Review Highlights Marine-Derived Peptides' Neuroprotective Potential Against Neurological Disorders.
Background
Neurological illnesses are a significant global health burden, necessitating novel and safe therapeutic strategies beyond current limited options. Existing treatments often fall short in addressing the progressive nature and complex pathophysiology of conditions like neurodegenerative disorders. Blue foods, including marine fish, algae, and invertebrates, offer a rich source of bioactive proteins and peptides with inherent neuroprotective, anti-inflammatory, and antioxidant properties, making them a compelling area for exploring new therapeutic avenues. This review explores their potential to fill current treatment gaps.
Study Design
This study was designed as a narrative review, aiming to comprehensively summarize and critically analyze existing literature on marine-derived bioactive peptides and their neuroprotective potential. Researchers conducted extensive literature searches from January 2009 to March 2025 using PubMed and other biomedical databases. The methodology focused on synthesizing preclinical evidence to identify mechanisms of action and reported outcomes in animal models, providing a broad overview of the field's progress and future prospects.
Results
Preclinical evidence strongly suggests that marine-derived proteins and peptides exert neuroprotective effects through multiple mechanisms. These include the activation of antioxidant defense pathways, primarily via Nrf2-mediated signaling, and the modulation of NF-κB-associated neuroinflammatory responses. Furthermore, these compounds regulate serotonergic and dopaminergic neurotransmission and attenuate amyloid-β aggregation, a hallmark of certain neurodegenerative conditions.
Experimental studies in animal models reported significant improvements in cognitive performance, reductions in oxidative stress biomarkers, and decreased production of pro-inflammatory cytokines following administration of marine protein hydrolysates. These findings collectively highlight the multifaceted therapeutic potential of blue food biomolecules in mitigating neurological damage and dysfunction.

Why It Matters
Marine-derived peptides represent a promising frontier for novel neurological disorder therapeutics, offering a multi-targeted approach to neuroprotection, inflammation, and oxidative stress. For biohackers and clinicians, this research points towards future nutraceuticals or pharmaceutical interventions that could complement or surpass current treatments. While clinical translation faces hurdles like standardization, bioavailability, and regulatory complexities, ongoing advancements in nano-formulation, synthetic biology, and AI are poised to overcome these challenges, potentially leading to more stable, targeted, and scalable peptide therapies. This could eventually impact how we approach brain health and neurodegeneration through dietary or supplemental strategies.
