Official title
A Postbiotics Intervention to Improve Cognitive Function in Older Adults With Mild Cognitive Impairment (Phase 1)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This randomized placebo-controlled clinical study, called the LpD3.5 Intervention Study in Older Adults (LISA), aims to evaluate whether a heat-inactivated postbiotic of human origin (LpD3.5) can serve as a non-pharmacological intervention to reduce gut permeability and inflammation in older adults with mild cognitive impairment (MCI). The study will assess the effects of LpD3.5 supplementation on markers associated with gut health, inflammation, microbiome composition, and cognitive function. Participants aged 60 years or older with clinically diagnosed MCI will receive either LpD3.5 capsules or placebo capsules for 60 days, followed by a 30-day follow-up period. Biological samples and clinical assessments will be collected to evaluate changes in gut permeability, inflammatory markers, microbiome characteristics, and cognitive outcomes. The findings from this study may provide insight into the potential role of postbiotics as a dietary intervention to improve gut health and related outcomes in older adults with MCI.
