CoQ10 is a naturally occurring enzyme. It contains antioxidants that are good for maintaining cardiac health. CoQ10 has been shown to decrease blood pressure and reduces the thickening of the heart muscle (hypertrophy). There are no known side effects of CoQ10 since it naturally occurs in the body. According to the Mayo Clinic, for the treatment of hypertension, take 60-360 milligrams daily for 8-12 weeks.
A study published in the Journal of Bioscience, Biotechnology and Biochemistry looked at the effect that vinegar has on blood pressure if it is introduced to your diet. The results of the research showed that consumption of acetic acid (which is found in apple cider vinegar) caused a significant reduction in hypertension (high blood pressure). The research found that the acetic acid reduced blood pressure by lowering the renin activity. Renin is an enzyme which helps regulate blood pressure.

There are many good options when it comes to such medication. Examples are ACE (angiotensin-converting-enzyme) inhibitors or AII-blockers (angiotensin II receptor blockers) such as Enalapril or Losartan. If this kind of medication doesn’t give the desired effect, you might have to add other medication such as so-called calcium antagonists (e.g. Felodipin) or a mild diuretic (can be found as a combined pill with Enalapril and Losartan).
