What Happens When You Put Two Great Blood Pressure Supplements Together?

Olive leaf extract and potassium have both individually proven their value for blood pressure. So, what happens when you put them together? Lots!

It’s crazy, but 22.6% of Canadian adults have high blood pressure. Crazier still is that nearly half of Americans over the age of 20 do. Worse, only 24% of Americans with high blood pressure have it under control.

This new double-blind study gave either an olive leaf extract-potassium combo or a placebo to 68 adults with mild to moderate high blood pressure. The supplement contained 1000mg of olive leaf extract standardized for at least 160 mg oleuropein and 300mg of potassium. The study lasted 12 weeks.

When blood pressure was monitored at home, diastolic blood pressure showed a trend to greater improvement than the placebo, but it did not reach significance. However, the more important systolic blood pressure dropped significantly more than the placebo. The drop in both systolic and diastolic blood pressure was clinically significant.

But that’s not all the natural supplement did. It significantly and clinically improved blood lipids, including a significant improvement in total cholesterol, LDL-cholesterol and triglycerides.

This study supports the use of a combination of olive leaf extract and potassium as a safe, effective natural aid for improving blood pressure and cholesterol, potentially helping to prevent cardiovascular disease.
