According to the study, published on Tuesday, men taking high doses of vitamins B6 and B12, had a higher risk of lung cancer.

The study found an increased risk of lung cancer in 30% -40% of men taking these vitamins from individual additives, not only from multivitamins or diet, according to researcher Theodore Braschi, an epidemiologist in the field of cancer prevention and control at the Medical College of Ohio. "I think these results indicate a synergy" between high doses of vitamin b, Smoking and risk of lung cancer among men, said Braschi.

The modern smokers, men taking the highest doses of vitamin B6, 3 cancer increased the risk of lung cancer within 6 years compared with those who did not take supplements. For vitamin B12 the risk is increased almost 4 times. Smaller amounts of these vitamins are involved in several vital processes in the body including DNA replication. But many supplements with a high dose, he said, expect to increase energy and giving the other not obvious benefits.

There were too few cases of lung cancer among non-smokers, to be included in a full analysis. Increased risk of lung cancer was observed among women or vitamin B9 also known as folate. Experts warn that the emphasis on B-vitamins may not be the most effective way to protect against lung cancer.
