Fish protein, and more specifically the nutrients derived from fish such as omega-3 fatty acids, have been studied for their role in supporting nerve health and potentially aiding in nerve damage recovery. Scientific evidence suggests that omega-3 fatty acids—particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which are abundant in fish—play an important role in maintaining neuronal membrane integrity, reducing inflammation, and supporting neuroregeneration. Experimental studies in animal models have shown that fish oil supplementation can promote nerve regeneration and functional recovery following peripheral nerve injuries. Furthermore, omega-3s have demonstrated neuroprotective effects in models of neurodegenerative diseases and neuropathies.

However, the majority of this evidence comes from preclinical and animal studies, with human clinical trials still limited and often focusing on broad neurological health rather than direct therapeutic effects on nerve damage. Fish protein also provides essential amino acids, which are necessary for tissue repair and regeneration, but the specific effects of fish protein (as opposed to fish oil/omega-3s) on nerve damage are less well studied. Therefore, while there is a scientific basis for recommending fish-derived nutrients for nerve health, the strength of evidence for fish protein specifically in the treatment of nerve damage is moderate and not yet definitive. More rigorous human studies are needed to clarify optimal dosing, mechanisms, and clinical benefits.
