topicKefir Mood Meta Analysis
claimMeta-analyses of clinical interventions corroborate the results of regular yogurt or kefir intake, showing significant decreases in fasting glucose, low-density lipoprotein (LDL) cholesterol, and systemic C-reactive protein (CRP) in dysbiosis-associated conditions, with effect sizes dependent on strain composition, dose, and host genotype [,,,].
