IgY: A Novel Approach to Gut Brain Health

The bidirectional communication network between the gastrointestinal tract and the central nervous system, known as the gut-brain axis, has emerged as a crucial mediator of cognitive function, emotional processing, and overall brain health. This complex system encompasses multiple pathways, including neuronal signaling via the vagus nerve, immune system interactions, endocrine signaling, and metabolite production by the gut microbiota.

This scientific review examines the role of Immunoglobulin Y (IgY), which has been identified as one of the key factors in maintaining gut health through supplementation and thereby has the potential to influence the gut-brain axis. IgY contributes by targeting pathogenic bacteria and their toxins, thus supporting the microbial balance crucial for optimal neuronal, immune, and endocrine functions connected to cognitive and emotional well-being.
