Taking B vitamins, especially B6 and B12 puts you at serious risk of developing lung cancer. This was stated by a joint study conducted by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital, the Richard J. Solove Research Institute (OSUCCC – James), the Fred Hutchinson Cancer Research Center and the National Taiwan University. , the results of which were published in the Journal of Clinical Oncology. The link between vitamin B12 and B6 supplements and lung cancer
The study showed that there is a clear link between lung cancer and a continuous, high-dose intake of vitamins B6 and B12, which are typically used both to improve metabolism and to provide energy, as well as to compensate for deficiencies. due to the diet such as, for example, the vegan one or in some cases vegetarian. Data collected by the scientists revealed that the risk of lung cancer in those taking these supplements increases 2 to 4 times – a highly significant number. If vitamin B12 is deficient and you smoke it’s worse
Predictably, researchers led by Dr Theodore Brasky found that smoking increased this risk. Especially in males. In numbers, smokers who took more than 20 mg of vitamin B6 or 55 mcg of vitamin B12 per day for about ten years saw their risk of lung cancer increase compared to those who did not take the vitamins. Specifically, the risk increased by an additional 3 times in the case of vitamin B6 and by 4 times in the case of vitamin B12. Scientists note that this is the first prospective, observational study to examine the effects of long-term use of vitamin B6 / B12 supplements on lung cancer risk. The curious fact is that these supplements have been widely believed to reduce the risk of cancer.

For this study, Theodore Brasky, of the OSUCCC – James group, and colleagues analyzed data from more than 77,000 patients who were part of the VITamins And Lifestyle (VITAL) cohort study, a long-term prospective observational study designed to evaluate vitamins and other mineral supplements related to cancer risk. Participants were aged between 50 and 76 years. After enrolling in the study, participants provided the researchers with information about vitamin B usage over the past 10 years, including information on the dosage taken – which is considered a key detail, but often missing, yet necessary for better risk assessment and to search for associations. To draw their conclusions and obtain consistent data, Researchers evaluated numerous factors, including personal history of smoking, age, race, education, body size, alcohol consumption, personal history of cancer or chronic lung disease, family history of cancer of the lung and the use of anti-inflammatory drugs. «This – underlines Brasky – puts all these influencing factors on the same level, so we ended up with a less confused effect about a long-term over-supplementation of B6 and B12. Our data show that taking high doses of B6 and B12 over a very long period of time could contribute to the incidence rate of lung cancer in male smokers, which is certainly a concern worthy of further evaluation. ‘ body size, alcohol consumption, personal history of cancer or chronic lung disease, family history of lung cancer, and use of anti-inflammatory drugs. «This – underlines Brasky – puts all these influencing factors on the same level, so we ended up with a less confused effect about a long-term over-supplementation of B6 and B12.

The greatest danger, the authors of the study specify, comes from the overdose of these vitamins which, in general, and well above that recommended by dietary guidelines.
Remember that the recommended daily doses of vitamin B6, or biotin, are around 100-300 micrograms (mcg), while the recommended daily doses of vitamin B12 are around 2 micrograms a day. Unfortunately, to supplement these vitamins due to a diet often exceed the doses, and so you can expose yourself to other risks, as suggested by this study.
