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*

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

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

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

If your digestion changed in your 40s — more bloating, less regularity, a stomach that looks different by the afternoon — you're not imagining it, and you're not doing anything wrong.

Your gut is directly linked to your hormones. As oestrogen declines through perimenopause and menopause, your gut slows down, the good bacteria thin out, and the gut lining gets more easily irritated.

This is a normal biological shift — it happens to most women. The good news: support the gut the right way and it responds. That's the whole idea behind GutBio.
