FITMISS CREATINE provides 5g of clinically proven creatine monohydrate to enhance ATP production, promote muscular endurance, and fuel lean muscle and recovery.* First let us begin with how Creatine works in the body. The energy source for muscle is adenosine tri-phosphate (ATP). When your muscles are being worked, you deplete a phosphate bond and your energy source is reduced to adenosine di-phosphate (ADP). Creatine works to replenish that phosphate bond, restoring what was once ATP to re-energize and re-fuel your muscles to allow you to maintain your muscular endurance and increase your energy expenditure.* This formula contains the most studied and proven form of creatine, Creatine monohydrate. In addition to replenishing ATP, creatine monohydrate has an affinity for drawing excess water into the muscle cells, keeping your muscles hydrated, nourished, and full.
