Alpha-tocopherol decreases clumping of blood (platelet aggregation). This eases the passage of blood through capillaries and narrowed blood vessels. Betatocopherol has not been found to decrease platelet aggregation. Alpha-tocopherol has a regulatory effect on the tone of the muscles of the circulatory system. As the heart pumps, blood vessels must expand and contract.Alpha-tocopherol supplementation has been correlated with maintaining normal arterial wall flexibility.
Deficiency of Vitamin E
True vitamin E deficiency is rare in the United States and Canada. However, the consumption of less than optimal amounts of vitamin E is common. About onethird of adults were found to have blood levels of vitamin E at levels so low as to increase their risk of cardiovascular diseases. These low levels of vitamin E are
normally due to low dietary intakes. People who have difficulties absorbing fat are even more likely to have low levels of vitamin E. For example, people with cystic fibrosis may have low levels of vitamin E because of poor absorption of fats.
About one-third of adults were found to have blood levels of vitamin E at levels so low as to increase their risk of cardiovascular diseases.
With severe deficiency of vitamin E, red blood cell membranes can rupture. This may be because of oxidation of the cell membranes due to a lack of vitamin E. Severe, prolonged vitamin E deficiency can cause neurological problems including impaired vision and poor muscle coordination.
