“My cardiologist was so impressed with my results. By following Dr. Dunaief ’s advice, I’ve been able to stop all three of my blood pressure medications. My heart palpitations, which were limiting my activities, have dramatically reduced in frequency, my energy levels have increased and I have lost 15 pounds in two months.”

~ Nurse, age 62
