keto acid supplementation?

[HisLittleOne]

Does anyone use keto acid supplementation along with a low protein diet to help preserve kidney function and prevent further decline in eGFR?

I have read anecdotal reports from people who were able to stabilize and even increase their eGFR and other kidney function values by using this protocol. I am trying to keep my kidney function from decreasing (currently eGFR 57 with creatine high normal .96) so I’m considering this.
