Creatine is a natural substance that is found in the muscles of all vertebrates. It is a key component of the body's energy production system and plays a vital role in muscle contraction and recovery. Creatine supplementation has been shown to improve performance in a wide range of activities, including sprinting, weightlifting, and endurance sports.
Creatine is synthesized in the liver and kidneys from three amino acids: glycine, arginine, and methionine. It is then transported to the muscles, where it is stored as phosphocreatine. When the muscles need energy, phosphocreatine is broken down to release creatine and phosphate. The phosphate is then used to generate adenosine triphosphate (ATP), the body's main energy currency.
Creatine supplementation has been shown to increase the amount of phosphocreatine stored in the muscles, which can lead to improved performance in activities that require short, high-intensity bursts of energy, such as sprinting and weightlifting. Creatine can also help to improve recovery from exercise by reducing muscle damage and soreness.

Synthesized in liver and kidneys.
Creatine is synthesized in the liver and kidneys from three amino acids: glycine, arginine, and methionine. The process of creatine synthesis is complex and requires several steps.
Step 1: Glycine and Arginine Combine to Form Guanidinoacetate
The first step in creatine synthesis is the combination of glycine and arginine to form guanidinoacetate (GAA). This reaction is catalyzed by the enzyme glycine amidinotransferase (GAT).
Step 2: GAA and Methionine Combine to Form Creatine
In the second step, GAA reacts with methionine to form creatine. This reaction is catalyzed by the enzyme creatine synthase (CS). CS is found in the mitochondria of liver and kidney cells.
Step 3: Creatine is Transported to the Muscles
Once creatine is synthesized, it is transported to the muscles via the bloodstream. Creatine can also be obtained from dietary sources, such as meat and fish. However, creatine supplementation is often used to increase muscle creatine stores beyond what can be obtained from diet alone.
Creatine is an essential nutrient for muscle function. By synthesizing creatine in the liver and kidneys, the body is able to maintain adequate creatine levels in the muscles to support muscle contraction and energy production.
Stored as phosphocreatine in muscles.
Once creatine is transported to the muscles, it is converted into phosphocreatine (PCr) by the enzyme creatine kinase (CK). PCr is then stored in the muscles, where it serves as a reservoir of energy for muscle contraction.
- PCr: A High-Energy Molecule
PCr is a high-energy molecule that can be broken down quickly to release creatine and phosphate. The phosphate is then used to generate ATP, the body's main energy currency.
- Location of PCr in Muscles
