Galacto-oligosaccharides (GOS) are a non-digestible carbohydrates (prebiotics fibres) made up of galactose units. These units by pass the stomach, small intestine and fermented in the colon.
GOS main role is to grow and colonise a strain of bacteria called bifidobacterium which in turn produce short chain fatty acids called acetate and lactate.
These by products produce butyrate contributing to a healthy mucin barrier next to the gut lining- protecting again pathogens, toxin exposure and LPS producing bacteria’s(‘bad bugs).
Functions of GOS in the Body (via the Gut) include:
1. Improved Digestion & Regularity
* Softens stool, supports bowel movement, and helps with IBS symptoms (especially constipation-predominant IBS).
2. Stronger Immune System
* A balanced microbiome modulates immune responses, lowers inflammation, and helps defend against infections.
3. Better Mineral Absorption
* GOS enhances absorption of key minerals like calcium, magnesium, and iron.
4. Supports Brain-Gut Axis
* By reducing systemic inflammation and producing neuro-active compounds, GOS may support mood and cognitive function.
5. Lower Risk of Chronic Disease
* Anti-inflammatory effects may contribute to lower risks of obesity, type 2 diabetes, and cardiovascular disease.
