Vitamin E users show lower ALS risk
Daily Messenger (Pakistan)
People who regularly take vitamin E supplements over the years may have a decreased risk of developing the fatal neurological condition amyotrophic lateral sclerosis (ALS), a new study suggests.
ALS also known as
Up to 10 percent of ALS cases are an inherited form of the disease. In most cases, though, ALS occurs for no known reason.
...Some research has suggested that people with higher intakes of vitamin E have a lower risk of ALS. Those findings do not prove that vitamin E is the reason, but lab research has found that the vitamin which acts as a cellprotecting antioxidant can delay the onset of symptoms in mice genetically altered to develop an ALSlike condition.
Since ALS is so rare, researchers need to study large groups of people to see what lifestyle factors might be related to the disease.
So for the new study, researchers at
They found that there was a relationship between the length of vitamin E use and ALS.
.People who, at the start of their study, had been using vitamin E supplements regularly for at least five years were about onethird less likely than nonusers to develop ALS.
However, it's too soon to make any recommendations on vitamin E, Dr.
For one, the findings do not prove that vitamin E, itself, provided the benefit. The researchers did try to account for other lifestyle factors like people's weight, smoking habits, overall diet and exercise levels. And longer use of vitamin E supplements (from multivitamins or single supplements) was still linked to a lower ALS risk.
But there could still be other explanations for the finding. And promising findings on vitamin E have failed to pan out in the past.
Researchers once thought vitamin E supplements might prevent heart disease, based on studies showing lower rates among vitamin E users. But clinical trials where people were randomly assigned to take vitamin E or a placebo later showed no such benefit.
In addition, the current findings are based on small numbers. Of the 1 millionplus study participants, 805 were eventually diagnosed with ALS. And of those who had been using vitamin E for at least five years at the outset, just 18 developed ALS; there were 19 cases among people who had used the vitamin for fewer years.
