How AIM Supports Kidney Care

AIM is a protein related to the body’s natural waste-cleanup process.
Dr. Toru Miyazaki’s research helped explain why AIM may play an important role in feline kidney care.

Why These Ingredients Matter

  • Amino Acid Complex

    A core nutritional foundation for AIM-based kidney support

  • Coenzyme Q10

    Supports cellular energy and daily vitality

  • Resveratrol

    A polyphenol that supports healthy aging and antioxidant balance

Because Kidney Care Matters So Much

Kidney problems affect not only cats, but also the families who love them.
Greycoat Dr. Toru was designed in collaboration with Dr. Toru Miyazaki, M.D., Ph.D., to bring AIM research into daily kidney care.

Carefully Reviewed for Daily Use

  • Used by 15,000+ cats across Korea and Japan.
  • Developed with input from veterinarians, pharmacists, and nutrition specialists.
