    As seen in the media: Leading scientist reveals CurraNZ is THE best performance enhancer in sport

    on May 30, 2020

    THE celebrated international research on CurraNZ® has been making major headlines in New Zealand this week.

    A new peer-reviewed meta-analysis has confirmed what we’ve known for a while: Our CurraNZ New Zealand blackcurrant extract is a world-beater for sports performance.

    The authors from New Zealand Plant and Food Research Institute reviewed the University of Chichester studies and concluded that Curranz is the ‘best legal performance enhancer on offer’.

    Their review focused on nine studies - eight on CurraNZ – that underpin the international scientific evidence to date.

    They concluded our unique extract can significantly improve running, cycling and climbing performance in athletes to a ‘significant degree’.

    The scientists calculated blackcurrant’s effect by a standardised mean percent effect on performance equates to 0.45 – which exceeds that of caffeine (0.41). Until now, caffeine has ‘long been touted as the most potent legal ergogenic food or supplement available’ - until CurraNZ.


    Elite British athletes such as 2020 British Indoor 1500m Champion George Mills (pictured left) swear by CurraNZ.

    In a news article announcing the research, one of the authors, Professor Roger Hurst, (pictured, top), says CurraNZ studies show New Zealand blackcurrant extract could be the ‘difference between winning a gold and silver medal at Olympic level’. While we haven’t performed that piece of research in Olympic athletes yet, the signs are promising.

    CurraNZ is the official supplier to High Performance Sport New Zealand and was used by many British Olympic athletes when the team won their biggest-ever haul of gold medals at the Rio Olympics. 

    The scientist's claims are all true: World-class athletes have been using CurraNZ for many years to support their performance, but it isn’t a one-trick pony, with potent muscle recovery and immunity properties too.

    The study, The Effect of New Zealand Blackcurrant on Sport Performance and Related Biomarkers: A Systematic Review and Meta-Analysis was published in the Journal of the International Society of Sports Nutrition,


    Only Enzans®, found in CurraNZ®, delivers evidence-based health and sports properties

    CurraNZ® contains a proprietary blend of New Zealand blackcurrant anthocyanins, which are characterized by Enzans®, key identifiers of the high-potency bioactives that deliver the unique and outstanding properties of our product.

    Of the blackcurrant products available in New Zealand, only the CurraNZ® Enzans® have been proven in an international program of peer-reviewed health and sports research. 

    Be wary of copycat products – 99% of blackcurrant extracts do not meet our exacting standards due to the high variation in the nutritional quality and genetic make-up of blackcurrants and production methods that influence its efficacy and quality.
