with higher solubility.

Dose/Safety

Because this supplement is free of sugar, salt, starch, yeast, GMO’s, dairy and fish products, it is unlikely to interfere with any relatable food allergies or medical contraindications. The recommended dose is 1-3 100 mg softgels per day (not to be taken at once) with meals.

the supplement is extremely budget friendly. Typically, the higher dose is more preferable for older adults or those with cardiovascular conditions.

Quite affordable offering great value for money

Cons:

60 capsules equates to a two month supply, which is less than some contenders

Simple ingredients and a powerful version of CoQ10 fuse to create a powerhouse formulation for improved heart health, fabulous skin, and best-ever energy!

Read more

Absorption

Made from pure Ubidecarenone (the official U.S. name for Ubiquinone, the generic label), this oxidized version of CoQ10 digests easily with no disruption to the stomach while still providing quick absorption. This high-quality hydrosoluble moves specifically to the mitochondria and enhances energy while boosting immunity and even skin health.

Formulation

Formulated with a powder-within-capsule for easy swallowing, the Ivy Naturals CoQ10 also keeps it easy on ingredients, listing the Ubidecarenone as its primary ingredient, followed only by glycerine, gelatin, purified water and soy bean oil for smooth and healthy absorption and benefits.

Dose/Safety

100 mg per day is the recommended dose. Children under the age of 18 should not take without medical supervision. Those with allergies or medication reactions to soy also need to consult with a physician.

Cost and Value

Criteria Used for Evaluation

Effectiveness

It’s vital that users consider the delivery system used to get this nutrient into the body. First, there are two types of this supplement: ubiquinone and ubiquinol. Ultimately, whichever type you choose, the body intelligently converts one to the other, depending upon which is naturally lacking. Nevertheless, each type initially has its benefits with regard to delivery. Ubiquinone is oxidized, which also means its an electron acceptor and considered a stable form of CoQ10. Ubiquinol is a reduced form, a form understood to be an electron donor. It is less stable but also serves as an excellent antioxidant, and in some studies has shown to absorb faster while resisting harmful free radicals. In some part, understanding your individual goals will help you to decide upon one that is oxidized or one that is a preferred antioxidant; keeping in mind that both work together in the body, and ultimately “balance”.
It is also important to take the coenzyme q10 with meals. Not only can this help the stomach stay calmer after ingestion, but because it works with cell parts that convert food to energy, food is necessary to assist in optimum absorption throughout the body.
Softgels are typically easier and faster to absorb than powder capsules. However, note the ingredients before making a final selection; a powder version of fish oil will absorb well because it’s fat soluble. And be sure to check out the shell’s ingredients (no need for preservatives, yeast, wheat or synthetic materials).

Product Purity

Be sure to check out the list of ingredients associated with any formulation of this product. It is totally unnecessary to combine yeast, wheat, sugars or any type of synthetic preservative with your blend. On the other hand, certain combinations can assist with absorption. For example, Bioperine, a patented extract derived from black pepper fruits (Piper nigrum) is used as a bioavailability enhancer. Generally, when used in combination with other nutrients, it will increase absorption by 30% or more!
Selecting a product that includes Olive or Fish Oil can also help the supplement to absorb and act more efficiently. Gelatin, purified water or glycerin are each composed of a healthy blend, typically. While they assist in filling and preserving, they are not synthetic and pose no harm to the body.
Many brands have organic options available. Knowing that the list of ingredients is mindfully produced means even safer digestion and impact on the body and cells.

Use

There is no “one correct dose” when it comes to your CoQ10. Though typical doses range from 45 milligrams to 1200 milligrams (for adults). At higher doses, expect to split between several meals and times each day. The most common dose is 100 – 200 milligrams per day. Physicians recommend that children up to the age of 18 receive a medical consultation prior to beginning this supplement and that usually goes for adults taking more than 100-200 mg’s per day, also. It is imperative to examine additional ingredients to ensure zero contraindications with other prescribed medications or even supplements and food allergies.

Value

This too can range as wide as the doses! However, it is possible to find “fair” pricing – our top ten contenders vary some but are each affordable. Look for the ratio of capsules to price. Some may seem pricier, but may provide a four or even six month supply! It’s also important to note the milligrams when making price point comparisons.

Where is it in the body?

CoQ10 is present in every cell of the body but is found in higher concentrations in organs such as the liver, kidneys, and heart; wherever there is higher energy use. The body produces it naturally in these places. However as you age its natural production decreases which is why it's an important supplement to take, especially for those with heart conditions.

