Cellular Survival
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.
Key Ingredients: Balanced with 23 Active Ingredients
Full Ingredient Profile (23 Total)
Resveratrol, Quercetin, Fucoidan, Astragalus, Beta Glucan, L-Carnitine, Taurine, Arginine, Trimethylglycine (TMG), Zinc, Selenium, Magnesium, Thiamine (B1), Riboflavin (B2), Niacinamide (B3), Pantothenic Acid (B5), Pyridoxine (B6), Biotin (B7), Folate (B9), Methylcobalamin (B12), Ascorbic Acid (C), Cholecalciferol (D3), Menaquinone (K2)
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

よくある質問
インテンシブプロトコルを犬に与えてもいいですか?
グレイコートリサーチのインテンシブプロトコルは犬にも与えられるよう設計されています。
犬の体重が10kg以上の場合、1日の推奨投与量が変わるかもしれないので正確な投与方法についてはグレイコートリサーチにお問い合わせください。
猫が健康な状態でもインテンシブプロトコルを与えてもいいですか?

猫にすでに他のサプリメントを与えていますが、インテンシブプロトコルを追加で与えても大丈夫ですか?
インテンシブプロトコルは大部分の乳酸菌、オメガ3、リン吸着薬と一緒に与えることが可能です。しかし猫がどんなサプリメントを摂取しているのかによって与える方法が変わってきます。いくらいい成分でも過多摂取は猫に負担になりえるので有効成分の容量の調節が必要です。
インテンシブプロトコルを初めて与える場合、猫の健康の状態と服用中の治療薬およびサプリメント情報をお送りくだされば、適切なインテンシブプロトコルの服用方法をお知らせします。
Dr.Toruプロトコルとインテンシブプロトコルを同時に与えても大丈夫ですか?
はい。猫にDr.Toruプロトコルとインテンシブプロトコルを同時に与えられます。ただしDr.Toruプロトコルにはアミノ酸が含有されているので、食事や間食の時間に一緒に与えることを推奨します。一方インテンシブプロトコルはいつでも与えることができます。
インテンシブプロトコルの有効期限はいつですか?
製造日から2年です。
