Kidney & Bladder

Read what our customers have to say about our amazing 100% pure blueberry juice here!

Hi, I am currently doing dialysis and by doing some research I found this juice that was supposed to be great for the kidneys.

I began taking the blueberry juice and my blood tests were greatly improved including creatinine levels and urea. I stopped because I assumed covid had stopped all international shipping and I noticed that I began to feel tired and not so well. Numbers again creeped up and blood pressure was unstable. I ordered some more juice that will arrive by boat but I’m looking forward to feeling well again. The juice has got a lovely taste which is an added bonus considering how good it is for my health .

- Debbie, Australia - June 2020

Last year my kidney function dropped to 25% and since finding Mamaku Blue juice 6 months ago it has climbed to 40%. I am also a type 1 diabetic and have been for 42 years. I note that it doesn’t affect my blood sugar levels too much. 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.

Hi John and Anne 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. We will continue with this therapy and hope for a further improvement in the future. Thanks for your product and excellent customer services provided by John. *Results may vary.
Benaifer, Australia - February 2, 2018

My dad takes your blueberry drink 250 mls a day and the reason behind was his kidney function was going down, I believe your product is helping him in maintaining his kidney function at same levels and might also be helping in improving his GFR [Glomerular Filtration Rate]. I strongly recommend this product as if you’re in that situation you have to try and hope for the best. *Results may vary.
Ronnie A - July 19, 2017

In 2007 I underwent open heart surgery to replace my aortic valve.
Subsequent complications made it necessary to change medication to control atrial fibrillation, and extra fluid. Some medication causes kidney function problems. My sister-in-law also had the same surgery 12 years before me.

Sadly she passed due to kidney failure. Losing her pushed me to search online for help to preserve my kidneys. I came across Mamaku Blueberries. I have been using Mamaku Pure Blueberry Juice for a while now, 100mls when I first get up in the morning. It provides me with extra energy, and I am working full time. My regular 3 monthly testing for kidney function shows an improvement, my GP is very happy with the test results. Thank you Mamaku Blue, I am extremely happy with the results and recommend the product to anyone especially those with health concerns. *Results may vary.
Christine H - July 9, 2017

In October last year I had a bug which caused my kidneys to play up. I read about Mamaku Blueberry Juice and bought some to try because nothing the doctors could give me would help. The blueberry juice has been a great help to me and improved my kidneys right out of danger. It is very good for anything I believe health wise. Thank you. *Results may vary.
John S, Whakatane - July 4, 2017

Hello to you all I thought I should let you know how much the Blueberry Juice is helping me. I have been on dialysis for two years. This has meant sitting with the machine 5 hours 3x a week. Initially there were two parts to the treatment – cleansing the blood and removing excess fluid. Recently I realised I was able to drink 2 litres of fluid a day and with my kidneys working quite well I was not accumulating fluid. I now only need to have the cleansing of the blood which is a huge help. I am the only patient in the Wellington Renal Department in this situation! I have been drinking the Blueberry Juice everyday for 18 months. I’m sure this has helped the kidney function to improve. The nurses are amazed at my state of health. I’m not sure whether my renal doctor will agree that it is the Blueberry Juice. However I will discuss the results with him.
Thank you again. I’m very pleased that my son Derek L. suggested I take it and has been paying for it for me. This is a big help. *Results may vary.

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. I am pleased with the results of his kidney tests since taking the juice. So I can only say good things about the juice. *Results may vary.
Diane W - May 20, 2016

My husband, Prince, was told in late September, his kidneys were failing. Kidney function at that point was 16%, dialysis was just around the corner. Once we were over the initial shock of that, I got on the internet to find out as much as I could, and found Mamaku Blue. We drove there as soon as we could, and bought a dozen bottles. In early October he began taking 150mls daily, as well as the health powder, in his cereal. His energy levels picked up straight away, he could mow the lawns without tiring as well as other jobs around the house. My husband is 68 and still works a 50hr week. Our next 2 visits to the renal clinic, were disappointing as kidney function was now down to 13%. Deterioration was quite rapid but we carried on with his daily doses, feeling positive that we had to give the juice at least 6 months to start working. We had to go through the dialysis options with a team of people because it seemed to be the next step a scary time for us both. Next renal visit, function was up a % to 14%. We were blown away by the results, and went out to celebrate this huge achievement. It meant dialysis wasn’t looming anymore and we were so happy. We had another renal visit just 2 weeks ago and he’s still at 14%. That’s alright because we had a bout of food poisoning which wasn’t pleasant, but we think if that hadn’t happened his function would probably have been up. The fact that it hadn’t got worse is still a positive for us. Our faith in the blueberry juice only grows, it’s wonderful stuff and we wouldn’t be without it. We’ve been told by certain people that you can’t repair shot kidneys. I believe my husband’s kidney’s are getting better, because of the juice. If we can get his function to 16% he won’t need a donor kidney or dialysis, that seems entirely possible.*Results may vary.

