Neuro-nutraceuticals: The path to brain health via nourishment is not so distant

In this Special Issue on "Nutraceuticals: Molecular and Functional Insights into how Natural Products Nourish the Brain", the editors bring together contributions from experts in nutraceutical research to provide a contemporary overview of how select chemically identified molecules can beneficially affect brain function at the molecular level. Other contributions address key emergent issues such as bioavailability, formulation, blood brain permeability, neuronal health and inflammation that impact upon how nutraceuticals ultimately leverage the brain to function better. Whilst nutraceutical is used as marketing term, it has no regulatory definition, and there is a continuing need for licensing authorities to ensure that adequate guidelines exist pertinent to the safety to guide consumers internationally. In terms of the benefit of nutraceuticals is it clear that some naturally occurring molecules can be advantageous to both the young and aged brain, and that they have actions that ultimately can be directed to aid either in the improvement of cognition or in the management of debilitating neurodegenerative and neuropsychiatric conditions.
