400% More Powerful than Vitamin C

Our fresh-picked Olive Leaf Extract has 400% more antioxidant power than the equivalent amount of Vitamin C and is far more powerful than the many Noni, Goji, Mangosteen and Acai ‘super-juices’.

What are antioxidants?

Antioxidants play an essential role in the body as they quench free radicals. By damaging healthy cells, free radicals can leave the body vulnerable to advanced ageing, cardiovascular problems and degenerative diseases.

Free radicals can be caused by many factors including sun exposure, pollution, stress, poor diet, alcohol and cigarette smoke.

Research conducted at Australia’s Southern Cross University (SCU) has
identified the olive leaf as the most powerful, free radical-scavenging
antioxidant of 55 medicinal herbs.

Free Radical Hunter


A free radical is an unstable oxygen molecule with an unpaired electron.

Olive Leaf Australia’s extracts are scientifically proven to contain more than 20 polyphenolic antioxidants which, individually, each quench specific groups of free radicals, and in synergy, form one of the most powerful naturally-occurring free radical hunters known.

Total Antioxidant Capacity of Olive Leaf Australia’s Extract

The Oxygen Radical Absorbance Capacity, better known as ‘ORAC’ and the Total Antioxidant Capacity (TAC) are the internationally-recognized laboratory techniques that measure the antioxidant effect of foods, chemicals and natural compounds. The tests measure a product’s antioxidant ability to neutralize free radicals and potentially mitigate degenerative diseases, cell degradation and ageing.

Polyphenolic antioxidants

Polyphenolic antioxidants can help to prevent the signs of ageing, reduce cell degradation and assist in the prevention of a number of degenerative diseases. Polyphenolic antioxidants are best known in the scientific and medical communities for their ability to neutralize free radicals.

The most studied polyphenolic antioxidants in Olive Leaf Australia’s Extract are oleuropein, hydroxytyrosol, caffeic acid, verbascoside and tyrosol.
