The effect of this formula will be compared to a placebo after 8 weeks of consumption.

Enrollment: 116 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Men and women aged 18-65 years

• Body Mass Index (BMI) 18.5 - 30.0 kg/m2 (limits included)

• Otherwise healthy subjects with Postprandial Distress Syndrome (PDS) as defined by ROME IV criteria: Must include one or both of the following criteria* at least 3 days a week: - Bothersome postprandial fullness (i.e. severe enough to impact on usual activities)

• Bothersome early satiation (i.e. severe enough to prevent finishing a regular size meal)

  *Criteria fulfilled for the last 3 months with symptom onset at least 6 months prior to diagnosis with no apparent evidence of organic, systemic or metabolic disease or structural disease by standard clinical examination by the investigator at V0 that is likely to explain the complaints

• Documented Helicobacter pylori negative subjects according to a validated previous test (histological, breath, stool antigen or serological test) in the last 5 years or if not, with a rapid assay realized during V0

• Negative urine pregnancy test for women in childbearing age at V0 At V1, after 1-week diary completion, mean "PDS score" on LPDS scale ≥ 1 and <3 (mild and moderate) As per this randomization criterion, any subjects with a "PDS score" of ≥3 (severe or very severe) or <1 (too low) at V1 will be withdrawn from the study.

For assessment of PDS, the last 7 consecutive days before V1 should be used to calculate the score.
