Olive leaf extract and blood sugar
by Newsletter Editor
Those who are overweight can have blood sugar problems similar to those with type 2 diabetes, where the body does not produce enough insulin or does not use insulin to efficiently metabolize glucose. In this study, 46 overweight men took olive leaf extract (OLE) each day or a placebo, in two alternating 12-week phases. The daily amount of the main active ingredient in OLE was 51 mg of oleuropein, which was taken in pill form in a single dose.
While there were no improvements during the placebo phases, after each olive leaf phase, insulin sensitivity—the ability of cells to use insulin to metabolize glucose—improved 17 percent. Also, cells in the pancreas responsible for secreting insulin improved by 28 percent, a benefit that does not occur with the diabetes drug metformin, doctors said.
