BLACKCURRANT best aid to improve performance

BLACKCURRANT has been becoming popular as a performance and recovery supplement for a few years now, and a new research review has revealed it is the best ergogenic aid available for improving athletic performance.


The scientists from New Zealand Plant and Food Research Institute and Auckland University reviewed the sports data on New Zealand blackcurrant, crunched the numbers and found it to be even more effective than caffeine – previously considered the best.

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

They concluded the berry extract can significantly improve running (11%), cycling (2.4%) and climbing performance (15%) in athletes to a ‘significant degree’.

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




Why blackcurrants? A polyphenol-rich berry, their bioactives have antioxidant, anti-inflammatory and blood flow-promoting properties, and until 2014, little was known about their potential as a performance and recovery aid.

In the last six years, over 20 studies have been published on the sport and health benefits of the New Zealand blackcurrant extract, with many ‘world first’ discoveries revealing the berry:

-        offers unprecedented effects on fat oxidation, with one week’s loading delivering increases usually seen after four weeks of training

-        increases tissue oxygen uptake and recovery times up to 38%

-        doesn’t blunt adaptations to exercise, but in fact primes the body’s responses to training

-        Increases main arterial blood flow up to 35% during exercise

-        Keeps blood vessels healthy

One of the paper’s authors, Professor Roger Hurst, says CurraNZ studies show New Zealand blackcurrant extract could be the ‘difference between winning a gold and silver medal at Olympic level’. 

Athletes such as 2019 Ironman World AG (18-24) champion Laura Addie, 2020 British 1500m Champion George Mills and 2019 World Multisport Champion Dougal Allan all use CurraNZ.


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, https://doi.org/10.1186/s12970-020-00354-9


CurraNZ is also guaranteed for muscle recovery and supports immune function.
