How co-Q10 could slow the signs of ageing

From a healthy heart to healthy skin, here’s how coenzyme Q10 could help keep you in good shape.

If you’re starting to notice a few more wrinkles, or you feel like you’re slowing down, it may not be just because you’re getting older – you could also be lacking in coenzyme Q10.

What is co-Q10?

Coenzyme Q10, often shortened to co-Q10, is a nutrient that’s found in every cell of your body, particularly in heart muscle cells. It acts as an antioxidant, protecting cells against damage and playing a key role in their growth and maintenance. Co-Q10 is vital to our cells’ energy production too.

Levels of co-Q10 start to decline as we get older, so less co-Q10 means less energy. You can find co-Q10 in meat, fish, eggs and wholegrains, or in much higher levels in supplements.¹

So, what can co-Q10 do for you?

Support heart health

Co-Q10 is known to support cardiovascular health. This nutrient is found in abundance in heart muscle tissue and it’s thought low levels could lead to heart problems. A review of clinical studies published in the online BMJ journal Open Heart revealed patients with chronic heart failure had 33% lower co-Q10 levels compared with control patients.²

Co-Q10 could also be beneficial in some cases. A meta-analysis by Tulane University, New Orleans, in 2013 concluded that taking co-Q10 supplements could improve symptoms of heart failure³, while a 2003 Australian study on 120 patients reported that when combined with other nutrients, co-Q10 could aid recovery in those who’ve had heart surgery.⁴ Talk to your GP if you think co-Q10 may be helpful for you.

Co-Q10 and Alzheimer’s disease

Some studies indicate a link between co-Q10 and dementia. One trial by scientists in New York found that treatment with co-Q10 could reduce levels of oxidative stress⁵ – which plays a role in Alzheimer’s – on brain cells, while the University of Maryland Medical Centre says co-Q10 may improve oxygen flow to the brain.⁶ Oxygen deprivation is linked to some types of dementia, including Alzheimer’s disease.⁷

Reduce the appearance of wrinkles

Many factors conspire to age our skin, but there is some evidence that co-Q10 could help reduce the appearance of wrinkles. In 2005, Japanese scientists discovered that co-Q10 supplements could improve levels within the skin, a prerequisite to the reduction of wrinkles⁸, while a 2015 German trial showed that using a co-Q10 cream also boosted levels of the nutrient within the skin, providing antioxidant and anti-ageing effects.⁹

Previous research from Germany in 1999 found that a co-Q10 cream blocked the action of collagenase in the skin, an enzyme that breaks down collagen, helping to keep skin looking smooth and supple.¹⁰
