Vitamin E and heart diseases prevention
If you are not sure whether Vitamin E is preventing heart diseases, read on.
Perhaps like a lot of people you are popping Vitamin E capsules on your own or a doctor’s advice and suddenly you are confronted with confusing advice. What would you do?
There are no clear cut answers as findings have been very contradictory regarding the benefit of Vitamin E in cardiovascular health.
Vitamin E and heart disease prevention: proof
A study by the University of Cambridge in 1996 found that those taking Vitamin E had a 77 percent reduced risk of non-fatal heart attacks.
Observational and in vitro studies have found that Vitamin E inhibits oxidation of low-density lipoprotein (LDL) cholesterol, which may have a preventive effect on atherosclerosis. It might also help prevent the formation of blood clots that could lead to a heart attack or venous thromboembolism.
Vitamin E and heart diseases: contradictory
Another study, the Heart Outcomes Prevention Evaluation (HOPE) study found that Vitamin E offered no significant protection from heart attacks, strokes, angina attacks or death. On the contrary participants taking vitamin E were at 13 percent greater risk and 21 percent more likely to be hospitalized for heart failure.
Some other studies reported similar findings, though the numbers varied. And yet another study of men below 50 found that use of vitamin E was associated with a significantly increased risk of hemorrhagic stroke.
Researchers at the Cleveland Clinic did a meta analysis of various research findings in a bid to come to a conclusion. This was published in the British medical publication, Lancet. It said that there was no significant benefit seen in the routine use of Vitamin E on cardiovascular health.
Should you stop taking it?
One thing to keep in mind before giving up Vitamin E completely is that almost all the studies were done on middle aged or older people who already had heart disease or had the risk factors for heart disease.
You also need to remember that vitamin E are effective to prevent and treat many other health conditions. So it is important to have recommended doses of vitamin E in your diet.
Then there is the source of Vitamin E which may be important. Most synthetic forms known as a (dl)alpha-tocopherol
two time less active than natural form (d)alpha-tocopherol. There are more other forms and they have different activities and benefits.
You also should keep in mind that in order to be absorbed, Vitamin E needs the presence of fat and bile or needs to be in a micellized form.
The American Heart Association diet holds that it is advisable to eat a
balanced heart healthy diet which is rich in natural anti-oxidants. However, further research on people who are free of diagnosed cardiovascular disease is necessary to come to a conclusion on the importance of Vitamin E for lowering the risk of developing major cardiovascular diseases.
