"After over 20 years of directing university lab research on polycystic kidney disease, I am thrilled that we have been able to translate the discoveries into transformative practical applications to benefit people affected by this disease.

Conservative dietary approaches are more powerful than any drug approach, and it’s a great equalizer.

Anyone can now do something about their PKD. I am proud of the talented and dedicated team at Santa Barbara Nutrients, who created KetoCitra, and the amazing dietitians at KNI, who have created the Ren.Nu program. Those are game-changers."

Welcome to Ren.Nu, a place of hope, healing, and transformation for those living with PKD.

Hi, I'm Kelly Welsh, program coordinator for Ren.Nu - and former Ren.Nu participant.

My journey with PKD started in my twenties and has been filled with challenges, including a significant decline in kidney function after contracting COVID twice. But it was the discovery of how nutrition could positively impact PKD that led me to the Ren.Nu program – a decision that changed my life.

As a dietitian with over 20 years of experience, I was accustomed to managing symptoms rather than preventing them. Joining Ren.Nu gave me hope and a sense of control, offering a strategy different from the textbook kidney diets. The program not only helped stabilize my kidney function as I awaited a transplant, but it also kept me free from the typical side effects associated with low GFR.

Now, as the Ren,Nu coordinator, I am passionate about helping others navigate this journey. Our program is not just a one-size-fits-all approach; it's a personalized plan that adapts to your individual needs, from dietary requirements to supplement advice. You'll have a dedicated dietitian guiding you, combined with the support of a community that understands your challenges. This program is about gaining confidence, learning sustainable practices, and experiencing the joy of feeling better in ways you never thought possible.

Join us and experience the transformation for yourself – because with Ren.Nu, you have nothing to lose and everything to gain. Let's embark on this journey together.

Now I have a new outlook on life, I feel empowered that the food I consume is going to help heal my body.
