Creatine can improve health and athletic performance in various ways

In high-intensity exercise, its main function is to increase the reserve of phosphocreatine in muscles

The additional storage can then be used to generate more ATP, which is a key energy source for weightlifting and high-intensity exercise

Creatine can also help you gain muscle through the following ways:

Increasing workload: Achieving more total workload or training volume in a single training session is a key factor for long-term muscle growth
Improved cell signaling: can increase satellite cell signaling, which helps with muscle repair and new muscle growth
Improving synthetic metabolic hormones: Studies have shown that taking creatine increases hormone levels, such as IGF-1
Increasing cell hydration: Increasing the water content inside muscle cells can lead to a cell filling effect, which may play a role in muscle growth
Reduce protein breakdown: It may increase total muscle mass by reducing muscle breakdown
Reduce levels of muscle growth inhibitor: Elevated levels of protein muscle growth inhibitor can slow down or completely inhibit the growth of new muscles. Supplementing creatine can lower these levels and increase growth potential
Creatine supplements can also increase the storage of phosphocreatine in the brain, which may improve brain health and prevent neurological disorders
