Heart disease is the number 1 cause of death in the world (27Trusted Source).
Researchers have studied it for many decades and learned a lot about why it happens.
Unsurprisingly, heart disease is incredibly complicated and various things contribute to it.
Curcumin may help reverse many steps in the heart disease process (28Trusted Source).
Perhaps the main benefit of curcumin when it comes to heart disease is improving the function of the endothelium, which is the lining of your blood vessels.
It’s well known that endothelial dysfunction is a major driver of heart disease and involves an inability of your endothelium to regulate blood pressure, blood clotting and various other factors (29Trusted Source).
Several studies suggest that curcumin leads to improvements in endothelial function. One study found that it’s as effective as exercise while another shows that it works as well as the drug Atorvastatin (30Trusted Source, 31Trusted Source).
In addition, curcumin reduces inflammation and oxidation (as discussed above), which play a role in heart disease as well.
One study randomly assigned 121 people, who were undergoing coronary artery bypass surgery, either a placebo or 4 grams of curcumin per day, a few days before and after the surgery.
The curcumin group had a 65% decreased risk of experiencing a heart attack in the hospital (32Trusted Source).
