Daily GLP-1 support for dogs
Your dog's metabolic health begins with GLP-1
G-Loop™ is a daily supplement that supports your dog's own GLP-1 signaling, starting in the gut.*
What better metabolic health looks like
Healthy digestion, a healthy weight, and the vitality to keep up with you. G-Loop™ supports your dog's gut, metabolic, and cellular health every day.* For best results, we recommend at least 90 days of daily use.
Healthy digestion
Balanced gut bacteria
A healthy weight
Healthy cells
Vitality and mobility
We look after our own metabolic health. What about our dogs'?
The science of healthy aging keeps pointing to metabolic health, in people and in dogs. Our dogs deserve that same support, every day, long before anything shows.
657 more days
In Purina's Life Span Study, Labradors kept lean for life lived longer: 657 more days, at the median. Researchers tied the difference to the lean dogs' healthier metabolism.
12 hallmarks of aging
Scientists group the biology of aging into 12 hallmarks. All 12 are closely connected to one another. Two of them, nutrient sensing and gut balance, tie directly to GLP-1.

Meet G-Loop™
Pre-measured for your dog
Every stick includes clinically tested ERIOMIN®, measured to your dog's weight: 35, 70, or 105 mg. Pick the one that suits your dog, and serve one stick a day.
How it works
Care starts at the molecular level
Every mammal makes GLP-1, your dog included. It’s a signal that helps keep core systems functioning normally. G-Loop™ supports it every day, starting in the gut.*
Gut health
G-Loop™ feeds the gut bacteria that help your dog release GLP-1, a natural hormone every dog already makes.*
Metabolic health
GLP-1 helps coordinate your dog's digestion, energy, and metabolism, so food becomes steady fuel.*
Cellular health
G-Loop™ supports cellular health, so your dog's body keeps renewing, from the puppy years to the gray muzzle.*
Why it works
Powered by ERIOMIN®
ERIOMIN® is a flavonoid with a decade of human research behind it. In placebo-controlled human trials, it raised active GLP-1.
Dogs have the same gut cells and the same GLP-1 signaling. That's why we built G-Loop™ around it.
Inside every stick
Gives gut bacteria the raw material they turn into a GLP-1 signal.*
Feed the gut bacteria that turn ERIOMIN® into the GLP-1 signal.
Add good bacteria to the gut and help keep those populations strong.
Carry the signal itself, and help hold the gut barrier together.*
