Why Creatine Capsules?
Creatine is naturally produced in the human body from amino acids L-arginine, glycine, and L-methionine primarily in the kidney and liver and transported in the blood to help supply energy to all cells in the body.
Creatine is metabolised into phosphocreatine, an important storage form used by the brain, heart, and skeletal muscles. In normal healthy individuals, muscle creatine is replenished at a rate of approximately two grams a day. Oral ingestion of creatine has been shown to suppress the body's natural production, an effect that has been shown to be reversed upon ceasing supplementation.
Creatine exerts various effects upon entering the muscle. It is these effects that elicit improvements in exercise performance and may be responsible for the improvements of muscle function and energy metabolism seen under certain conditions.
Several mechanisms have been proposed to explain the increased exercise performance seen after creatine intake:
- Optimizing energy metabolism by maintaining higher levels of the body's energy compound adenosine triphosphate or increasing myofibrils mRNA content and protein synthesis, and reducing amino acid oxidation and protein break-down.
- Increasing satellite cell and myonuclei number and activity in human skeletal muscle.
- Preventing tissue damage by stabilising cellular membranes and maintaining reserves of ATP.
