Fish protein is used to support the muscles body system, and this use is supported by substantial scientific evidence. Fish is a high-quality source of complete protein, containing all essential amino acids necessary for muscle repair and growth. Multiple studies have demonstrated that dietary fish protein can stimulate muscle protein synthesis, similar to other animal proteins such as chicken or beef. For example, research published in peer-reviewed journals has shown that supplementation with fish protein hydrolysates can enhance muscle mass and function, particularly in older adults and athletes. Additionally, fish protein is generally low in saturated fat and contains beneficial nutrients such as omega-3 fatty acids, which have anti-inflammatory effects and may further promote muscle recovery after exercise.

Clinical trials and interventional studies have indicated that fish protein can be effective in preserving lean body mass during periods of calorie restriction and in supporting muscle health during aging (sarcopenia prevention). While fish oil (omega-3s) often receives more attention, the protein component itself is well-recognized in nutrition science for muscle support. Therefore, the use of fish protein for muscle health is justified by scientific validation, and its efficacy is supported by a robust body of clinical and nutritional research.
