Hello, I’m Alex Shin, a pharmacist at Greycoat Research.

When you care for a cat with chronic kidney disease (CKD), you may wonder what other owners are doing.

Today, I’m sharing two stories from Korea. We’ll also look at the research behind our approach to daily kidney nutrition.

Over 300 Intensive Reviews from Korea

Cat owners in Korea have shared more than 300 reviews of Intensive. Here are two reviews of kidney care sets containing Dr. Toru and Intensive.

A Consistent Care Routine

“I give these regularly to my cat with kidney problems. We’re in the third year now, and the test results are still stable.”

Daily Care for a 15-Year-Old Cat

“Since starting both products, my 15-year-old cat has gained a little weight. My cat also seems to have more energy, so I keep giving them.”

Why We Focus on Low-Grade Inflammation

Routine kidney blood tests are important. But they do not directly measure inflammation inside kidney tissue.

We are interested in low-grade inflammation—inflammation that continues at a low level over time. Persistent inflammation can contribute to kidney tissue damage.

This is one reason our research considers both kidney function and the processes taking place inside the kidneys.

Why Consider Intensive Alongside Dr. Toru?

Our interest in low-grade inflammation shapes two connected approaches.

Dr. Toru — An AIM-Based Approach

For Dr. Toru, our starting point is AIM research.

p>AIM is a protein studied for its role in clearing damaged cell debris from the kidneys. In mice with acute kidney injury, a lack of AIM impaired debris clearance and prolonged inflammation.

This research helps guide Dr. Toru’s approach to daily kidney nutrition.

Intensive — A Closer Look Inside Kidney Cells

With Intensive, we look deeper at the cellular processes linked to low-grade inflammation.

We pay particular attention to mitochondria, which help cells produce energy. Experimental kidney research has also linked mitochondrial damage to inflammation.

Intensive is designed to complement Dr. Toru, with a focus on cellular energy and mitochondrial health.

Dr. Toru brings an AIM-based focus. Intensive adds a closer focus on kidney cells and their energy needs.

Why We Study These Ingredients

Resveratrol and curcumin are two of the ingredients in Intensive. Our interest in inflammation and cellular health helps guide these choices.

Resveratrol — Our Research in Cats

Our team studied resveratrol in cats and published the findings in 2025.

In a small group of overweight and obese cats, an inflammation-related blood marker decreased after four weeks of supplementation. This was an ingredient study, not a CKD treatment trial.

Curcumin — New Findings in Cats with CKD

A study published in July 2026 followed 16 cats with stage 3 CKD for 60 days.

The cats were randomly assigned to two groups. Eight received standard veterinary care. Eight received standard care plus curcumin.

Compared with standard care alone, the curcumin group showed:

A lower inflammation-related marker
NF-κB was lower on days 30 and 60.

Lower SDMA
This blood marker of kidney function was significantly lower on days 30, 45, and 60. SDMA was the study’s main outcome.

A lower urine protein ratio
UPC, a measure used to assess protein loss in urine, decreased over time. It was also lower than in the standard-care group later in the study.

Creatinine did not differ significantly between the groups. The study was small and short. The inflammation findings need further confirmation.

These studies examined AIM or individual ingredients. They do not establish that Dr. Toru, Intensive, or their combined use reduces low-grade kidney inflammation.

Open the Capsule. Mix with a Favorite Treat.

Daily care needs to work for your cat—and for you.

Intensive contains a nearly tasteless powder. You can open the capsule and mix the contents with food or a lickable treat.

For a picky cat, try a small amount of a familiar treat. Check that your cat finishes the full portion, including the powder.

Wishing you and your cat many more comfortable days together.

Warm regards,
