At the first sign of illness, chances are many of us reach for the vitamin C. It’s long been a popular way to support immunity, thanks to its well-documented antioxidant activity.
What many people don’t realise is that nature has generously provided us with another, even more powerful, natural antioxidant: olive leaf extract. The humble Olive has been staple of the Mediterranean diet for centuries – and believed to play a part in the incredible longevity of the region’s inhabitants – and olive leaf extract is rich in antioxidant polyphenols and other natural flavonoids.
Keep reading to see how olive leaf extract measures up against several other well known antioxidants used to support immunity, including Vitamin C...
As you can see in the chart above, olive leaf extract contains around five times more antioxidant power than Vitamin C, or in other words, a whopping 400% more!¹
That’s because olive leaf extract is high in polyphenols and other natural, plant-based flavonoids. The ‘hero polyphenol’ found in abundance in fresh picked olive leaf extract is antioxidant-rich oleuropein, a naturally occurring plant compound which is thought to be largely responsible for olive leaf extract’s health-giving properties.
Like vitamin C, olive leaf extract’s potent plant polyphenols, including oleuropein, have powerful antioxidant activity that can help to protect against free radicals produced during oxidative stress or inflammation.³,⁴ Scientific studies have shown that olive leaf extract supports immunity, general wellbeing and even cardiovascular health, helping to support maintenance of normal blood pressure and normal blood sugar levels. ⁵⁻⁷
A 2005 study out of Australia’s Southern Cross University compared our fresh olive leaf extract to dried leaf, and also to other popular antioxidant-rich foods and supplements, including green tea extract, grape seed extract and vitamin C.
As the graphic above shows, fresh olive leaf extract had the highest antioxidant activity – it’s nearly twice as potent as green tea extract, and around 10 times as powerful as grape seed extract.²
What’s more, when it comes to fresh olive leaf versus dried, there’s no comparison. Made from freshly-picked leaves, Olive Life’s antioxidant activity is over 6 times higher in antioxidant activity than dried olive leaf.² This demonstrates that, as with so many things in nature, fresh is generally best.
Why is it so much higher? We believe it’s the combination of fresh-pickedᵀᴹ leaves and our gentle water extraction method, which allows our olive leaf extract to retain optimal levels of antioxidant and protective compounds found naturally in the original fresh leaf.
Olive trees have extremely powerful defence systems, enabling them to live for centuries. We grow Olea europaea olive trees (found extensively in the Mediterranean) because they’re rich in polyphenols - the naturally-occuring plant compounds that help to protect trees from disease, pests, droughts and extremes of hot and cold.
Olive leaf extract is our way of passing on nature’s incredible properties to humans in a simple daily dose – so we can also enjoy the olive tree’s renowned protective benefits.
The good news is that one daily dose of Olive Life is a lot easier to take than the equivalent amount of vitamin C! So why not try our olive leaf extract for yourself, and start reaping the rewards of this natural ‘super-antioxidant’?
