High doses of vitamin C or E do not reduce Alzheimer's disease

Contrary to the results of previous scientific studies, older adults who took a non-prescription supplement of vitamin E or C did not show signs of reducing the risk of dementia or Alzheimer's. . This is the result of a new study published in the Journal of the American Geriatrics Society, which tracks results from patients who use vitamin C or E over a period of more than 5 years.

The study also found that a combination of two vitamins E and C, which is thought to enhance disease resistance, did not reduce the risk of developing dementia or Alzheimer's.

Shelly L. Gray, author of the study, said: 'There is little evidence to prove the benefits of taking vitamin supplements to prevent or delay Alzheimer's disease. In fact, other works have shown that high doses of vitamin E are even more dangerous for the elderly, such as a slightly increased risk of death. '

The exact cause of Alzheimer's remains a mystery. One theory is that high levels of free radicals in the brain may play an important role. Some vitamins such as vitamin E have the ability to neutralize free radicals and are thought to prevent cell damage in the body leading to the disease. Through the use of vitamin E above the body's normal need for activity, it is hoped that cell damage from oxidation can be prevented and lead to lower Alzheimer's disease.

Some older people use high doses of vitamin C or E in the hope of avoiding these diseases. The supplementary dose may be higher than the general dose and the content in multivitamin tablets.

From a point of view, vitamin E is still thought to be beneficial in fighting many diseases and so it is still widely used. However, there is growing evidence that vitamin E does not protect people from cardiovascular or cancer diseases that people think taking a lot of vitamin E will prevent it. Vitamin E is soluble in fat and not soluble in water, so the amount of excess vitamin is more difficult to be eliminated by the body.
