KDIGO and KDOQI recommend a very low protein diet with keto acid analogs. Albutrix is that medical food, not a supplement. In many countries it is the only one patients can actually buy. The Stopping Kidney Disease books have more than 5,000 Amazon reviews across the series. Money-back if you are not satisfied. As far as we know, the price is lower than other keto acid analog options patients can get.
The Book is the Study
Albutrix is protein formulated for kidney patients. It is a medical food, not a supplement. It gives you what protein gives you, with less waste for the kidneys to clear. Microtrix is included free.
If you already used the program and only have old labs to send, that is a separate, older ask. Follow the instructions on the Participate In Our Research Study page.
