Insulin-like growth hormone/factor is described as what?

• A. A hormone that many body builders intake
• B. A digestive enzyme
• C. A vitamin
• D. A mineral

Answer: (A)

Insulin-like growth factor functions as a hormone in the body. It carries signals that promote growth and tissue repair, especially in muscle, by helping increase protein synthesis in response to growth hormone. In bodybuilding discussions, IGF is described as a hormone that many body builders intake because some athletes use it as a supplement to try to boost muscle growth. It is not a digestive enzyme, vitamin, or mineral—those categories refer to substances with different roles in digestion and metabolism.
