Many people in current days have been suffering from heart diseases. Blockage in the heart and the sudden heart attack has been a quite familiar health condition that several people go through nowadays.

As suggested by medical professionals, the clinical use of an antioxidant vitamin supplement can assist in preventing coronary artery disease (CHD) in people. 

Can Antioxidant Supplements Prevent Heart Disease?


Epidemiological studies show lower morbidity and mortality from coronary heart ailments in people consuming higher amounts of antioxidants in food or supplements that are used instead of food.

Various clinical studies show that supplementation that we consume instead of food seems to be beneficial in diminishing the frequency of coronary heart disease episodes.

Can Antioxidant Supplements Prevent Heart Disease?

As per multiple studies, antioxidant supplementation like vitamins C and E has advantages in preventing heart disease; but, the supplementation containing β-carotene can have harmful effects and thus is not advised.

According to some current evidence, coronary heart disease patients would likely be beneficial from consuming vitamin E at 400 IU on a per-day basis and vitamin C at 500 to 1000 mg regularly. Doctors prescribe vitamin supplements to people suffering from heart diseases to prevent heart disease in high-risk patients. Folate contains such a component that reduces towering homocysteine ​​levels, but there is no evidence yet for routine supplemental use. Other dietary supplements are currently being investigated by experts. 

There are various studies conducted on the antioxidant supplements impacting heart diseases. That study adumbrates the fact that there are multiple numbers of antioxidant vitamins available that are considered essential in reducing the risk of coronary artery ailments.

These antioxidants are antioxidants ascorbic acid (vitamin C), α-tocopherol (vitamin E), folic acid, β-carotene, ubiquinone (coenzyme Q10), bioflavonoids, selenium, etc., to name a few. This article will focus on the shreds of evidence of antioxidant supplements that prevent heart diseases.


B-Carotene has been one of the best sources of antioxidants which is often prescribed by doctors to avert heart diseases as much as possible. The best sources of B-carotene are orange juice, dark and leafy vegetable fruits, and vegetables and red-colored vegetables as well.

As suggested by the international and national dietary experts worldwide, one needs to consume one to five vegetables or fruits in a day to get proper antioxidants to fight heart diseases. 

Vitamin E

vitamin E can prevent peroxidation, a component of polyunsaturated fatty acid in membranes. The most active form of vitamin E is α-tocopherol. This is why vitamin E is considered an antioxidant. Doctors often prescribe vitamin E supplements and food as well to patients with heart diseases to limit heart ailments. Vegetable and seed oil contains vitamin E to a great extent. Consuming a certain amount of vitamin E in the diet or taking vitamin E supplements are recommended by doctors to keep heart diseases at bay. 

Vitamin C

Vitamin C is considered to be the principal antioxidant in plasma. Vitamin E is known as the water-soluble vitamin which traps free radicals in plasma and thus prohibits the chance of entering into LDL particles. Besides, Vitamin C revitalizes active vitamin E and enhances cholesterol excretion.

Vitamin C enhances endothelium-dependent vasodilation and has activeness in retarding monocyte adhesion. Vitamin c enriched food sources are strawberries, citrus fruits, melons, cabbage, tomatoes, green leafy vegetables (especially spinach).

Vitamin C-rich foods should be consumed raw, or you can take them raw to imbibe the antioxidants present in them. Every human being needs to consume at least 60 mg of vitamin c every day to retard heart disease or delay it. 

Contrary opinion

There is a contrary opinion that antioxidants can treat or prevent heart diseases. As per various studies, no clear evidence is found for taking dietary supplements. On the contrary, consuming certain vitamins in excess can be detrimental. As per multiple researchers, excess amounts of calcium and vitamin D are linked to an adverse impact that can invoke cardiovascular

diseases, says Miller. Although other researches are underway, there is little evidence that supplementing vitamin D in any amount will prohibit heart diseases, she adds. 

Another risk that is associated with taking the antioxidant supplements available over the counter is most of the antioxidant supplements are not adequate to prevent heart diseases and may be detrimental for the heart. Research has shown that herbal pills are frequently full of fillers like rice powder or even dangerous substances.

Some don’t even contain any of the herbs on the labels. “The manufacture of dietary supplements is not regulated by the FDA, nor does the industry have to demonstrate health benefits to use vague language like ‘good for heart health,’ but they cannot say, ‘it will lower blood pressure ‘” says Miller.

Bottom line

Studies are needed to examine the effects of a balanced combination of antioxidants at

levels achievable through diet. New paths are required to identify the precise role that antioxidants can play in the prevention of atherosclerosis. There are so many pieces of evidence that angiotensin-converting enzyme (ACE) inhibitors and type I angiotensin II receptor (AT1) blockers, in addition to their antihypertensive properties, may have great effects on oxidative stress.

Statins can not only improve lipid profiles but also reduce oxidative stress. Future antioxidant therapies should target the site of action more specifically, have no harmful effects on other signaling pathways, and target specific reactive oxygen (ROS) species or cell compartments.

Factors that are responsible for distressful and conflicting results from clinical and observational studies on the association between CVD and antioxidant vitamins may include differences in age, sex, age, weight, body, the dose of supplements vitamins in patients, and duration of treatment and eating habits. 

In the end, we can conclude that vitamins and supplements rich in antioxidants are not complete failures to prevent heart diseases. They can prevent mind symptoms. However, in severe cases, they might fail. But, if you want to take the circumspection in prime, you could go with antioxidant-rich foods and supplements. For supplements, you need to visit an expert so that you can be safe from its side effects.