I am absolutely impressed by the endless miracles of this wonderful blueberry juice. It helped to normalize my mums diabetes and improve the kidney function. For me its a must for my ongoing weightloss regime. Thanks for the wonderful product. *Results may vary.
Sanjay S - November 21, 2015

I started on Mamaku Blue juice earlier in the year after doing some researches and it shows that Blue berry juice is great for people with type 2 diabetes with kidney issues. Since taking the juice my urinal tests has dropped from 37 to 32 and improving. The aim is to go below 30 which is the norm. I take a glass a day on an empty stomach and this seems to work just fine. I would continue to order the Juice from Mamaku Blue and would recommend it to anyone. Many thanks and I look forward to dealing with you all at Mamaku blue. You have a great team there. *Results may vary.
Morconi S, Auckland - November 20, 2015

I am the lucky recipient of a kidney transplant-for which I am so very grateful. About a year after the transplant my kidney was attacked by BK virus. The specialists tried several procedures to reduce the number count of the virus in my system and during that time a friend told me about Mamaku blueberry juice. I have been taking it every day since then and gradually the viral count reduced. I will always take the blueberry juice as I feel it contributed to reducing the virus in my system. *Results may vary.

I just wanted to write and let you know that my father had a Chronic Kidney disease and he was losing his kidney function. I googled to find what’s out there to help him improve his kidney function. I saw Mamaku Blue. I ordered few bottles for him to try and saw good result so started ordering dozen every time as my fathers kidney has stabilized. I would highly recommend this to people who are suffering from kidney disease. *Results may vary.
Nadeem M - November 19, 2015

My brother has got chronic kidney failure since last year which make him very weak. He feels much better after taking 6 bottles of blueberry juice he can feel the difference and he’s getting better and more healthy. My husband and I also love Mamaku blueberry juice. We feel great after taking Mamaku blueberry juice. *Results may vary.
Ruli - November 3, 2015

We are from Samoa and my husband was advised that most probably he will have dialysis early this year. This was last year. He began searching in the Internet for help and he found Mamaku Blueberry Juice. After taking Mamaku Blueberry Juice for 6 months plus having a diabetic diet his glucose level is now normal and he is not taking anymore Metformin tablet which he used to take a daily dose and also the specialist has also told him that his kidneys have no clots and they are stabilized. We highly recommend Mamaku Blueberry Juice to everyone who has diabetic and kidney problems. We would like everyone with this problem to know that there is a solution. *Results may vary.
Talosaga A, Samoa - October 31, 2015

My Aunt was diagnosed with stage 4 chronic kidney disease and was on dialysis 3 times a week. However after trying blueberry juice she only needed dialysis once a month. We also noticed that she had lots of energy, she was full of life and generally improved her overall health since she started taking the 100% blueberry juice. Due to financial reasons we could not afford to keep up with the blueberry juice as she was paying for dialysis. As she stopped having the juice we notice that her health deteriorated, she had no energy and got sick regularly. Therefore, we are going back to the 100% blueberry juice. I strongly recommend this product to others. One needs to try it to believe it. *Results may vary.
 Arishma L - September 20, 2015

I have been using Mamaku blueberry juice for a year now and my kidney function has improved and my diabetes much easier to control I feel a whole lot better and I wouldn’t be without my Mamaku. I believe my eyesight has stopped deteriating and my brain is sharp. I am 69 years old and still work fulltime thanks to Mamaku. *Results may vary.
Bill D - September 20, 2015

I also have poor kidney function due to a disease called Glomerulonephritis. I have now had this disease since 2011. I started taking Blueberry juice after reading the reviews on your website. I was in remission for approx. 1 year while taking the juice. – then stopped and the disease flared up again. Maybe it is coincidental but I have now been in remission since March last year, and I am still taking the Blueberry juice. As you can see there is no way I would stop taking your juice as it certainly has worked wonders for me. I thank you too, for your amazing product. *Results may vary.                                              
Anne S, Te Puke - August 23, 2015

