How it works
Most deodorants fight bacteria. Ours works with your skin.
- Control – zinc and sodium bicarbonate help neutralise the compounds behind unwanted odour, without stripping your microbiome.
- Balance – prebiotics feed the good bacteria, so they naturally outcompete the odour-causing strains.
- Care – aloe vera and antioxidant-rich extracts help soothe and support your underarm microbiome.

Aluminium salts and animal-derived ingredients. Fresh aloe and cucumber scent.
Prebiotic Deodorant
Most deodorants fight your bacteria.
Ours feeds the good ones.
The old approach
Conventional deodorants block pores with aluminium salts and wipe out bacteria, good and bad, so odour comes straight back.
The Gutology way
A prebiotic formula that helps the good bacteria thrive and outcompete the odour-causing ones, with zinc and sodium bicarbonate to neutralise odour. In a refillable, recyclable aluminium bottle.
What's inside
No proprietary blends. No hidden fillers.
Full transparency, always.

What to expect when switching?
Most people go through a 2–4 week adjustment period. You may sweat a little more or notice some odour at first while your skin rebalances – this is temporary.
Conventional deodorants use aluminium to block your pores, so your body needs time to adjust, and our prebiotic formula takes time to rebalance your underarm microbiome.
-
Top tips
- Give it time: stick with it for at least a month.
- Reapply when needed: it's a deodorant, not an antiperspirant, so you won't stop sweating completely. Reapplying mid-day is normal, especially in hot weather or after exercise.
-
How long does one bottle last?
The 40ml bottle is a concentrated formula. Used like a standard deodorant, it typically lasts around 4–6 weeks.
-
Is it suitable for sensitive skin?
The formula is designed to be gentle, but skin varies. If you have sensitive skin, patch test on the inside of your arm first. If you notice redness, itching or irritation, stop using it and speak to a GP or dermatologist. Don’t use it if you’re allergic to any of the ingredients.
-
How should I store it?
- Keep it in a cool, dry place, away from direct sunlight.
- Store upright with the lid screwed on.
- Avoid very hot spots like windowsills or car dashboards.
-
Can I use it while pregnant or breastfeeding?
We’d always recommend checking with your GP or midwife before introducing new personal care products, especially because of the essential oils in the fragrance.
-
Why is the bottle aluminium?
Aluminium can be recycled again and again with no loss of quality. The bottle is designed to be kept and refilled, so there’s less packaging waste with every reorder.
