Creatine monohydrate, also referred to as N-methylguanidine acetic acid, myosin, metguanidine acetic acid, and myosinine, serves as a pharmaceutical raw material and an additive in health products. It functions to inhibit the production of muscle fatigue factors, thereby alleviating fatigue and tension, restoring physical energy, accelerating human protein synthesis, enhancing muscle solidity and elasticity, lowering cholesterol, blood lipid, and blood sugar levels, improving muscle atrophy in middle-aged and elderly individuals, and delaying aging. As the most extensively researched and widely applied creatine product with the longest history of use, creatine monohydrate finds broad application as a food additive, cosmetic surfactant, feed additive, beverage additive, medicinal raw material, and health product additive. Additionally, it can be directly formulated into capsules or tablets for oral administration and is commonly utilized as a nutritional fortifier.
