Fish protein is scientifically recognized as a high-quality, complete protein source, containing all essential amino acids necessary for muscle protein synthesis. Several studies have demonstrated that dietary protein, including fish protein, supports the maintenance and improvement of muscle mass and muscle tone, particularly in populations at risk of muscle loss, such as the elderly or those with sarcopenia. Fish protein is rich in branched-chain amino acids (BCAAs) like leucine, which are directly involved in stimulating muscle protein synthesis. Additionally, fish proteins are highly digestible, making them effective for supporting muscle repair and maintenance. Some research also suggests that bioactive peptides found in fish protein may have additional health benefits, such as anti-inflammatory effects, which could indirectly support muscle health. However, while fish protein is an excellent source of nutrition for muscle health, there is limited direct clinical research specifically evaluating its effects on "muscle tone" as opposed to general muscle mass or strength. Most evidence extrapolates from broader studies on dietary protein and muscle health. Thus, while scientific evidence supports the use of fish protein in maintaining and supporting healthy muscle, the direct connection to improving “muscle tone” is less extensively studied but is biologically plausible based on current understanding of protein metabolism.
