| contents | Stroke is a leading cause of disability and death worldwide, with ischemic strokes accounting for nearly 80% of cases. Fewer than 5% of patients receive the sole validated pharmacotherapy, intravenous thrombolysis, highlighting the urgent need for novel therapies. Within this landscape, the exploration of natural molecules emerges as a promising avenue, particularly as a means to address limitations associated with conventional drugs. Nutraceuticals, bioactive compounds derived from food sources, offer a compelling prospect for health and wellness. The term nutraceutical reflects their dual potential in nutrition and pharmacotherapy, emphasizing their relevance to both disease prevention and treatment. Interestingly, many were initially recognized as ''natural preconditioners'', substances that prime the body for protection against stress or damage. In fact, numerous nutraceuticals have been shown to activate protective pathways similar to those triggered by preconditioning across various organs. Among nutraceuticals, omega-3 polyunsaturated fatty acids sourced from plants or fish, along with polyphenols, have emerged as particularly promising. Their consumption has been associated with a reduced risk of ischemic stroke, supported by numerous preclinical studies demonstrating their beneficial effects on cellular components within the neurovascular unit. This review explores the shared protective mechanisms of various nutraceuticals against key drivers of ischemic injury, including excitotoxicity, oxidative stress, apoptosis, and inflammation. By delineating these actions, the review highlights the potential of nutraceuticals as brain preconditioners that enhance neuroprotection, thereby mitigating the impact of cerebral ischemia in both preventive and therapeutic contexts. |