My mother has type 2 diabetes, which has brought about very poor kidney function as well as other health issues, so last year we did some research and read good things about your Mamaku blueberry juice and decided to get some for her to try and mum has not looked back since. It has helped her kidney function stabilize, given her more energy and generally helped her overall health since she has started taking it. Thank you for such a great product Nicola. *Results may vary.                                             
Nicola W, New Zealand - July 31, 2015

18 month ago I was in Auckland Hospital with kidney failure – when discharged I was on Recormon injection 4000IU once a week. About 12 month ago I started Blueberry Juice 150 mls daily. Since I started Blueberry Juice the Renal doctor has stopped my injections completely. My kidney test at my doctors has continued to improve to a reading of 48. The only thing I have done is take Blueberry Juice every day. Thank you. *Results may vary.
Barry Y, Auckland - July 18, 2015

OUR CUSTOMER WHO HAS GONE OFF DIALYSIS BY TAKING MAMAKU BLUE PURE, 100% BLUEBERRY JUICE. It was in early July 2014 that my wife was admitted to hospital with kidney failure. At 85 years of age she was already a diabetic on 32 units of injected insulin daily and had had a pacemaker inserted in 2013 and also had severe osteoarthritis affecting the whole of her spinal column. She was also legally blind and wore a hearing aid in both ears. For 3 days after her admission she was in a coma and was given a slow dialysis after which she slowly regained consciousness. Her urine output early was nil or next to nothing and this was so for many weeks. The official medical outlook was most pessimistic but she was maintained on 3 dialysis sessions per week. I learned from the internet about favourable responses attributed to the use of blueberry juice in renal failure, especially on your site at Mamaku Blue.

After consulting with her dietitian and her physician, I started her on
Mamaku Blue in September. The first thing that I soon noticed was a mild but quite distinct improvement in her urine output and that in itself was encouraging. Finally, she was allowed home with strict attention to diet in late November but still on 3 dialyses per week. Unfortunately, she had been home for only 3 weeks when she suffered an embolic stroke on Christmas Day 2014 and was admitted back into hospital. She still has a left-sided paresis (arm and leg) and is now bed-ridden but she communicates well and is a pure delight. Her facial palsy is almost undetectable. It was not until early February 2015 that she was again allowed home from hospital as we had arranged for home nursing and home dialysis. Since September 2014 and throughout all this, I had been able to maintain her intake of 150 mls of Mamaku blueberry juice daily. She has recently amazed us all when her renal function began to show definite signs of improvement and the renal physician began to reduce her dialysis from 3 sessions to 2 sessions per week. Then, to our final amazement he announced that she had improved to such an extent that she could come off dialysis altogether. She has been without dialysis now since early March 2015 (the past 9 weeks) and, what’s more, she no longer requires her daily dose of insulin! Her back pain has improved to the extent that she no longer takes any regular analgaesics for it. All her other physical signs and observations are within the normal range.

Her last blood test about 10 days ago showed a still further improvement in renal function and she seems to be going well. As well as wonderful medical attention and nursing care there have no doubt been many prayers offered for her recovery during this period and we are thankful indeed for them all.

Nonetheless, there is no doubt in our mind that Blueberry juice has been the main vehicle by which her amazing improvement has been achieved and we are most grateful for that and also to Anne Frost at Mamaku Blue for her early encouragement ’to try it out.

This seems a long testimonial but it is worth telling despite our age and maybe more so because of the age! Anyway, we would be happy for you to use the above.

Best wishes and thank you again. *Results may vary.
Geoffrey S, Australia - May 1, 2015

I purchased the Mamaku Blueberry Juice when I was desperate for something to help my 89 year old father, with his failing kidney function.

At that stage he had 20% function and was failing fast. Doctors really didn’t have any answers, except to say that he would soon need to consider dialysis. After 3 weeks of taking the juice, his kidney function improved to 29%. Doctors couldn’t believe it as they had told him the best they expected was that he may hold at 20% if he was lucky. Three weeks later, there was further improvement to 38% and after another month it has improved further to 44%. There have been no other changes to his medication and this we believe is all due to the Blueberry Juice, of which he takes 150ml per day.          
My mother of 85 years, has Type 2 diabetes and suffers repeated urinary tract infections. She struggled to keep her blood sugar reading stable. Readings would range from 7 to 10 and sometimes higher. She has also decided to take the juice and has had fabulous blood sugar readings of 5 and 6 since being on the juice. They are both very happy and extremely relieved. I have no doubt it is helping in other areas as well. This will be a standard order for them now. There are just too many benefits to even consider not taking the Mamaku Blueberry Juice. It’s hard to believe that something that tastes so good, can actually be good for you ! Thank you so very much for this wonderful product. You have no idea how much pain and anxiety has disappeared from our lives since we found your company and ordered this amazing product. *Results may vary.
Julie, Australia - October 10, 2014

