B-vitamin supplements should not be recommended for prevention of heart disease because they do not reduce the risk of developing or dying from the disease
B-vitamin supplements should not be recommended for prevention of heart disease because they do not reduce the risk of developing or dying from the disease, according to a Cochrane Systematic Review.
"There is no evidence to support the use of B-vitamins as supplements for reducing the risk of heart attack, stroke or death associated with cardiovascular disease," says Arturo MartÃ-Carvajal, of the Iberoamerican Cochrane Network in Valencia, Venezuela."And it is important to point out that although we may have not found a positive effect, these kinds of studies are vitally important for determining the factors that influence the risk of developing and dying from this disease, which is the number one cause of death in the world today," adds the lead researcher.
According to background information in the review, certain B-vitamins-specifically B12, B9 (folic acid) and B6-influence levels of an amino acid in the blood called homocysteine.
The report further states that high levels of this molecule are associated with an increased risk of heart disease.
The Cochrane researchers say that B-vitamin supplements have been considered to be helpful in regulating levels of homocysteine, and, thereby, in reducing the risk of cardiovascular disease and death.
However, they insist, there is no scientific basis for this claim.

Together, the data showed that B-vitamin supplements, whether compared with placebos or standard care, had no effect on the incidence of heart attack, stroke or death associated with heart disease.
