Why replace your current mouthwash?

  • Microbiome-friendly

    Liquid Biome+ is microbiome-friendly, using prebiotics to support microbiome balance without the harsh chemicals found in traditional mouthwash.

  • Reinforcing, not stripping

    Powered by hydroxyapatite a science-backed mineral that helps protect enamel and support the mouth’s natural mineral balance.

  • Fluoride-free by design

    We chose a different approach - Formulating with hydroxyapatite, a gentle mineral that works in harmony with your mouth’s natural biology.

  • Think beyond the big brands

    Many high street formulas use detergents and alcohol-based antiseptics that may disrupt the oral microbiome.

  • Bad breath?

    Unlike harsh rinses that just mask it, Liquid Biome+ supports a balanced oral microbiome a key factor in long-lasting freshness.

  • Oral health goes beyond the mouth

    The oral microbiome is closely connected to the rest of the body including your digestive system. Liquid Biome+ is designed to support balance at the gateway to it all.

Rethinking mouthwash

Most high street mouthwashes contain harsh ingredients like alcohol, chlorhexidine, and triclosan designed to eliminate bacteria without considering the balance of your oral microbiome.

While these ingredients may temporarily reduce plaque or freshen breath, they can also disrupt the helpful microbes that play a vital role in maintaining long-term oral harmony.

Gutology’s approach is different. Liquid Biome+ is formulated with ingredients like hydroxyapatite and prebiotics, designed to work with your body, not against it. Just a gentler, microbiome-aware step in your daily routine.

The future is prebiotics

Prebiotics are ideal for mouthwash because they deliver the functional benefits of microbiome science by selectively nourishing beneficial bacteria.

These nutrients, such as fibres and oligosaccharides, have been studied for how they interact with the oral microbiome and promote microbial balance.

Unlike traditional antimicrobials, prebiotics support the environment that allows protective species to thrive. They’re stable, well-tolerated, and perfectly suited for daily oral care where balance not sterilisation is the goal.

The Power of Hydroxyapatite

Hydroxyapatite is a biocompatible mineral that closely reflects the natural structure of enamel.

It helps support a more balanced, mineral-rich surface environment without disrupting the oral microbiome.

Sometimes, science feels a little like magic.

  2. Swish
    Swish the mixture thoroughly around your mouth for 30 seconds.

Love the mouthwash

2nd purchase, now with a pump dispenser it’s even better!

Great product poor packaging

This is a honest view on my experience. The mouth wash is good but the bottle is not great. It’s very difficult to **** the cap back on and takes many tries. My husband gave up but didn’t tell me! I shook the bottle up has your supposed to and ended up losing half a bottle all over me and the bathroom. The little cup it comes with is nice but the markings are difficult to see I decided to change the top to a pump. This is also a more accurate measurement than just guessing. Maybe go back to the drawing board on the packaging.

Hi Alison,

Thank you so much for your honest review, we're really sorry for any inconveniences caused. This is our very first version of Liquid Biome+, so feedback like yours is incredibly valuable as we work to improve.

We’ve already sent you a separate email with a little surprise inside, and truly appreciate you taking the time to share your experience.

Excellent mouthwash, I use the toothpaste as well. I saw an improvement within a week. I would buy both products again. They are far better and healthier than the products on the shelf, good price too

The product itself is good but container is poor I had three now that leak I can't take them away with me the latest container doesn't even **** and the plastic pipe has come away

No improvement to my gum disease.

At the recommended dilution rate I find it rather strong and therefore have to use less. It leaves your mouth feeling fresh, but other than that I have not notices any difference. I still have gum disease and that has not improved since taking this 3 month and therefore now wondering if it has any real benefit.

Bloke has better breath

Bought this for my bloke, who has frequent bad breath from bacteria in a "pocket" of his gums.
Works a treat, and without the overpowering alcoholic stink he used to come to bed with after using mass-produced mouthwash.
You dilute it heavily to use, so it doesn't work out as expensive as it looks.

I like how my teeth feel after using

Only been using a short time, but I like how my teeth feel after using. My only complaint is the bottle/pump. Not sure if I have a faulty one, but I'm having a nightmare with the contents leaking out through the **** part of the pump dispenser (not out of the nozzle). It's screwed on as tight as it can go, but every night I've got leaked contents running down the sides of the bottle and have to do a clean up because it's really sticky.

It’s ok….

It’s ok, would be better if you didn’t have to measure it out and then dilute it. Also, mine leaks from the top and makes it very sticky

I really appreciate all the research of this

I really appreciate all the research done to make this this mouthwash, I feel as if I'm helping restore the natural balance of my mouth instead of killing everything with chemicals and alcohol.
I am definitely going to try the toothpaste with my next order.
Thank you & keep up the good work.

Gutology Liquid Biome

Only a week in so not really able to tell in having any benificial effects yet. I am find it rather strong, even diluted at the stated ratio, but that's just my personal opinion. Because the container and top are both Aluminium and the **** thread is rather course, it is rather a loose fit and liquid tends to leak from the thread both when shaking the bottle and afterwards. I will keep on with it and see how it goes after another few weeks when I have a Dentist's appointment and see if he makes any comment.

I like the product, it is expensive but lasts a while. I would prefer it if it was ready to use as it is difficult to see the doseage on the measuring cup.

Only two weeks in

Pleasant taste, but too soon to tell whether it is better than the alternatives. I will give it, and the toothpaste a three month trial after my scientist daughter recommended them to me.

Only been using for a short time

I haven’t noticed any difference yet but it has a pleasant taste. I like the idea of diluting it. It would be nice if their was a marker inside the cup though but 2 squirts seems about right

Ticks all the boxes

I was pleased the mouthwash was concentrated and not a lot was needed otherwise it would be quite expensive. It’s refreshing with a minty taste which leaves my mouth feeling refreshed. It’s in a convenient easy to use container.

Great taste and clean feel

The mouthwash is concentrated and goes a long way . It leaves you whole mouth feeling fresh and clean. With a light minty flavour which doesn't overpower !
