Nutritional inadequacies, including low dietary fibre intake and suboptimal B-vitamin status, are common in older adults and may contribute to these age-related health issues. Research suggests that increasing dietary fibre intake, particularly through prebiotics such as inulin, may help to improve gut health. In addition, B-vitamins have been linked to both gut and mental health, although their combined effects with prebiotics are not well understood.\n\nWith the assistance of a food company, the investigators have developed a functional drink enriched with chicory inulin, alone or in combination with B-vitamins. Therefore, the investigators plan to conduct a 12-week randomised, double-blind, placebo-controlled trial to test the effect of this functional drink on gut health outcomes, nutritional status, inflammation, and mental health in adults aged 50 years and older.",[90],"Biomarkers of B-vitamin Status and Gut Microbiome Composition",[92,93,94,95,29],"Functional food","Healthy ageing","B-vitamin status","Gut microbes","2026-05-11",{"date":98,"type":99},"2026-05-18","ACTUAL",{"date":98,"type":84},{"date":102,"type":84},"2026-12",{"name":5,"class":6},1]
