Antioxidant Vitamins for Heart Disease Prevention – Helpful or Harmful?

“Vitamin A is a substance that is suitable for you if you do not eat.”

Several scientific studies have shown a positive relationship between antioxidant vitamins and drawings of the heart. Antioxidants are ascorbic acid (vitamin C), alpha-tocopherol (vitamin E), folic acid, carotene (precursor of vitamin A), ubiquinone Q10 (coenzyme), bioflavonoids, and selenium. Most vitamin C and vitamin E

Vitamin C is water soluble vitamin. It promotes growth and tissue repair. Help for scar collagen is an important protein of the skin, tendons, ligaments and blood vessels. Vitamin C is also necessary for wound healing and repair and maintenance of cartilage, bones and teeth. Foods, the best source of vitamin C with green peppers, citrus fruits and juices, strawberries, tomatoes, broccoli, cabbage and other vegetables, sweet potatoes and seem to be white, and melons.


Vitamin E is soluble in fats and antioxidant properties. The hotel is located in vegetable oils and seeds, wheat germ, and small quantities of meat, fish, fruit and vegetables. Beta-carotene is an antioxidant, immune modulator, cancer and anti-pathogenic. and dietary carotenoids in fruits, vegetables, yellow-orange (such as carrots, sweet potatoes and pumpkin found) and green leafy vegetables (eg spinach and broccoli).

In 1985 Verlangieri and colleagues reported on the assumption that individuals consumption of fruit and vegetables Med lower mortality reported in coronary heart disease. Riemersma et al 1991 Lancet reported that patients had lower concentrations of vitamin E in the breast compared with the control group. Inverse relationship between the concentration of vitamin E and coronary heart disease mortality was also published in a report by Luoma and his colleagues in the north of Finland in 1995. National Public Health Institute and nutrition-based research cohort found an inverse relationship between higher intake of vitamin C (and accessories), and the risk of coronary heart disease over 10 years, 11 349 men and 25 women and 74 years in the United States. This information was published in Epidemiology in 1992. Protective effect of vitamin C in the heart in 1994 decreased, when the group an inverse relationship Knekt Vitamin C and coronary mortality found in a study of the epidemiology and announced their findings in the American Journal of Epidemiology.

Oxidation of harmful low-density lipoprotein (LDL) is an important factor for the development of atherosclerosis. This leads to plaque formation and development of rupture or blockage of the coronary arteries and heart attacks. can reduce LDL oxidation, plasma antioxidants and LDL particles and cell walls. Vitamins E and B-carotene is an important antioxidant fat-soluble vitamins. Vitamin C is water soluble antioxidant Champion. Reduction of LDL oxidation and progression of atherosclerosis is delayed, and perhaps regression. Antioxidants also improve the operation of the vessel wall and increases endothelial release of nitric oxide. Both effects favor of the market. Based on these tests, the medical community began to vitamin E at a dose of 400 IU daily recommended vitamin C dose of 500-1000 mg per day, in addition benefit from coronary heart disease.

However, further studies of the largest and best organized and strengthening benefits. Meta-analysis of 68 randomized trials with more than 230 000 participants were present 28th February 2007 Journal of the American Medical Association .The group, headed by Goran many Großauswertung, MD, University Hospital in Copenhagen, said that the combination of the data showed that seem to increase the additional intake of vitamins, beta carotene and vitamin E on the collaboration with the unexpected deaths. For vitamin C and selenium are not useful and not harmful, as they relate to heart disease. B-carotene has been found harmful to smokers. Although folic acid lowers homocysteine levels, not yet completed the investigation of CHD events. High homocysteine levels in blood serum with coronary heart disease. Ubiquinone, flavonoids, garlic and other supplements has not been tested sufficiently to reduce cardiovascular events, adequate strength, reliability and security in the long term.

“I do not need rejuvenation. The tablet of vitamin E, and I’m okay.” Actor William Shatner. Vitamins has many advantages. But what is the effect of vitamins and heart disease? It seems that the natural vitamin C and vitamin E are protective container. If the form of tablets, capsules or liquid will be so harmful. Then listen to the American Heart Association. Until scientific evidence available antioxidants, the best source of antioxidants is still well-balanced diet rich in fruits, vegetables and whole grains.
