You can get twice the result with half the effort, but it is very important to use it correctly. Supplementing pure creatine can increase muscle strength and speed. Creatine is an amino acid that exists in muscle in the form of creatine and creatine phosphate. The human body mainly uses ATP to provide energy during high-intensity exercise, but the ATP reserve in the human body is very small and needs to be synthesized continuously, and creatine phosphate can promote the synthesis of ATP. However, in high-intensity exercise, the reserve creatine phosphate in muscle is exhausted after about 6-8 seconds. Creatine supplementation can increase the content of creatine in skeletal muscle, make more creatine combine with phosphoric acid, and increase the concentration of creatine phosphate in muscle, thus improving the rapid contraction ability, speed endurance and explosive force of muscle. Another important function of creatine supplementation is to neutralize the acidity in the body, which is very important for delaying fatigue.
