What is Creatine?

Welcome back to Super Achiever Club, where we explore the depths of health and fitness knowledge to empower you in your journey to greatness.


Chemical Composition and Biological Role of Creatine

  • Chemical Nature: Creatine is a nitrogenous organic acid, chemically known as methylguanido-acetic acid.
  • Biological Role: At its core, creatine plays a crucial role in energy production, especially in muscle cells. It aids in the formation of adenosine triphosphate (ATP), the cell’s energy currency.

Natural Sources of Creatine

  • Synthesis in the Body: Creatine is naturally synthesized in the liver, pancreas, and kidneys from amino acids like arginine, glycine, and methionine.
  • Dietary Sources: It’s also found in foods like red meat, fish, and poultry. However, the quantities in food can be limited, making supplementation an attractive option for many.

Historical Perspective

  • Discovery: Creatine was first identified in 1832 by French chemist Michel EugΓ¨ne Chevreul.
  • Initial Uses: Its early use was predominantly in the medical field before gaining popularity in sports and fitness for its performance-enhancing properties.

Creatine Supplementation


Types of Creatine Supplements

  • Varieties Available: The market offers various forms of creatine supplements, including creatine monohydrate, creatine ethyl ester, and micronized creatine. Each has unique characteristics and absorption rates.
  • Popular Forms: Creatine monohydrate is the most researched and widely used form. Best micronized creatine offers enhanced solubility.

Mechanism of Action

  • Cellular Level Workings: Creatine supplements increase the body’s store of phosphocreatine, aiding in the rapid regeneration of ATP during high-intensity activities.
  • Enhancing Performance: This increase in ATP availability translates to improved strength, endurance, and recovery during exercise.

Who Benefits Most from Creatine Supplementation?
