We just received this lovely testimonial from Naomi in Scotland. Thank you Naomi and we are very happy for you!

"I'm 53 years old, I have PKD (low function - eGFR 22) and since starting on a ketogenic therapy journey in June 2025, the quality of my life has improved drastically. This is in part due to drinking KetoCitra every day and following a PKD-friendly keto diet as well as sticking to intermittent fasting at least 5 days a week. I've been able to reduce my blood pressure medication by a third, halve my asthma medication (1st time in 40 years!) and I've dropped 2 dress sizes - within a 4 month window! I am excited to see the actual impact on my kidney function at my next renal appointment. This is life changing for me - even if my kidney function doesn't go up (which I hope it will!), I feel I can actually change the trajectory of this condition and possibly live a whole lot longer with my own kidneys. I am very grateful to the researchers who have committed their careers to looking at the root cause of PKD and to those who have developed a supplement that massively improves the well-being of PKD patients."
