Stevia Leaf Powder

Diabetes. Some early research suggests that taking 1000 mg daily of stevia leaf extract might reduce blood sugar levels after eating by a small amount in people with type 2 diabetes. But other research shows that taking 250 mg of stevioside, a chemical found in stevia, three times daily does not decrease blood sugar after three months of treatment.
High blood pressure. How stevia might affect blood pressure is unclear. Some research suggests that taking 750-1500 mg of stevioside, a chemical compound in stevia, daily reduces systolic blood pressure (the upper number in a blood pressure reading) by 10-14 mmHg and diastolic blood pressure (the lower number) by 6-14 mmHg. However, other research suggests that taking stevioside does not reduce blood pressure.
