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.

Byeol, a 2-year-old cat, had no history of kidney disease but was monitored due to concerns about kidney health. She was introduced to AIM-based supplementation to support her renal function. Over the course of a month, her creatinine levels showed slight improvement, and her kidney values remained stable.

How Did Byeol Improve?

Energy & Activity

  • Increased energy levels, with more willingness to play.
  • Showed more interest in toys than before.

Weight & Appetite

  • Weight increased slightly; owner was advised to maintain current weight.
  • Noticeable increase in appetite.

Appearance & Other Changes

  • Started vocalizing more and engaging in social interactions.

Supplement Adjustments

  • Started with Dr. Toru Protocol, Intensive Protocol, probiotics, and omega-3 supplements.
  • Continued monitoring with no adjustments needed at this stage.

Byeol’s kidney values remained within a healthy range, with a slight decrease in creatinine and phosphorus levels observed within just 1 month of supplementation. Additionally, her appetite and energy levels improved, and she showed more interest in play. While her weight slightly increased, maintaining a healthy balance is essential, as excessive weight gain can also be a concern in feline health management. Given that weight loss is a common concern among CKD cats, the fact that Byeol has been able to avoid losing weight is still a promising sign.
