IGF-I is a natural protein required for normal growth and
health maintenance. IGF-I is structurally and chemically similar
to insulin and is normally present in almost all body tissues and
fluids including human breast milk and saliva.
Abnormally low levels of IGF-I are associated with several
disease conditions including dwarfism, malnutrition, osteoporosis
and infertility. It has been suggested that a decline in
IGF-I levels in human tissue causes many of the degenerative
changes associated with aging.
