Coenzyme Q10 (vitamin Q) is a strong antioxidant that can help build the foundation needed for younger-looking skin. "Coenzyme Q10 helps protect the elastic tissue and collagen that shape your skin," explains Jessica Wu, MD, an assistant clinical professor of dermatology at the University of Southern California in Los Angeles. As we get older, our natural coenzyme Q10 levels diminish, slowing the skin's ability to rejuvenate and protect itself from damage. To build levels of the coenzyme, many find that taking a dietary supplement in addition to using topical creams yields optimal results. There's a bonus to coenzyme Q10 supplements, too — some researchers believe they aid in preventing heart disease.
All brightly coloured fruit and vegetables contain antioxidants – compounds which play a key role in protecting our bodies – but many naturally purple-coloured foods contain a certain antioxidant called anthocyanin. These are beneficial plant pigments which give fruit and veg their deep red, purple or blue hues.
While studies are ongoing, it's too early to say conclusively whether purple foods containing anthocyanins deserve to be lauded as 'superfoods' as they have been in some media reports. Previous research has linked anthocyanins to a wide variety of health claims, however, including increased longevity, cardiovascular health, cancer prevention and dementia.
