Supplements and heart health.
Health supplements are promoted to help cardiovascular health. There has been a recent large analysis looking at the benefit of health supplements and cardiovascular health. The results seem to suggest that there is no benefit from these over the counter health supplements. Multivitamins do not seems to prevent cardiovascular events such as heart attacks. (USPSTF Annals of internal medicine Feb 2014).
Having a healthy diet and taking regular exercise are the key to reducing your risk of heart disease.
A further recent study has shown that having a vegetarian diet cuts your blood pressure. This is an association and the other aspects of being vegetarian such as lower body weight and cholesterol may play a part in the mechanism. Nevertheless being vegetarian does lower you blood pressure which is a major factor in development of heart disease (JAMA Internal Medicine Feb 24 2014).
So try just eating a healthy diet, get rid of the supplements and if you can cut out the amount of meat in your diet.
