Vitamin D3 and its therapeutic potential in pediatric ADHD: a narrative review of clinical outcomes.

Introduction: Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder frequently identified in childhood, marked by symptoms of inattention, hyperactivity, and impulsivity, resulting in functional impairments across diverse life domains. This systematic review investigates the potential advantages of incorporating vitamin D supplementation as an adjunctive therapy for individuals with ADHD. Material and methods: The literature search from 2016 to 2024 using databases like PubMed and Google Scholar focused on studies with high methodological standards and precise ADHD diagnostic criteria. Results and discussion: The results indicate that vitamin D supplementation may improve ADHD symptoms, particularly inattention and hyperactivity/impulsivity. However, the optimal dosage and duration of supplementation remain unclear. While vitamin D appears well-tolerated and safe at studied doses, toxicity can occur with excessive intake. Conclusions: Vitamin D supplementation holds promise as a potentially beneficial adjunctive therapy for alleviating ADHD symptoms, demonstrating safety and tolerability at studied doses. However, further research is crucial to establish standardized protocols and ensure sustained safety and efficacy in the context of ADHD treatment. [ABSTRACT FROM AUTHOR]
