IGF-1 stands for insulin-like growth factor. Like the name declares, it’s like "the brother" of insulin. Both messenger substances play an important role in various development processes of the body.
Insulin determines a tight regulation of the blood sugar level. It ensures that there is always enough energy available for the body to work with.
However, the growth factor IGF-1ensures the growth and development of all types of body cells and organs. These are, for example, egg-cells, muscle cells, blood vessels, etc. In this way, insulin and IGF-1 are compatible.
