Scientifically validated by New Zealand's World Class  Laboratories. 

At GreenKiwi Supplements we are proud of the products which we produce. We partner with leading New Zealand Laboratories to guarantee efficacy and quality. Extensively researching our extraction processes to ensure minimal bioactive molecular disturbance from our fresh olive leaf, formulating and backing claims with global independent published scientific evidence, offering unique natural health products that deliver support for your health, when and where you need it.


Oleuropein is an extensively researched bio active compound naturally found in the Olive Leaf.


Independent science has shown a direct correlation between Oleuropein and a healthy cardiovascular system, due to its powerful antioxidant properties.


While Oleuropein is naturally occurring in olive leaves it's part of the polyphenolic family of synergistic antioxidants, meaning for Oleuropein to offer its synergistic properties it must not be standardised, or heat treated.


This is why GreenKiwi OliveXtract is raw processed, and third party laboratory tested for Oleuropein concentration by one of New Zealand's leading laboratory and research institutes. From these exact batch test results we formulate each bottle we produce, meaning OliveXtract is free from Oleuropein standardisation or heat damage, offering science backed assurance of powerful, synergistic antioxidant activity.

Hydroxytyrosol is a naturally occurring bioactive compound found in olive leaves. 1 of 12 compounds in the 'Polyphenol family' naturally present in the olive leaf, Hydroxytyrosol is the most powerful natural antioxidant compound on the planet. With an ORAC score of 68,000+ it's 3X more powerful the COQ10 in terms of its antioxidant capacity/effectiveness, and is small enough to reach the blood-brain barrier.
