Nutrition for pkd care

Science-backed renal nutrition tailored for Polycystic Kidney Disease (PKD).

Managing Polycystic Kidney Disease (PKD) requires a structured renal diet and targeted nutrition. A low-carbohydrate, ketogenic diet helps by reducing renal stressors such as oxalates and phosphates. Combining this approach with the medical food KetoCitra® can make kidneys more resilient by reducing inflammation and protecting kidney function. The Ren.Nu program addresses two key mechanisms: metabolic imbalances and damaging renal microcrystals. The goal is to slow disease progression, giving those affected by PKD proactive options to manage symptoms and improve long-term kidney health.

How to get started with the Ren-NuTM program for ADPKD

Watch this brief video in which Dr. Melina Messing and Dr. Thomas Weimbs discuss how to get started with the Ren-Nu Program.

 

THE RESEARCH

BASED ON RESEARCH FROM LEADING EXPERTS

“Our research discoveries on the effects of ketosis and renal micro crystals has identified two mechanisms that control disease progression in polycystic kidney disease. Both mechanisms can be addressed by nutrition and lifestyle changes. This has led to the creation of KetoCitra and the Ren.Nu program to help patients take control of their health. For the first time, the paradigm is shifting and we cannot simply regard ADPKD as a purely gene-driven disease with an inevitable outcome anymore. Now, there is something patients can do about it!”

THIS IS WHAT OUR PATIENTS ARE SAYING

Michelle

“I went through the 23 Ren-Nu Summer program. In early Aug my GFR was 39, Sept 29 I was registering 1.5 ketones and my GFR was 54.

I have a cheat day once a week now that I’m fat adaptive, but don’t go overboard on carbs. I have been taking Ketocitra since June 23, every day twice a day.”

Tera

“I was part of Ren-Nu last spring and have had great success. In 6 months my GFR went from 32 to 45, and my Creatinine went from 1.95 to 1.45. In addition to that I feel great! I do intermittent fasting 16/8 most days, take KetoCitra daily and am very pleased with the results so far.”

Carol

“I went through Ren-Nu last spring-Summer, and by August, my eGfr had improved from 31 to 43. I’ve continued, although a little more casually, and my November labs showed a stability and maybe even a little more improvement. In addition, my bp improved, allowing me to drop one med and cut the other in half.”

Christine

“I am so grateful for all the research, education and support from Santa Barbara Nutrients and Ren-Nu. You all make it so worthwhile. My life has really changed. I knew months ago, I knew that it was working as I could feel the difference when I felt the cysts going down on my right kidney.

Jason

“I’ve been on the Ren-Nu diet plus KetoCitra for 15 months and my eGFR has improved. I’m grateful for the amazing work that you are doing for the PKD community
