Biotis® GOS (Galacto-Oligosaccharides — FrieslandCampina)

Evidence Level
Moderate
1 Clinical Trial
3 Documented Benefits
3/5 Evidence Score

Biotis® GOS is a galacto-oligosaccharide prebiotic from FrieslandCampina, a fiber that mimics the oligosaccharides naturally found in milk. GOS is selectively fermented by beneficial gut bacteria, especially bifidobacteria, and is studied for supporting regularity, stool consistency, and a healthier microbiome.

Studied Dose Commonly a few grams per day.
Active Compound Galacto-oligosaccharides (GOS), non-digestible prebiotic fibers produced enzymatically from lactose.

Benefits

Regularity and stool comfort

In a controlled study, GOS supplementation improved stool frequency and supported comfortable, regular bowel movements.

Supported by Trial 1

Bifidobacteria support

GOS is selectively fermented by beneficial bifidobacteria, helping shift the microbiome toward a healthier profile.

Digestive and immune balance

By feeding good bacteria and boosting short-chain fatty acids, GOS supports the gut barrier and the immune tissue that lines it.

Supported by Trial 1

Mechanism of action

1

Selective bifidogenic fermentation

Bifidobacteria preferentially ferment GOS, producing short-chain fatty acids and lowering gut pH, which favors beneficial species.

2

Stool bulking and hydration

As a soluble fiber, GOS draws water into the stool and adds microbial mass, supporting regularity.

Clinical trials

1
Galacto-Oligosaccharides and Stool Frequency — Study
PubMed

Controlled study of prebiotic galacto-oligosaccharides on stool frequency and fecal microbiota. (Schoemaker et al. 2022, Nutrients)

Adults.

GOS supplementation improved stool frequency and beneficially affected the fecal microbiota, supporting its use for regularity and gut balance.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated as a prebiotic fiber.
Mild gas or bloating can occur as intake increases.
Made from lactose but largely lactose-free; very sensitive individuals should start low.

Important Drug interactions

No significant drug interactions are established.
Introduce slowly if you have IBS or are FODMAP-sensitive.
Tell your doctor if you have a serious digestive condition.
