Frequently asked questions

GLP-1 (glucagon-like peptide-1) is a natural hormone made in the gut, in dogs and in people. It helps coordinate metabolism, energy balance, and digestion.*

No. GLP-1 is a hormone your dog already makes in the gut when they eat. It helps coordinate digestion, energy, and metabolism.* G-Loop™ does not contain GLP-1 or synthetic GLP-1 and is not a GLP-1 agonist drug. It's a daily supplement that supports your dog's own GLP-1 signaling.*

G-Loop™ is not a weight-loss supplement. It's formulated to support healthy weight management as part of daily care. No supplement makes up for extra treats, so your part still matters.

Because metabolic health is quiet, and a dog can look and act well long before anything shows. G-Loop™ supports your dog's own GLP-1 signaling every day, so you're caring for their metabolic health from the start, not once something seems off.*

G-Loop™ is a daily supplement for dogs. It supports your dog's internal systems, including digestion, energy, and metabolism, to help them feel their best from the inside out.

It works with your dog's own GLP-1, starting in the gut. ERIOMIN® and prebiotics feed your dog's gut bacteria. The bacteria turn ERIOMIN® into short-chain fatty acids, and those acids signal the gut lining to release GLP-1.* The probiotic and postbiotic help keep the gut ready to do that work.*

A probiotic adds helpful microbes. G-Loop™ has one, plus a prebiotic and a postbiotic. It also has ERIOMIN®, which gives gut bacteria the raw material they turn into a GLP-1 signal.* So it supports gut health and the metabolic signaling that starts there.*

Choose by your dog's weight. Small is for dogs up to 25 lbs, Medium for 26–75 lbs, and Large for over 75 lbs. Bigger dogs get more ERIOMIN® in every stick: 35, 70, or 105 mg. Each box holds 30 stick packs, one a day.

Sprinkle one stick over your dog's meal each day and mix it into wet or dry food. Add water if you like. No scoops, no pills, no mess.

Every dog is different. We recommend at least 90 days of daily use, because G-Loop™ works with your dog's own systems over time.*

G-Loop™ is formulated specifically for dogs and made with clinically tested ERIOMIN®. It's manufactured under strict quality standards. If your dog takes medication or has a health condition, check with your vet first.

G-Loop™ is made to be served with your dog's regular food. If your dog takes medication or has a health condition, check with your vet first.

Whole citrus fruits (like lemons) can irritate dogs, but G-Loop™ uses purified citrus bioflavonoids, not oils or acids. It's formulated to complement your dog's biology and help keep everything in balance.

ERIOMIN® is a clinically tested citrus bioflavonoid with a decade of human research behind it, including three trials that showed higher GLP-1. It's made by Ingredients by Nature, the company of PETNUTRA founder Rob Brewster, and PETNUTRA holds the exclusive rights to bring it outside human health.

Not yet. The research on ERIOMIN® today is in people: three human trials, each showing higher GLP-1. Dogs share the same GLP-1 system, which is why we built G-Loop™ around it. We share the human results as our reason, not as dog results.

The published ERIOMIN® studies are linked on How it works, under "Studied in people. Built for dogs." Each one opens on the journal's site.
