Brief Summary
The goal of this study is to investigate if a food ingredient can improve stress in healthy adults who experience moderate symptoms of self-reported stress. The main question it aims to answer is if 4 weeks of daily intake of the ingredient reduces stress compared to 4 weeks of daily intake of a placebo product. Participants will:
- consume both the test and placebo products for 4-weeks each in a randomised order, with 4 weeks in between
- visit the test site 6 times over the 13 weeks
- complete a series of assessments on stress and sleep quality and provide blood, stool and saliva samples

Outcome Measures
Primary Outcomes (1)
Change in Perceived Stress Scale (PSS) Total Score from baseline to end of intervention
The PSS is a self-reported measure of stress. The questions in this scale ask about participants feelings and thoughts during the last month. Respondents are asked how often they felt a certain way on a five-point scale from 'never' to 'very often'. It is a 10-item questionnaire and has a total score which correlates with one of three score categories (low stress \[0-13\], moderate stress \[14-26\]and high stress

- Use of any intrauterine device (IUD) or contraceptive implant. The Participant must have the device inserted at least two weeks prior to the first screening visit, throughout the study, and two weeks following the end of the study.
- Is hypersensitive to any of the components of the Study Product.
- Have a significant acute or chronic coexisting illness such as such as uncontrolled hypertension, type 1 or 2 diabetes, cardiovascular diseases or any condition which may, in the opinion of the investigator, impact their ability to participate in the study or impact the study outcomes.
