Several studies show that Biotis GOS positively influence the microbiota,

In one clinical study with elderly adults, participants were given 9g/Biotis® GOS per day in a yoghurt, with a placebo group consuming yoghurt without added GOS. Over the two-week trial period, Biotis® GOS showed increased defecation frequency and ease in the defecation process compared to the control group.

A later study reinforces the effects of Biotis® GOS on constipation in elderly adults. Participants with self-reported constipation were randomised to receive either a placebo or a Biotis® GOS dose of 12g/day in a yoghurt with prunes and linseeds. Consumption of Biotis® GOS supplemented yoghurt was shown to reduce the severity of constipation.
GOS has also been shown to hold potential benefits for sufferers of irritable bowel syndrome (IBS).
A meta-analysis of 11 studies investigated the impact of prebiotics on gastrointestinal symptoms in adults with IBS or functional bowel disorders. The results found that non-inulin type fructans such as GOS can potentially reduce flatulence and bloating.
