XOS (Xylooligosaccharides)
Also known as: XOS, Prebiotic fibre
A prebiotic fibre that selectively feeds Lactobacillus species, helping them thrive in your gut.
What it is
Xylooligosaccharides (XOS) are a type of prebiotic fibre — food for the beneficial bacteria already living in your gut, rather than a probiotic bacteria itself.
Why we use it
We include XOS in Women's Probiotic Gummies to help support and "feed" the Lactobacillus species in the same formula, so they have a better chance of doing their job.
What the research generally suggests
Research on XOS generally suggests it selectively encourages the growth of beneficial Lactobacillus and Bifidobacterium species in the gut, similar to other well-studied prebiotic fibres, supporting a healthier balance of gut bacteria overall.
Typical amounts
Studies and products commonly use daily amounts in the range of 1-2g, though beauty/wellness gummies often include smaller supportive amounts alongside probiotic strains.
In Flexies products: 100mg per serving.
Benefits
- Lactobacillus fuel
- Microbiome support
- Gut health
Good to know
- • As with most fibres, introducing XOS can cause mild bloating or gas initially in sensitive individuals, which typically settles with continued use.
- • Those with a fructose or FODMAP sensitivity may want to introduce it gradually.
As always, if you're unsure whether this ingredient is right for you, chat to your GP or pharmacist before adding it to your routine.
