Gut enterotype- and body mass index (BMI)-dependent effects of anthocyanin supplementation on gut microbiota composition in individuals at risk for cognitive decline: A randomized placebo-controlled trial
This study will investigate the effects of anthocyanin supplementation (capsules containing naturally purified anthocyanins from bilberry (Vaccinium myrtillus) and black currant (Ribes nigrum)) on microbiome composition over a 24-week randomized, double-blind, placebo-controlled Phase II trial in a Norwegian cohort. Specifically, it will investigate how baseline microbiome composition, along with intrinsic factors like BMI and age, mediate the microbiome's response to anthocyanin supplementation, aiming to provide insights for more effective, personalized dietary interventions.
