Insulin-like Growth Factor 1 (IGF-1)

Insulin-like Growth Factor 1 (IGF-1) is a protein in the body that plays a crucial role in growth and development, especially during childhood. It is produced mainly in the liver in response to growth hormone, which is released from the pituitary gland. IGF-1 helps cells grow and divide, supporting muscle and bone development. Beyond growth, it also plays roles in metabolism and has effects on various tissues throughout the body. Abnormal levels of IGF-1 can be linked to health issues, including growth disorders and certain diseases like diabetes and cancer.
