How can blueberry juice help my kidneys?


High in Anthocyanins

Anthocyanins possess antidiabetic, anti-inflammatory, antimicrobial, and anti-obesity effects. And they're blue :)

#1 for Antioxidants

Antioxidants may protect your cells against free radicals, which may play a role in flaring up chronic diseases.

Low in potassium

Blueberry Juice is low in potassium, phosphorus and sodium which all put a strain on the kidneys.  Our juice has all the good stuff and none of the bad.

A great natural product that restored my health after acute renal failure.

The results were measurable and defied conventional medical opinion. Seven years on I continue to take it for its all-round benefits. A product of real benefit and no side effect risks. *Results may vary

Last year my kidney function dropped to 25% and since finding Mamaku Blue juice 6 months ago it has climbed to 40%. 

I intend to continue taking this Mamaku juice for its many positive health benefits as well as the positive result to my kidney function. *Results may vary.

 I am so pleased to inform you that my husband's kidney function has improved.

Since he has started taking the Mamaku blue blueberry juice daily from September last year, his creatinine count has gone down from 125 to 115 and his Egfr has improved from 58 to 61. He is currently on no other medications. *Results May Vary

I am pleased with the results of my husband's kidney tests since taking the juice.

My husband was nearly at the dialysis stage when I went into Ask Jeeves and queried kidney failure. One of the testimonials for Mamaku Blue Berry Juice said that it was helpful.  So I can only say good things about the juice. *Results may vary


From JUST $2.20 a day in a 750ml bottle.

That's less than half the price of a good Flat White.
