    Review confirms the strength and scope of science of CurraNZ for promoting cardiometabolic health

    Scientist: 'We recommend daily intake because of the surprising scope of health benefits to people of all ages'

    A new peer-review paper1 investigating the health benefits of New Zealand blackcurrants, including the supplement, CurraNZ, reveals they provide clinically-significant improvements for metabolic and cardiovascular health, as well as more novel applications, such as reducing ‘old person’s smell’ by up to 80%.

    British researchers were surprised at the broad implications they have for health, recommending daily intake because of their proven benefits. 

    Fourteen of the studies were performed on CurraNZ, which is leading the way in health research into New Zealand blackcurrants internationally.

    New Zealand blackcurrants - and the varieties used in CurraNZ - are rich in naturally-occurring plant phytochemicals called anthocyanins, a sub-class of flavonoids.

    The concentrations, combinations and types of anthocyanins present in blackcurrants are not found in any other berry fruit.

    The studies showed short-duration intake of CurraNZ and New Zealand blackcurrants:

    • Increases fat burning in men and women during short and longer exercise durations
    • Boosts blood flow
    • Reduces hardening of the arteries
    • Reduces blood pressure in older adults
    • Improves insulin sensitivity and reduces post-meal sugar spikes
    • Reduces skin emissions, also known as ‘old person’s smell’

    Mark Willems, Professor of Exercise Physiology at the University of Chichester, Institute of Sport, Nursing and Allied Health, who led the review, says the research shows New Zealand blackcurrants have ‘broad implications for health’.  

    He notes: “We were taken back at the variety of applications we are seeing for New Zealand blackcurrants. It seems to work on a lot of things.

    “Given the evidence of its protective health benefits, we would recommend daily consumption of New Zealand blackcurrant as part of normal fruit and vegetable intake - and in population groups of all ages.”

    Blackcurrants grown in New Zealand and used in CurraNZ have one of the highest densities of anthocyanin of any berry fruit and 1.5 times more than blackcurrants grown elsewhere.

    The anthocyanins present in blackcurrants have anti-inflammatory and antioxidant properties, as well as helping improve blood flow and improving the health and function of blood vessels.
