Marine protein, primarily sourced from fish, shellfish, and other marine organisms, is supported by scientific evidence for its role in supporting muscle tone. Marine protein is a rich source of essential amino acids, particularly leucine, which is crucial for muscle protein synthesis. Multiple clinical studies have shown that dietary protein intake, including marine sources, can help promote muscle mass and function, especially in populations at risk of muscle loss such as the elderly or those recovering from injury (Kim et al., 2019).

Compared to some plant proteins, marine protein is highly bioavailable and often contains additional nutrients like omega-3 fatty acids, which have been shown to further support muscle health by reducing inflammation and potentially enhancing muscle protein synthesis (Frontiers in Nutrition, 2022). However, while the general role of protein in muscle health is well-established, there is less direct evidence specifically comparing marine protein to other protein sources for muscle tone in healthy individuals. Most studies focus on overall protein adequacy rather than the unique properties of marine protein itself.

In summary, there is moderate scientific support for the use of marine protein in supporting or treating lack of muscle tone, primarily due to its high-quality amino acid profile and additional nutrients, although more targeted research on its specific advantages over other protein sources would be valuable.
