Our Story

Gut health starts in the mouth.

Most people think about gut health from the stomach down. We started one step earlier.

Every time you swallow — about 600 times a day — bacteria from your mouth travel to your gut. For years, the conversation around gut health has focused entirely on what happens once bacteria reach the intestines. Nobody was looking at what was being sent there in the first place.

The oral microbiome is the second most diverse microbial environment in the human body, after the gut. The two are connected by a single pathway: every swallow. When the bacteria making that journey are out of balance, they don't just affect your mouth. They seed dysbiosis in the gut, trigger inflammation, and undermine the very probiotics you're taking to fix things downstream.

We built Arbor because that gap was real, the science was clear, and no Australian brand was standing in it.

The woman who found us

She'd been doing everything right. The Seed probiotic. The morning routine. The clean diet. The naturopath appointments. And still — something wasn't quite clicking. Her gut felt almost-right. Her breath came back by afternoon. Her gums bled a little when she brushed and she'd learned to ignore it.

Nobody had told her that her mouth was sending bacteria to her gut 600 times a day. Not her GP, not her dentist, not the practitioners she trusted.

Arbor exists to close that gap. One chewable tablet, taken nightly, that starts where the gut actually starts.

What we believe

We believe the body is a connected system, not a collection of separate parts. We believe the mouth deserves the same care as the gut. We believe in showing people what's in the product and why — and what's not in it. We believe the woman who has tried everything deserves something that starts somewhere new.
