Abstract

Diabetic anemia is a common and often under-recognized complication of diabetes mellitus, characterized by 
impaired erythropoiesis, reduced erythropoietin production, and systemic oxidative stress. This condition not only 
compromises oxygen delivery to peripheral tissues but also exacerbates neurodegenerative changes, contributing to 
cognitive decline and heightened vulnerability to neural dysfunction. Natural product-based antioxidants, including 
polyphenols, flavonoids, carotenoids, and terpenoids, have emerged as promising therapeutic agents due to their 
dual capacity to mitigate oxidative damage and modulate key signaling pathways involved in erythroid and neuronal 
health. These compounds act by scavenging reactive oxygen and nitrogen species, enhancing endogenous 
antioxidant defenses, stabilizing mitochondrial function, and regulating hypoxia-inducible factors to promote 
erythropoietin synthesis. Additionally, they exert neuroprotective effects by activating the Nrf2 pathway, reducing 
neuroinflammation, and preserving synaptic integrity. This review provides a comprehensive overview of the 
molecular mechanisms through which natural antioxidants influence erythropoiesis and neural function in the 
context of diabetes-induced anemia. We also discuss translational and clinical perspectives, emphasizing the 
potential integration of these compounds into therapeutic strategies that combine dietary, pharmacological, and 
lifestyle interventions to prevent or mitigate the multifaceted impacts of diabetic anemia on systemic and neural 
health.
