Microbiome-based dietary supplements for better development and healthy brain.

Microbiome-based dietary supplements have gained attention for their role in enhancing brain development and cognitive health. The gut microbiome influences neurological functions through the gut-brain axis, impacting neurotransmitter production, immune regulation, and metabolic pathways. Dysbiosis is linked to neurological disorders such as Alzheimer's, Parkinson's, and autism spectrum disorders. This chapter explores dietary interventions targeting the microbiome, emphasising probiotics, prebiotics, and postbiotics. Additionally, AI and machine learning are transforming microbiome research by enabling personalised supplementation strategies tailored to individual gut profiles. Ethical challenges, including data privacy and algorithmic bias, are also discussed. Advances in big data analytics and predictive modelling are paving the way for precision-targeted interventions to optimise brain health. While microbiome-based therapies hold great promise, further clinical validation and regulatory frameworks are needed to ensure their efficacy and accessibility. This chapter highlights the future potential of microbiome-targeted strategies in neuroprotection and cognitive well-being.
