Toxin Burden Support for Kidney Health

 Supports your cat’s natural defenses by protecting the first filter—
so toxins stay out of the kidneys before they become a burden.

Why We Made Probiotics Protocol

TT was already receiving focused kidney care,
but her guardian, Claire, kept wondering if there was more she could do.

Not from fear—but from a quiet belief that even small support could help.

That led us deeper into the science of kidney wellness,
where one insight kept surfacing: toxin burden—often missed, but closely tied to kidney stress and probiotic balance.

That’s why we created a probiotic designed to ease that burden before it reaches the kidneys.

Why Guardians Choose Probiotics Protocol

  • Formulated for cats facing hidden internal stress linked to kidney load
  • Supports defenses before toxins burden the kidneys
  • Daily use made easy—even for picky cats
  • Trusted by vets as the missing piece in kidney care

What Makes It Different

  • Targeted for toxin burden—not generic digestion
  • Built with 9 strains selected for internal defense and toxin modulation
  • Backed by clinical insights from CKD-focused veterinarians
  • Can be used safely with Dr. Toru Protocol and Intensive Protocol

Developed with Expert Insight

Dr. Kobayashi Motoo

  • Veterinarian with over 30 years of experience
  • Director, Seijo Kobayashi Animal Hospital (Tokyo)
  • Focused on managing toxin load in cats with advanced kidney disease

Dr. Kim Jae-young

  • Veterinarian & longevity researcher
  • Guardian of Mingki, Korea’s 28-year-old cat

“Mingki had been on probiotics since her youth. I believe this long-term gut care helped her live to 28—even with kidney disease.”

Is This Right for Your Cat?

  • Has lower appetite or energy than usual
  • Is already using Dr. Toru or Intensive Protocol
  • Is showing firm or inconsistent stools—an early sign of internal imbalance
  • May benefit from gentle support to reduce hidden stress on the kidneys

How to Use

  • 1 capsule per day
  • Can be given whole or opened and sprinkled over food
  • For picky eaters, open the capsule and mix with a small amount of food
  • For sensitive cats, start with half and increase gradually

Flexible feeding method—sprinkle or whole
Designed for easy daily use—even with picky eaters

Packaging & Preservation

To preserve potency, Probiotics Protocol uses CSP Active Vials:

  • Blocks moisture, heat, and light
  • Shelf-stable—no refrigeration needed
  • Maintains viability through expiration

Formulation Highlights

Precision-formulated for kidney wellness and microbiome balance.

This synbiotic formula combines 9 probiotic strains with prebiotics (FOS)
to support feline-specific digestion, gut integrity, and toxin burden relief.
Each capsule delivers 2 billion CFU—guaranteed through shelf life, not just at manufacture.

Why it works:

  • Contains FOS prebiotics to feed beneficial bacteria
  • Designed to help probiotics survive and colonize effectively
  • Feline-optimized 2 billion CFU per capsule
  • Stability ensured with CSP vial packaging

How it helps:

  • Supports internal barrier function to reduce toxin-related burden
  • Helps limit reabsorption of waste compounds linked to kidney stress
  • Enhances microbial balance for long-term systemic support

After my cat’s kidney levels went up I was worried about what to do, but I found out about Probiotics Protocl. Even though I started feeding it to my cat for kidney support, it ended up doing wonders for his poop, too! So it’s good for both kidney and gut health! I’ll make sure to keep giving it to my cat!

I read that giving cats probiotics regularly was good for them, so I made sure my cats got them from an early age. I trust Greycoat Research’s products so when they released their new probiotics I switched to that! I’m sure my cats guts will thank me later!

Considering Full Support?

For cats like TT, many guardians choose to combine all three protocols:

  • Dr. Toru Protocol – AIM-based kidney support for natural waste clearance
  • Intensive Protocol – AMPK and antioxidant support for kidney cell health
  • Probiotics Protocol – Toxin burden support to ease kidney load

Together, they target the three most critical areas of kidney wellness for more complete support.

Note on Initial Use

Some cats may experience mild, temporary soft stools during the first 2–3 days of use.
This is a normal adjustment as the gut microbiome adapts to the new strains.
If symptoms persist, reduce the dose and consult your veterinarian.

60-Day Satisfaction Guarantee

Try any product for 60 days.
If you're not satisfied after consistent use, request a full refund—no hassle, no pressure.
