Stroke Risk Not Cut By Folic Acid Supplements

Their findings are based on a review of clinical trials involving more than 39,000 participants.  Prior studies experts explain have linked low blood levels of a chemical lowered by folic acid to lower rates of stroke.  Stroke is one of the three major illnesses impacting older individuals according to the American Association for Critical Illness Insurance, the national educational organization.

Researchers at the UCLA Stroke Center in Los Angeles identified 13 well-designed clinical trials of folic acid and stroke. Participants in all the trials had been diagnosed with conditions such as kidney and heart disease, as well as stroke.

There were 784 strokes among 20,415 participants taking folic acid, compared to 791 strokes reported among 18,590 people who did not take the supplements.

The analysis which was published in the American Heart Association’s journal Stroke, settles the question about whether folic acid supplementation leads to a major reduction in stroke.  “The answer is ‘no,’” the lead researcher reports.

Still, the researchers suggest more research into folic acid and stroke, particularly for men and those in the earliest stages of heart disease. Data from both of those groups suggested there might be an effect, although researchers could not determine whether or not that was due to chance.

Those potential benefits appeared in trials carried out in countries whose food supplies were not fortified with folic acid. In the U.S., the benefits of folic acid supplementation may have already been achieved through food fortification. In an effort to reduce the birth defect spina bifida, the U.S. Food and Drug Administration required the addition of folic acid to all enriched cereal-grain foods starting in 1998.
