The purpose of this study is to investigate the effect of a fermented infant formula on lactose digestion in lactose intolerant adults.

Inclusion Criteria:

BMI between 18.5 and 24.9 kg/m2 inclusive Lactose intolerant

The following criteria need to be checked at visit 2:

• Lactose intolerance confirmed by positive Hydrogen Breath Test (HBT) (i.e. if there are two or more samples with hydrogen level > 20 ppm increase compared to baseline sample between 90 mins and 240 min sampling time point).
• At least one sample with hydrogen level > 20 ppm increase compared to baseline between 90 mins and 180 mins sampling time point.

Exclusion Criteria:

History of gastrointestinal disorders Current illness which could interfere with the study (e.g. diarrhea, regurgitation) Any history of cow's milk protein allergy or known allergy to galacto-oligosaccharides Any current participation or within 8 weeks of study start, in any other study involving investigational or marketed products, any medical procedures, or any surgical methods.

Any antibiotic, laxative or colonic cleansing treatments within 4 weeks of study start Any administration of probiotic in the 1 week prior to study start Investigator's uncertainty about willingness or ability of subject to comply with protocol requirements

The following criteria need to be checked at visit 2:

• Level of hydrogen > 20 ppm in the baseline breath sample.
• An early peak of hydrogen (i.e. hydrogen level > 20 ppm increase compared to baseline value) in the first 60 minutes after ingestion of the study products.

From visit 1 (day -14 to 0) to visit 4 (day 11 to 15)

Adverse events were collected throughout the study period and were documented by Investigator at Visit 2 (Day 1), Visit 3 (Day 6-8), and Visit 4 (Day 11-15).
