Abstract

Abstract Background In recent years, public awareness of healthy diets has significantly increased, leading to a rise in the consumption of nutritional supplements. Among these, omega-3 fatty acids have become particularly popular. n − 3 polyunsaturated fatty acids (PUFAs) are widely distributed in marine and terrestrial environments. The primary sources of marine n − 3 fatty acid supplements are oily fish, such as anchovies, sardines and mackerel. Recently, they have drawn considerable attention for their potential therapeutic benefits in treating a range of illnesses, including cancer, neurological disorders, cardiovascular diseases, immunological and reproductive diseases, respectively. Main text This study explores the many activities of n − 3 PUFAs, highlighting their importance in cellular processes that include signaling pathways, cell membrane integrity and structural maintenance. These fatty acids significantly regulate important physiological functions including the neurological system, blood pressure control, hematopoiesis, glucose metabolism and inflammatory responses. The latter highlights the wide therapeutic range of n − 3 PUFAs is especially notable considering the implications for controlling inflammatory disorders. Furthermore, the chemistry and dietary sources of omega-3 fatty acids are clarified in this review, which also sheds light on the complex molecular pathways that support the therapeutic efficacy of these fats and their bioavailability. The most recent information on the FDA's approval of omega-3 oils for use in formulation development highlights the compounds' adaptability and potential influence on the development of novel medications. Conclusion A thorough analysis of omega-3 polyunsaturated fatty acids reveals both their remarkable therapeutic potential against a variety of diseases and their essential place in a normal diet. This study adds to the increasing amount of data that supports the use of n − 3 PUFAs in preventative and therapeutic approaches that are meant to improve human health and well-being by clarifying their mechanisms of action and emphasizing their applicability in formulation and development.
