👉 Creatinin is a type of protein found in muscle cells. It plays a crucial role in energy production and recovery after exercise, as well as in maintaining muscle function during sleep. In the context of nutrition and health, creatinin can be beneficial if consumed in sufficient amounts to support muscle function and growth. However, it's also important to consume this type of protein in moderation to avoid potential negative side effects such as fatigue or digestive issues due to its high protein content.
