The effect of very highly purified gastric inhibitory polypeptide (GIP) on insulin secretion in
man was tested in normal volunteers. Administration of physiological doses of GIP together
with glucose by IV infusion resulted in potentiation of the rise in IRI in the blood and
improvement in glucose tolerance. It is concluded that GIP is a potent insulinotropic
hormone and probably takes part in physiological potentiation of insulin secretion in
response to hyperglycemia during absorption of nutrients from the intestine.
