Higher blood levels of vitamin B6 and the amino acid methionine appear to reduce lung cancer risk in smokers and nonsmokers alike.
Researchers evaluated levels of B6 and methionine in blood samples from participants in a study, which enrolled more than 519,000 participants from 10 European countries. After accounting for smoking, the researchers found that the higher the vitamin B6 and methionine, the lower the lung cancer risk.
WebMD reports:
“People in the highest group for vitamin B levels had a 56 percent reduced lung cancer risk, compared to those in the lowest group. Those with the highest methionine levels had a 48 percent reduced lung cancer risk, the researchers found.”
