• Fish-derived protein has emerged as a promising alternative dietary supplement due to its high biological value, balanced profile of essential amino acids, and the presence of bioactive peptides with potential health benefits. This review aims to compile and discuss recent scientific evidence regarding the use of proteins extracted from fish, focusing on the benefits associated with this protein source. Several studies have demonstrated that the intake of fish proteins can lead to positive effects such as increased satiety, improved body composition, and support for muscle protein synthesis, which is particularly relevant for elderly populations, individuals with sarcopenia, and physically active individuals. Furthermore, these proteins play a role in appetite regulation, energy metabolism, and the maintenance of lean body mass. Despite the promising outcomes, further clinical studies are needed to assess their efficacy, safety, and applicability across different physiological and population contexts. Thus, fish protein stands out as a functionally and nutritionally valuable source, with promising applications in human nutrition and potential for use in the development of novel and sustainable food products.
