Supports Cell Survive to Protect Kidney Function
In Cats with Kidney Disease, Each Cell Could Be at Risk
If you’ve already supported your cat’s waste clearance with AIM, the next step is protecting the kidney cells themselves.
As kidney disease progresses, feline kidney cells become increasingly vulnerable to oxidative stress and inflammation, making them more likely to die off.
Damaged kidney tissue rarely recovers; as such, even a small loss in cells can lead to permanent loss of kidney function.
AMPK: The Key to Kidney Cell Survival

Dr. Kobayashi Motoo, the First Veterinarian to Apply AIM Research to Cats
When it came to feline kidney care, Dr. Kobayashi emphasized more than just kidney waste clearance.
He highlighted the importance of regulating energy metabolism inside the cell—specifically, activating AMPK.
AMPK is a physiological metabolic pathway involved in cellular energy production and repair.
It has gained academic attention for its relevance to feline kidney health.
Greycoat Research developed Intensive Protocol to reflect this insight—a multi-ingredient formula designed to support
cellular survival from the inside out.

Our Vitamin Philosophy for Cats with Kidney Disease
Intensive Protocol was formulated with the metabolic challenges of kidney disease in mind.
Rather than adding every possible nutrient, we chose only what matters, and removed fat-soluble vitamins that could build up in the body.
- No Vitamin A or E
→ These fat-soluble vitamins are difficult to excrete and may accumulate in cats with reduced kidney function - Minimal Dose of Vitamin D3 Included
→ Vitamin D3 is paired with Vitamin K2 to help stabilize calcium metabolism, especially when D3 can’t be effectively activated by the kidneys - Comprehensive B Vitamin Support
→ Cats with kidney disease often lose B vitamins more easily, so we included all 8 essential B vitamins, from B1 to B12 - Vitamin C for Antioxidant Support
→ Vitamin C was added to protect cells under oxidative stress
✔ Designed to avoid buildup of fat fat-soluble
✔ Focused on what supports energy, stability, and cellular survival

My cat is already taking other supplements. Can I still give Intensive Protocol to my cat?
Yes, Intensive Protocol is compatible with most supplements. Intensive Protocol contains 20 active ingredients that provide antioxidant and immunity boosting properties. However, no matter how good something may be for your cat’s health, too much of it can end up doing more harm than good. As such, if your cat is already taking many other supplements, we recommend reaching out to use for a free consultation.

Can I give my cat Intensive Protocol and Dr. Toru Protocol at the same time?
