Language processing is a sophisticated cognitive activity supported by dynamic interactions within extensive brain networks. Recent interdisciplinary research suggests that vitamin D, in addition to its traditional role in calcium regulation, may also influence brain function by modulating neuronal excitability, synaptic plasticity, and neurotransmission. The precise effect of vitamin D insufficiency on the neurodynamic structure of language is yet inadequately comprehended. This study intends to rigorously analyze the correlation between vitamin D levels and the oscillatory and connective characteristics of language-related neural networks through a narrative and critical review methodology. Literature was obtained from prominent scientific databases and evaluated thematically, concentrating on molecular processes, brain oscillations, and functional connections. The results demonstrate that vitamin D insufficiency correlates with decreased beta and gamma oscillatory power, reduced theta coherence, and impaired functional connectivity between critical language regions, including Broca’s and Wernicke’s areas. These disruptions indicate a deviation from optimal brain rhythms, which may hinder linguistic integration and predictive processing. The study emphasizes the need for longitudinal and interventional investigations, combined with computational modeling based on neurophysics, to further clarify these pathways. These discoveries enhance the understanding of how systemic biological variables influence cognitive networks and may guide future efforts for the early detection and intervention of language-related illnesses.
