L-Homocitrulline is primarily studied for its role in metabolic processes and its potential therapeutic applications. It is often explored in the context of urea cycle disorders, where its presence can serve as a biomarker for certain metabolic dysfunctions. Research has also investigated its use in managing conditions related to nitric oxide metabolism, as it may influence vascular health and blood flow. Additionally, L-Homocitrulline is being examined for its potential antioxidant properties, which could contribute to reducing oxidative stress in various physiological conditions. Its applications extend to nutritional supplements aimed at supporting cardiovascular health and improving exercise performance by enhancing nitric oxide production.
