What's really going on

It’s not your diet. It’s a natural shift in your gut.

More stomach discomfort, less regularity, a stomach that looks different by the afternoon, if this started in your 40s, you’re not imagining it, and you’re not doing anything wrong.

Your gut is closely linked to your hormones. As oestrogen naturally declines through perimenopause and menopause, digestion can slow, the balance of good bacteria can shift, and the gut can feel more sensitive.

This is a normal part of getting older, it happens to most women. The encouraging part: support your gut well, and it tends to respond. That’s the whole idea behind GutBio.

The gut-after-40 shift
1 · Oestrogen naturally declines
Hormone levels shift through peri & menopause.
2 · Digestion can slow, balance can shift
Less diversity, slower movement, a more sensitive gut.
3 · Bloating & irregularity
The discomfort that can seem to appear from nowhere.

The science, simply

What are CFUs?

CFUs (Colony Forming Units) measure the live, active bacteria inside a probiotic — the "population count" of beneficial bacteria ready to get to work in your gut. For women, a higher CFU count means more good bacteria reach the digestive tract to rebalance gut flora, help digestion, and help support a balanced gut microbiome*

GutBio probiotic kombucha gummies for everyday gut health
Less bloating

Enough CFUs help restore balance when gut flora is off — so digestion can feel more comfortable*

Gentle regularity

Healthy gut bacteria support regular movements, so you feel lighter**

Built for women

The right strains and plenty of CFUs make a noticeable difference for women's gut and overall balance.*

Questions, answered

Frequently asked

When will I start to notice results? +

Many women feel a difference within 2 weeks, lighter, more regular, less of that heavy afternoon feeling. Your gut microbiome takes around 60–90 days to fully settle, which is why we suggest the 3-bag reset and why the guarantee covers a full 60 days. Give your gut the time it needs.*

 I’ve tried probiotics before and didn’t notice much. Why might GutBio be different? +

Many probiotics use strains not chosen with women 40+ in mind, and often leave out the prebiotics and postbiotics that help them work. GutBio pairs live kombucha cultures with a prebiotic to feed them and a postbiotic to support the gut, a complete daily system, backed by the 60-day buyback so you can try it with confidence.

Will it suit me, at my age? +

GutBio is designed around the gut changes that come with perimenopause and menopause, so it’s made with women 40+ in mind. Everyone’s different, which is exactly why the 60-day buyback exists — so you can find out for yourself without the risk.

Why a gummy instead of a capsule? Is it as good? +

The best supplement is the one you actually take every day. A berry-flavoured gummy you enjoy tends to become a habit, where a capsule you dread gets skipped. GutBio’s kombucha base delivers live cultures in a fermented form your gut recognises.

 I could just drink kombucha, why buy this? +

Bottled kombucha varies a lot in live cultures, tends to be high in sugar, tastes sharp, and needs refrigerating. It also doesn’t include Slippery Elm Bark, Dandelion Root or a postbiotic. GutBio gives you a complete daily gut-support system in one berry gummy, no vinegar, no fridge.

How do I take it, and can I take it alongside other supplements? +

One to two gummies a day, ideally in the morning. GutBio is a food supplement made from natural ingredients and suits most adults. If you’re pregnant, nursing, or taking prescription medication, check with your GP first.

Are the gummies vegan and suitable for everyday use? +

Yes, vegan, gluten-free, non-GMO, and free from artificial colours, flavours and preservatives. Designed as a daily gummy you can take every day.