Check with your doctor

There is varying science about the positive effects and benefits of this type of supplement, of course, consult with your doctor before adding this to your lifestyle. In fact, we recommend talking to your doctor about any supplements you are thinking about taking, especially if you're on medications that it may have an adverse interaction with. In the end however, remember that the modern medical system often functions by treating the symptoms and not the causes of disease, and that natural supplements can be a great way to keep yourself healthy without resorting to traditional medications.

Other Factors to Consider

Ease of Use

How much CoQ10 you decide to add to your diet depends in part on the type of diet you already have. For example, excellent sources of this nutrient are found in tuna, mackerel, and salmon (and most other cold water fish). It’s also readily available in oils and some meats. If you find yourself lacking in these food groups, then consider a higher dose or possibly taking it more than once a day. If your diet is rich in these foods, a lower dose will likely suffice. Again, checking with your doctor to be sure is always best!
Second, if your lifestyle is active and you’re interested in a supplement to assist in fitness recovery or a slight boost in energy, consider a lower dose with a bioavailable delivery system that helps the nutrient to synthesize fast.
If your lifestyle is less active, a larger dose can help you build heart strength, increase higher energy and protect immunity so that you can ultimately feel healthier and achieve a new level of activity.

Application

Choose a supplement that compliments your health needs with its unique design. Water and fat-soluble coenzyme Q10 blends can help to repair damaged heart tissue – so look for brands that are both. Some research has shown that with just-right delivery, this enzyme might even replace tough-on-the-body statins!
For a tougher immunity, look for blends with additional vitamins, especially Vitamin E and C. And spread dosage out throughout each day for more consistency within the body.

Bottom Line

CoQ10 has no known serious side effects; however, medications have been known to negatively impact its levels. If you are taking a specific milligram for certain conditions, then be aware of how other medicines may be altering that level. It is imperative to discuss this with your doctor to be sure that your nutrient is able to operate optimally. It’s also important to be aware of other ingredients in your blend. Sunflower oil may be a wrong fit for those with nut allergies, bovine gelatin is something for vegetarians to consider, and certain extracts may negatively interact with not only medicines but possibly other supplements.

Frequently Asked Questions

q: What happens if my CoQ10 levels are low?
a:

It is common to experience low energy with low levels of CoQ10, and also more joint and muscle cramping. Most importantly, low levels impact the body’s production of cellular injury which results in a host of potential health risks, to include serious heart problems.

q: Is there a test to see if I have low levels of CoQ10?
a:

Yes. Many chain laboratories test for low levels of CoQ10. However, the test measures levels found in the blood, not within the heart tissue. If blood tests exhibit lower levels, this can be used by your physician to at least in part determine if heart (or other conditions) are being negatively affected by the low levels. This can also help your doctor to make important decisions about statins and other drugs you may use to “treat” conditions that at least in part can be rectified by stabilizing coenzyme Q10.

q: Why is CoQ10 so necessary?
a:

Because of its natural occurrence in our cells, when it begins to dissipate our body doesn’t operate as well. Something as “simple” as aging can cause this. High levels of CoQ10 are found in the tissues of organs that are vital to our survival – the heart and liver, for example. Operating as a free radical scavenger and fat metabolizer and vital to the production of crucial enzymes means that the redelivery can mean an increase in better health and age prevention.

q: Is there a best way to take CoQ10?
a:

The best way to deliver this nutrient to your body depends upon your body, individually. For example, if you have nut allergies, avoid products with sunflower. If you are a vegan, vegetarian or Kosher avoid gelatin comprised of bovine. Softgels and ingredients like olive oil make digestion simple and easy on the stomach, but some prefer smaller capsules without oils. Know who you are, and how your other medications and lifestyle/diet might contradict or complement a specific formulation for best results.

q: When is a good age to begin taking CoQ10?
a:

As the old adage explains, ‘it’s never too late…’ to begin! But it can be too early. For those under the age of 18, it is important to discuss taking any form of CoQ10 with your physician first. It is often typical for those between 18-40 to take a lesser dose than older adults, with the exception of those suffering from specific health conditions that may require alternative doses.

q: How and when do I take CoQ10?
a:

It can be taken alone, with water or with a meal; however, it is recommended that it be taken with meals, particularly those with fats to help with digestion and absorption. It can be taken with oils used in salads as dressing, fish/and fish oils, coconut or flax seed oil. Most importantly, when you’ve selected your preferred brand of CoQ10, refer first to the specific instructions provided as part of its own label.

q: What are the side effects of taking CoQ10?
a:

CoQ10 will not cause serious side effects or issues for most people, but if you do have a heart condition, you should not be taking dietary supplements, except for under the supervision of your doctor. You should also avoid taking CoQ10, if you are on anticoagulant medicaments, like Warfarin, as this can affect the drug. Please consult your doctor before taking the CoQ10, if you are on any prescription medicine.
