To take supplements of vitamins B6, B9 and B12 would not have a protective effect on the heart of the women to high risk to be reached of a cardiac disorder, according to Harvard researchers of the university.
The test clinique1 has been led by 5 442 women of 42 years and more, like considered at elevated risk to suffer from an infarction or stroke year. During more of seven years, the participants took a supplement of vitamin B6 daily, of folic acid (vitamin B9) and of vitamin B12 or a placebo. To the term of the test, 796 of the women had undergone a cardiovascular incident: 406 were part of the group that took the supplement and 390 belonged to the placebo group.
The supplement lowered the rates of homocysteine (an amino acid) of the topics, but did not have any impact on the number of attacks or cardiac deaths following a cardiac illness.
His / her / its results come to contradict the hypothesis according to which a rate raised blood of homocysteine would be a factor of risk for the cardiovascular unrests besides oz. Several studies demonstrated that, even though of raised doses of the vitamins B6, B9 and B12 fall made the rates of homocysteine of the participants, the risk of relapse or death accidentally cerebral vascular has not been reduced.
The majority of these tests having been led by men, the American researchers wanted to know if these vitamins could not contribute to warn the cardiovascular unrests at the women.
