What does creatine do?
Creatine is a naturally occurring compound in the body, specifically in human muscle cells. Intra-systemic synthesis is made possible by three amino acids: arginine, glycine in methionine. This process can occur in the kidneys, pancreas, liver, brain, and in men also in small amounts in the intestine. The total cumulative creatine content in the human body is close to 130 g. There are many positive effects on the market.
Is creatine harmful?
Supplementation with creatine-containing preparations may cause side effects. Among the most commonly reported symptoms are those from the digestive tract, such as diarrhea. However, numerous studies do not document health risks from even long-term supplementation.
Creatine and kidneys
One study published in the Journal of the International Society of Sports Nutrition showed no effect between long-term supplementation with creatine and renal functioning.
Creatine and male fertility
Significant statistical correlations between creatine intake and male fertility improvement have not been demonstrated.
Creatine before or after training
The best time to take creatine is during the training period. This is confirmed by studies conducted by Antonio and Ciccone, which showed a greater increase in muscle mass in people taking supplementation during training period than before the planned training unit.
