Integrating Bone-Brain Axis Modulation and Tea Consumption for Enhancing Neurovascular Resilience and Patient...

Intracerebral hemorrhage (ICH) is one of the most devastating subtypes of stroke, with limited preventive options and a challenging recovery process. This study presents a translational framework that integrates tea polyphenols (TPPs) and exercise-induced metabolites as dual modulators of neurovascular stability, with a focus on patient education for enhancing post-stroke recovery. By synthesizing preclinical and clinical evidence, we demonstrate how TPPs, particularly epigallocatechin gallate (EGCG), and key exercise metabolites such as lactate, β-hydroxybutyrate, and short-chain fatty acids (SCFAs) interact with shared redox-sensitive and inflammatory signaling pathways (Nrf2/NF-κB/AMPK axis) to reinforce endothelial integrity, preserve blood-brain barrier function, and maintain cerebral perfusion. These interventions also reshape the gut microbiota, promoting an SCFA-enriched, anti-inflammatory profile that fosters bidirectional gut-brain communication, further stabilizing vascular homeostasis. Multi-omics evidence suggests that TPPs and exercise metabolites may jointly regulate metabolic and immune pathways, enhancing resilience against oxidative and inflammatory injuries in the vasculature. We propose a mechanistic model in which TPPs and exercise-derived metabolites synergistically support neurovascular function and reduce neurovascular vulnerability associated with ICH, while promoting cognitive recovery and metabolic health. Incorporating these findings into patient rehabilitation education may help individuals make informed decisions about lifestyle changes that enhance vascular health. Future research should explore the dose-response relationship, the optimal timing between tea and exercise, and individual variations, using metabolomic, microbiomic, and imaging biomarkers to personalize cerebrovascular prevention strategies.
