CoQ10 is one of the most widely sold health supplements on this planet. The people who make CoQ10 claim that this nutrient can cure every medical disorder under the sun and even improve the recession. As far as high blood pressure is concerned, the few studies that have been done reveal conflicting results. No double blind study has ever shown that CoQ10 can lower blood pressure. Some studies have been conducted for only 6- 8 weeks and involved 24-36 participants.
The current treatment of high blood pressure is a change in lifestyle and use of medications. If you want to live a long and healthy life, I suggest you dump this CoQ10 crap and take whatever medications your doctor ordered. High blood pressure is a silent disorder but it has real complications that are deadly.
