2-(1-Methylguanidino)acetic acid compound with 2-hydroxypropane-1,2,3-tricarboxylic acid (1:1), commonly known as creatine citrate, is utilized as a dietary supplement and pharmaceutical agent. It supports increased energy production in muscle cells via ATP regeneration, enhancing athletic performance, muscle strength, and recovery from intense exercise. The citrate form improves solubility and stability in aqueous solutions, making it suitable for oral formulations. Additionally, it is researched for applications in treating metabolic disorders, muscular dystrophies, cardiovascular conditions, and cellular energy regulation issues.
