Five hundred milligrams of OLE when taken twice a day for two months continuously could significantly decrease systolic as well as diastolic blood pressure. Also, there are a number of side effects with Captopril such as loss of taste, cough, and dizziness. The above study was published in the European Journal of Nutrition.
OLE may act as an effective weapon in the fight against high blood sugar level or diabetes. A research conducted on the type 2 diabetes patients concluded that it can significantly drop the HbA1c levels – which is an indicator of how have the blood sugar levels been since past three months.
The OLE impacts the way the body interacts with sugar. It controls the levels of glucose in the body and keeps the blood sugar levels from spiking.
One can even reap anti-inflammatory benefits from OLE even if they aren’t diabetic. A small study conducted on middle-aged overweight individuals who were on the brink of developing metabolic syndrome, suggested that OLE indeed can increase the insulin sensitivity by fifteen more as compared to placebo. The beta cells, which are responsible for secreting insulin, showed increase by twenty eight percent.

These antioxidants may also kill the tumor cells without affecting the healthy ones. Oleuropein, the substance present in OLE can prevent the multiplication of cancer cells in addition to curbing the growth of new blood vessels to feed on the cancer cells. However, more research is required on the same. It can be taken alongside the chemotherapy under the guidance of the oncologist.
