Where Gut Science Meets the Belly Rub.
Clinically dosed, third-party tested wellness for dogs and cats — engineered around the gut, the organ that governs immunity, mobility, coat, and longevity.
What shows up in the bowl first.
Gut & Digestion
Soft stools, gas, or a half-finished bowl — collagen peptides help rebuild the gut lining they eat on.
Settle their tummy
Calm & Stress
Restless nights and clingy days often track with gut discomfort. Glycine supports the gut–brain loop.
Support daily calm
Hip & Mobility
Stiffness after naps isn’t only age — gut inflammation feeds joints. Collagen and glucosamine in every pour.
Ease their joints
Skin & Coat
Itchy paws and a dull coat often start in the gut. Better absorption shows up in their fur first.
Brighten their coat
Allergy & Immunity
Scratching, sniffles, slow recovery — most immune cells live in the gut. Start support there.
Build immune resilienceMost pet supplements are marketing, not medicine.
The category runs on soft claims and softer doses. We built BELLYLAB to be the opposite of that — auditable, clinically dosed, and honest about what's inside.
Typical pet supplements vs. clinically dosed BELLYLAB — same serving size.

★★★★★"Finally a supplement brand that shows the actual doses. I compared the label to published studies — it checks out."
★★★★★"Miso was a picky eater until we started the bone broth. Her coat is softer and she seems more comfortable after meals."
