How Does Creatine Work?
Creatine is a molecule that our body produces, mainly by the liver. It’s also found in foods like beef, chicken, and fish. It fuels ATP, the energy machines in muscle with three strongly bound phosphates.
When a phosphate breaks loose, energy is released. This is where creatine steps in to replenish the phosphates to keep ATP running efficiently. It stores high-energy phosphate groups in the form of phosphocreatine.
Phosphocreatine releases energy to aid in cellular function. This causes strength increases after using creatine, and can also benefit your brain, bones, muscles, and liver.
Creatine also attracts water, so as your muscles absorb and store creatine, it brings additional water with it. This process super-saturates the muscle tissue with water and creatine, thus enlarging the actual muscle tissue.
