Greycoat Research Expert Guidance for CKD Cats
With over 1,000 consultation cases worldwide, Greycoat Research provides expert-backed guidance for CKD cats, helping them maintain kidney health and manage the progression of CKD through data-driven care.

Dr. Toru Miyazaki was the first to uncover the mechanism behind cat CKD.
Dr. Toru Miyazaki, the world's leading authority on AIM research, provides Greycoat Research with expert guidance in developing AIM-based supplementation to support kidney function. His research has contributed to innovative treatments that help manage CKD in cats.
Eli, a 4-year-old Abyssinian, was diagnosed with early-stage kidney disease after routine bloodwork revealed elevated creatinine and SDMA levels. After beginning Dr. Toru Protocol supplementation, Eli’s kidney values gradually improved, reaching levels lower than when she was a kitten.

Testimonial from Ellie's Owner
"I was amazed at how all of Ellie's kidney levels improved across the board, especially her creatinine, which dropped to lower than when she was a kitten. Even our vet was surprised by the results. I’m so grateful for these supplements and the support from Greycoat Research. Now, I’m looking forward to Dr. Toru Miyazaki’s AIM injection cure becoming available so we can ensure long-term kidney health for Ellie."

Greycoat Research has provided consultations for over 1,000 cats, with 97% of stage 2 and 3 cats showing improved kidney health after following our tailored management plans. If your cat has been diagnosed with CKD or has high creatinine levels, taking action now can lead to lasting improvements.
