The Best Coenzyme Q10 Supplements UK

Coenzyme Q10 (CoQ10) is a substance that occurs naturally in your body. It helps to provide your cells with the energy they need to function. Some conditions and diseases have been linked to low levels of CoQ10, so it is widely believed that supplement with it may improve your health and reduce the symptoms of some conditions.  

There is still a lot more work to be done on how effective Coenzyme Q10 supplements are, but there is growing anecdotal evidence that they may reduce pain such as headaches, increase energy and support recovery from conditions like heart disease.  

We will get you up to date on the latest studies and information and guide you through the different supplements available.  

What is Coenzyme Q10?  

Coenzyme Q10 is made in your body and stored in your cells mitochondrion. The mitochondria are the power plants of cells and deliver all the energy they need to complete the various processes that they carry out every day. As part of this process, CoQ10 protects from oxidative damage and attack from bacteria and viruses.  

Consequently, if you are deficient in CoQ10, your cells are vulnerable to several conditions like; nutritional deficiency, genetic defects, wear and tear produced by disease, conditions that attack the mitochondrion, and the effects of ageing. It is thought that your body becomes unable to provide the required levels of CoQ10 as you get older, resulting in more older people suffering from conditions that result fromCoQ10 deficiency.  

The Benefits of Taking Coenzyme Q10  

CoQ10 has the most effect when your body is already deficient. This means it may not help someone who already has enough natural levels of it, but it may provide significant benefits for someone with conditions caused by deficiency.  

It is known to be a powerful antioxidant which can reduce the damage to cells caused by free radicals. As a result, its effects are linked to ageing and the breakdown of cells over time.  

1. It may reduce the complications linked to heart conditions  

Although the current evidence is inconclusive there have been a number of studies that have shown promising links between a regular amount of CoQ10 and fewer heart-related complications. A 2014 study followed 420 people with heart failure over two years and concluded that CoQ10 “improves symptoms, and reduces major adverse cardiovascular events.”  

2. It can reduce the symptoms of headaches and migraines 

CoQ10 deficiency has been linked to increased risk of headaches and migraines. Using supplements to correct the level of CoQ10 may reduce brain inflammation and prevent migraines from occurring so regularly. One study found that the supplement, when used to treat migraine in 42 regular, suffers, “CoQ10 is efficacious and well-tolerated”.  

3. It increases muscle energy and athletic performance  

The presence of sufficient levels of CoQ10 in your body decreases the oxidative stress on the cells and mitochondria. When muscle cells are under less stress, they can work more effectively and contract efficiently, allowing for stronger and more sustained effort during exercise or day to day activity.  

4. It supports brain health  

As you age, the mitochondria in your cells begin to lose the ability to function correctly. This particularly affects the brain cells, which can die or degenerate if the mitochondria aren’t working effectively. Brains are also particularly susceptible to the oxidative damage that CoQ10 helps to protect against. As a result, CoQ10 may help keep your mind healthy, and some think that this could also slow the progression of Alzheimer’s.  

The Different Forms of CoQ10

Ubiquinone vs. Ubiquinol

Coenzyme Q10 is also known as Ubiquinone. When it is swallowed, your body converts it into its active form Ubiquinol. Most supplements supply the precursor form of Ubiquinone. However, those that provide Ubiquinol may allow a more significant amount of the finished substance to be active in your body, making the supplement more effective.  

Cis vs. trans forms of CoQ10

Most chemicals come in a mix of two forms referred to as cis and trans. These are the mirror image of each other. It most cases it makes no difference, but sometimes each version has different effects. For CoQ10 supplements, it has been found that the trans-isomers are more effective.

When CoQ10 is produced naturally via a fermentation process, the result contains 100% trans isomers which are ideal for supplementation. If the supplement is artificially synthesised the resulting substance is a mix of both cis and trans molecules.  

What to buy

For the best effect lookout for supplements made with the trans form produced from fermentation. If possible you can choose those containing Ubiquinol, but they are less readily available than Ubiquinone.  

Are there any side effects? 

The effective measure of CoQ10 is usually between 90-200mg a day taken with food to help it absorb better. Several studies have used daily amounts of up to 900mgwithout observing any severe side effects.

Occasionally it may cause some people to suffer from mild nausea, heartburn and diarrhoea. If this happens you can reduce the symptoms by spreading the supplement into smaller amounts to be taken throughout the day.