Second time I have purchased the 1 litre pure 100% blueberry juice on line. I have found it helped get my kidneys back in shape as blueberries are low potassium food and anti-oxidant rich food that doesn’t harm your kidneys. So even if it is a bit expensive fruit it does work. I had renal failure and was told next step was dialysis which wasn’t where I wanted to go. Started drinking 100 mls of pure blueberry juice with hot water like a tea each morning. Went to my doctor after a month and my kidneys were good, blood pressure was good and lost weight too. Doctor said all was good with me and keep up whatever it I was doing. Drinking blueberries was the change in my life. Blue berries and lots of water. Thank you. *Results may vary.                                              
Sharon S, Auckland - July 11, 2014

My husband Terry was told he had chronic kidney failure, wow, how? He had very high cholesterol so the Dr put him on a high dose of statin drugs which did nothing so they kept putting up the dose. We have read since that the statin drugs can affect your kidneys. The only thing they (Dr) could give him was blood pressure pills. After blood tests which read his kidney function at only 38-39% and the fact that they were leaking protein at a number of 12.4 (normal is 2) I started to look on the internet and found Mamaku blueberries which they said were very high in antioxidants would help. We visited the shop and ordered 6 bottles to start with and with him taking 150mls daily his next test the protein leaking went down to 4.2. The Dr was amazed and said keep doing what your doing. He did cut the juice down to 100mls but it went back up to 10.4 again. He is back taking 150mls and we have been testing him every month or so to check it and at the moment is has gone down to 4.4. The kidney function has stayed at the same %. So we continue to monitor his kidneys. This product is very good and has so many benefits we were very pleased to have come across it and told a lot of friends and family about it. *Results may vary.

Thank goodness for Mamaku Blue’s Blueberry Juice!

Some years ago I called into Mamaku Winery on a trip to Rotorua and along with an assortment of delicious goodies, took home two bottles of Blueberry Juice. The velvet texture and rich smoothness was delicious and I indulged myself with the special treat half a wine glass of juice each morning with breakfast.

This year I discovered Mamaku Blueberry Juice was available online, directly from Mamaku Blue, and delivered to my door. As I work full time this has meant that for the last ten months I have been able to keep up my daily routine of a Blueberry Juice with breakfast.

WOW! I have noticed a HUGE difference in my overall health and sense of wellbeing. My energy level has improved and niggling kidney pains from surgery some years earlier, have disappeared. I have a family history of Macular Degeneration, and I am very pleased to read that blueberry juice has nutritional properties, which assist in slowing down Macular Degeneration. Thanks to Mamaku Blue Blueberry Juice I feel more optimistic about my quality of health and wellbeing in the future.

Over the past 7 years I have had 3 pneumonias. I now have Bronchiectasis in my lungs along with a bug called pseudononas aeruginosa. I have been on many antibiotics over these years, and in 2012 I found out my kidneys were only working at 69%. I did some research and found that taking Blueberries can help Kidneys. I got into Mamaku Blue in Rotorua, read other peoples testimonials and their success and decided to give it a go, 150 mls every day. Had my next Renal check 12 months later mid September 2013. The result was an improvment by 12% my kidneys now function at 81%. I´m absolutely delighted and will be staying on the Blueberry Juice. Thank you Mamaku Blue. *Results may vary.
Pam - October 11, 2013

I am a diabetic with type 2 diabetes on insulin which gave complications to my kidney. I was seen by the doctor on a monthly basis to monitor the function of my kidney, but on my fifth visit to the doctor I was told that my next appointment will be in a year’s time. I believe the Mamaku Blueberry Juice made a difference.

I use to have trouble with my eyesight giving me blurred vision when my sugar level reading rises in the 10 to 15 range. The Blueberry Juice has made a difference – today my eyesight is clear.

The Mamaku Blueberry Juice is a blessing – Thanks to Anne and the team at Mamaku Blue. *Results may vary.
Eturangi - September 9, 2013

I am a diabetic with type 2 diabetes, this led to my kidney failure. I lost at least 75% of my kidney function, and was on Hemodialysis at the hospital for up to 6 hours every day.

