Vitamin E is a vital fat soluble vitamin that has antioxidant properties – it helps protect cells from the harmful effects of free radicals. The type of vitamin E that the human body is able to use is called alpha-tocopherol. Vitamin E is found in many foods, including whole grain products, eggs and dark leafy vegetables. The best way to ingest enough vitamin E is by providing a healthy, balanced diet that includes rich sources of this antioxidant.
Strengthens the immune system
Antioxidants help prevent cell damage caused by toxins resulting from normal metabolism. Vitamin E is a powerful antioxidant, as well as a fat-soluble vitamin. One of the ways in which vitamin E works is to strengthen the function of the immune system. Increased doses of vitamin E are particularly effective for men over 65 years of age. It has been found that regular vitamin E intake in this target group reduces the risk of developing upper respiratory tract infections.
Helps the heart
The Food and Nutrition Council of the U.S. Institute of Medicine states on the Website of the National Institutes of Health that vitamin E is widely known for its antioxidant properties, as well as its ability to multiply enzymes that contribute to the release of prostacyclin through arachidonic acid metabolism, thereby reducing platelet aggregation, which can lead to various cardiovascular diseases.
This requires further research, since so far only the alpha-tocopherol element of vitamin E has been studied in most cases, excluding the rest of its forms that are processed in the liver in the body. Some of these studies are ongoing; although there are indications that ingesting enough vitamin E can prevent the development of various diseases of the circulatory system.
Attacking free radicals
Although each of us is advised to move properly, the presence of harmful free radicals in the body actually increases precisely through physical activity. These are toxic metabolic byproducts that can accumulate in cells and damage them. Vitamin E is a powerful antioxidant that has the ability to "sweep up" these free radicals.
Vitamin E deficiency in animals is known to cause infertility. A clinical trial that given 100 to 200 IU (international units) of vitamin E per day to infertile men and women is being discussed at the University of Michigan Health Department. The study's lead doctor acknowledged that vitamin E reduces damage to sperm cells caused by the circulation of free radicals in the body. He also pointed to an increase in fertility after taking vitamin E supplements for one month on a daily basis. That study also points to a significant reduction in oxidative stress in sperm cells. Although these findings are positive, it was concluded that further research is needed to prove a conclusive link between increased fertility and vitamin E intake.
