Delta-valerobetaine is primarily used in research and development within the field of biochemistry and nutrition. It is studied for its potential role as a biomarker in metabolic processes, particularly in relation to cardiovascular health and kidney function. Additionally, it has been explored for its possible applications in dietary supplements aimed at improving muscle performance and recovery, due to its involvement in the metabolism of amino acids and its potential to influence energy production. Its role in cellular osmoprotection and stress response mechanisms is also an area of interest in scientific studies.
