Glucagon is a 29-amino acid polypeptide, which means it is definitively a protein. This vital hormone, secreted by the alpha cells of the pancreas, plays a crucial role in preventing blood sugar levels from dropping too low by signaling the liver to release glucose.

In reality, no vitamin is growth hormone; they are two fundamentally different substances with distinct roles in the body. A vitamin is an organic molecule essential for an organism's metabolism, whereas growth hormone (GH) is a peptide hormone produced by the pituitary gland. While vitamins cannot replace GH, certain ones can play supportive roles in the complex hormonal pathways that influence growth and repair.