I was introduced to Mamaku Blue Pure – 100% Blueberry Juice in January this year 2013. I took the suggested amount for kidney failure of 150mls per day. This had an immediate effect of increasing my urine output from just a quarter of a litre a day to filing the litre bottle and this has continued until the present day. I believe this Mamaku Blue Juice seems to have kicked my kidneys into life again. I am now on APD Dialysis at home, plugged in at night while I sleep – I have my life back, I can now do other activities in the day time.

I had trouble with my eyes my vision was blurred, but after drinking this Mamaku Blue Blueberry Juice my vision became clear – however when I ran out of Juice my vision became blurry again once back on the Juice my vision cleared. Amazing result.

The Mamaku Blue Pure 100% Blueberry Juice still has it’s natural sugars but did not seem to have a negative affect on my blood sugar levels which remain to be quite good. I believe it has also helped my pancreas which is now functioning better.

My energy levels have really increased since having the Mamaku Blue Juice, declines when I run out, and comes back when I start the Juice again.

On the medical side my doctor is very pleased with my medical results and has informed me that my blood count is becoming normal, so I do not have to take the blood count pills anymore, he has also taken me off the pills that stopped the potassium and calcium build up in my body as the levels of both are now normal.

I believe the Mamaku Blue Juice takes the toxins and excess fluid out of your body. I am so pleased I found it – but wish I had been introduced to this Mamaku Blue Pure 100% Blueberry Juice before my kidneys had got so bad. *Results may vary.
Graham - August 3, 2013

In December 2012 I was stage 4 kidney failure and I was no longer able to process food high in potassium. I had 3 visits from the pre-dialysis nurse and stent surgery to enable me to have home dialysis was imminent. We discovered Mamaku blueberry juice advertised on line and decided to try it, we immediately ordered 12 bottles. After a month the first visit with the renal nurse practitioner showed the blood test results to have improved and to date they have been continuing to do so. All thoughts of dialysis have flown out the window and we now only have blood tests 2 monthly. *Results may vary.

I am so thrilled with the results of taking your Mamaku Blueberry juice. I was diagnosed with Renal failure November 2012. I was Category 4 and in line for Dialysis. My count in late December 2012 was down to 2,5%! This proves from my perspective that Blueberry Juice definitely works! I would recommend it to any one with Kidney Failure. I have now started on my 2nd order of one dozen bottles which are couriered to me very promptly. My thanks to all who pick, sort, crush, bottle and sell the Mamaku Blueberry Juice! *Results may vary.
Marlene, Manukau City - April 24, 2013

I visited Mamaku Blue last March and I was very interested to read Colleen MacCarthy’s testimonial as I also have chronic kidney failure. I was at stage 4 – advanced kidney failure with severe decrease in the filtration of my kidneys. Stage 5 is Dialysis to survive. Anne saw me reading the testimonial and told me a little of Colleen’s success and suggested I have a try. I tasted the sample of juice, and it was so delicious! I bought a bottle and went on the recommended dose of 150 mls daily. A week later I went off for my fortnightly blood test and I could hardly believe the result, my kidneys had improved by 12% and I was in Stage 3 – chronic kidney failure with a moderate loss of filtration! What a difference it was. I have been continuing to order my fortnightly supplyand my kidneys have remained in Stage 3. It is now the last day of May and I know it is the blueberry juice that has caused this amazing result. I will be keeping on with my daily dose for sure. Many thanks to you too Anne for your kindness.

Feb 2012 diagnosed with kidney failure.
(Globular Filtration Rate) GFR was 27 when I came to Mamaku Blue Blueberry Experience Complex.
Two weeks of 150mls of Mamaku Blue 100% Blueberry Juice a day, GFR rate rose to 36
GFR rate remained around 35 34
Reduced the amount of Blueberry Juice per day and ran out before my test..
Next test showed the GFR rate back down to 25.
Back to 150mls per day next test GFR rate up to 37.

I was introduced to the Mamaku Blueberry juice in December 2009. I have chronic kidney failure, and chronic heart disease. At that time my Nephrologist had told me that my kidney function was so bad that I would have to go on dialysis. I refused to do that and told him that he needed to find an alternative. I visited my relatives in New Zealand that Christmas, visited the farm and was introduced to the juice. I have been taking the juice on a daily basis ever since, about 150ml per day. Just a couple of weeks ago, I was told that my kidney function was at 100% and that my heart was the best it has been in 12 years. The doctors said that whatever I am doing, keep doing it. I thoroughly endorse the juice, I think it is a definite winner. *Results may vary.
