Gold-standard science and impeccable credentials you can trust

    on May 17, 2021

    THE sports nutrition market is notorious for overhyped, unproven products that don’t live up to their claims.

    In CurraNZ however, you can rest assured that gold-standard science, efficacy and consumer trust are central to the product’s impeccable pedigree.

    To date, over a decade of clinical research has been invested in CurraNZ and New Zealand blackcurrants, resulting in 30+ sports performance and recovery studies.

    Last year, an independent published review of the scientific data revealed CurraNZ to be one of the most effective legal performance-enhancers in sports nutrition1.

    The muscle recovery properties2,3 of our blackcurrants were discovered in a decade of New Zealand research – and they have a self-substantiated health claim there to prove it.

    Most people don’t know that blackcurrants are nutrient powerhouses. A new breakthrough in sports nutrition, they are now being deployed as a secret weapon in some of the world’s top sporting teams for a recovery edge. 

    But don’t be intimidated by their ‘eliteness’ – they’re great for active people of any persuasion.

    We know CurraNZ works. That’s why every carton comes with a 100% money-back guarantee for muscle recovery.
