Creatine: A Vital Compound for Energy, Strength, and Cognitive Function
Creatine is a naturally occurring compound found in muscle cells. It plays a critical role in energy production, particularly during short bursts of intense physical activity. Widely used as a dietary supplement, creatine is popular among athletes, bodybuilders, and fitness enthusiasts, and is also being studied for neurological and therapeutic benefits.
What is Creatine?
Creatine is a nitrogenous organic acid synthesized from the amino acids arginine, glycine, and methionine. About 95% of the body’s creatine is stored in skeletal muscles in the form of phosphocreatine, which acts as a rapid energy reserve for the regeneration of ATP (adenosine triphosphate), the primary energy currency of cells.
Forms of Creatine Supplements
Creatine Monohydrate – The most studied and widely used form; highly effective and affordable.
Creatine HCl (Hydrochloride) – More soluble; claimed to reduce bloating.
Buffered Creatine (Kre-Alkalyn) – Marketed for stability and absorption.
Creatine Ethyl Ester – Promoted for better absorption, though evidence is limited.
Micronized Creatine – Smaller particles for improved mixing and digestion.
