IGF-1 (or Insulin Like Growth Factor-1) is a protein that promotes tissue growth, organ health, and healthy blood sugar levels. Unfortunately, IGF-1 is a diminishing resource in an aging body. As we age and less Growth Hormone is released from the pituitary gland, there is a corresponding drop in IGF-1 levels, yet the bodies demand for IGF-1 does not decrease. As IGF-1 levels decline, the vitality and physical exuberance of youth recedes, further contributing to the process and experience of aging. There are many factors that contribute to the aging process. Of primary concern among these factors is the decline of the pituitary secretion of Growth Hormone and its conversion in the liver to the powerful growth promoting metabolite Insulin like Growth Factor (IGF-1).
