What is Arbor?

Arbor is an oral probiotic — a chewable tablet taken nightly that repopulates your oral microbiome with clinically studied strains to support fresh breath, gum health, and the bacteria that travel from your mouth to your gut every time you swallow.

Format Slow-dissolve chewable tablet
Flavour Refreshing mint
View Supplement Label

Supports:

  • Oral microbiome balance
  • Fresh breath
  • Gum health
  • Enamel protection
  • Gut-oral connection
Directions for use

Chew or dissolve one tablet on your tongue before bed. Take nightly for best results. Avoid eating or drinking for 30 minutes after use — the strains need time to colonise. One tablet per night is enough.

Frequently asked questions

What is Arbor, exactly?
Arbor is an oral probiotic — a chewable tablet taken nightly that repopulates your oral microbiome with strains that support fresh breath, gum health, and a cleaner bacterial pathway from your mouth to your gut. Every time you swallow, you send bacteria from your mouth to your gut. Arbor makes sure you're sending the right ones.
How is it different from a gut probiotic like Seed?
A gut probiotic is designed for the intestinal environment. The strains are chosen to survive the stomach and colonise the large intestine. Arbor is formulated specifically for the oral environment. The strains it contains are selected to survive and colonise in your mouth — which is where your gut actually begins. They are not the same strains, not the same formulation, and not designed for the same place. They work together, not instead of each other.
When will I notice a difference?
Most customers notice a difference in morning breath within 3–4 weeks. Gum health tends to improve earlier — typically within 1–2 weeks. For deeper gut benefits, allow 60–90 days of consistent nightly use. The benefits compound over time: customers who have been using Arbor for 6–12 months report outcomes they didn't expect from an oral probiotic.
How do I take it?
Chew or dissolve one tablet on your tongue before bed. Take it nightly. Avoid eating or drinking for 30 minutes after — the strains need time to colonise without being washed away. Most customers add it to the end of their evening routine, right before sleep.
Is Arbor made in Australia?
Yes. Arbor is manufactured in Australia to the highest quality and safety standards. Made with naturally sourced ingredients, no artificial colours or sweeteners, and no fillers.
What is your returns policy?
We offer a 30-day money-back guarantee. If you don't notice a difference in your first month, contact us and we'll refund your order in full — no questions asked. We're that confident in what Arbor does.

"I forgot to buy breath mints and didn't notice for a week."

I've been taking a gut probiotic for two years, eating clean, doing everything right. Within three weeks of starting Arbor, I realised I'd run out of breath mints and genuinely hadn't noticed. That's when I knew something had actually changed.

"My hygienist asked what I'd changed."

After about six weeks, I went in for a clean and she said my gums looked so much healthier. I'd had bleeding gums for years. She thought I'd started a new dental routine. The only thing different was Arbor.

"The piece that was missing from my whole wellness stack."

I take Seed. I take AG1. I've spent years trying to fix my gut from every angle. I didn't realise I'd been starting in the wrong place. Since adding Arbor, everything else seems to work better.

"A different mouth by morning."

I was so desperate after trying every mouthwash, every prescription rinse, everything. Nothing lasted more than an hour. Now I wake up and my mouth just feels clean — like I brushed right before I slept.

"My gut responded when my mouth did."

I bought this for morning breath. I wasn't expecting the gut benefit. But my bloating has reduced significantly and my digestion is noticeably more settled. I had no idea my mouth had anything to do with it.
