Doctor Says Potent Berry Supplement is a ‘Perfect Solution’ to Fill Common Nutrient Gap

A natural berry supplement that turns back the heart health clock, aids metabolism and boosts the health benefits of exercise has arrived in the US.

New data1,2,3,4,5 is showing that as a nation, we should be upping our dietary intake of dark berry polyphenolic compounds, called anthocyanins, which offer significant, clinically-proven health and lifespan benefits.

Over 40 published studies have showcased the impressive benefits of the anthocyanin-rich supplement, CurraNZ – from turning back the clock ten years for heart health in older adults33-38, improving blood sugar management32 – to muscle recovery10-13, exercise performance14-23 and energy metabolism24-31.

Two recently-published peer-reviewed papers8,9 evaluating the health and active nutrition data on the phytochemicals in CurraNZ, a supplement made from anthocyanin-rich New Zealand superfruits – blackcurrants – have revealed their multiplicity of health effects.

Dr Kenna Stephenson, MD

Dr Kenna Stephenson, MD, Clinical Professor at the University of Arizona College of Medicine and an advisor to CurraNZ – www.curranz.com – describes CurraNZ as a ‘perfect solution’ for Americans looking to source a high-quality, trusted source of anthocyanins to incorporate in their diet.

Dr Kenna Stephenson confidently prescribes CurraNZ to her patients and takes it as part of her own health regimen. She says: “Many of my patients are challenged in finding access to fresh berries as part of a healthy diet, and CurraNZ is a perfect solution. This dietary supplement boosts anthocyanins which help the body in stress recovery and has favorable effects on the cardiovascular system and overall metabolism.”

“CurraNZ has proven potency and is supported by multiple evidence-based research studies. I confidently prescribe this supplement to my patients seeking their greatest potential in aging well and enhancing benefits from physical activity”.

New Zealand blackcurrant anthocyanins are scientifically recognised for their powerful antioxidant, anti-inflammatory and blood flow-promoting properties, which are central to good health.

Fewer than 0.1% of Americans have eaten a blackcurrant, but CurraNZ offers a year-round, high-quality supplemental source to fill this concerning, yet common, nutrient gap.

Researcher Mark Willems, Professor of Exercise Physiology from the University of Chichester in England, has authored 40 of the peer-reviewed New Zealand blackcurrant studies that have shone the light on CurraNZ. Professor Willems believes that individuals looking to live a healthier, more active life, should be incorporating dark berry anthocyanins into their diets as an essential ‘daily staple’, because of their array of positive effects.

One capsule of CurraNZ contains 105mg anthocyanin, equivalent to a large handful of New Zealand blackcurrants. Scientific literature demonstrates wide-ranging health and lifestyle benefits for consuming doses in the range of 105mg-315mg anthocyanin (1-3 capsules of CurraNZ).

Professor Willems says: “The normal dietary intake in the US is just 12.5mg of anthocyanin. People are deficient in anthocyanin and not aware of it.

“While there are no guidelines for anthocyanin intake, the evidence is building that we need to eat more fruit, especially berries and vegetables rich in anthocyanin compounds, or incorporate high-value functional foods, through fortification or taking anthocyanin supplements.”

In summary, Dr Stephenson, says: “Every cell is a microcosm, and its functions and intelligence are dynamic. Nurturing our cells with plants through diet and supplements is vital to our well-being, and it is exciting to have this source of New Zealand blackcurrants so richly endowed with anthocyanins available to patients in the USA.

“My preference in caring for patients is to implement diet and lifestyle changes to enhance health, as opposed to prescription drugs and procedures. CurraNZ can support them in their health and activity goals as a natural, food-based adjunct.”

CurraNZ is available from www.curranz.com and Amazon USA, 30 x 300mg (105mg anthocyanin) capsules cost $34.95.

FACT: Anthocyanin consumption rates in the US are amongst the lowest in the Western World, where average reported intake is just 12.5mg/day6, compared to 40-60mg in Europe7
