American doctors from Ohio State University have identified a possible link between high intake of vitamins B6 and B12 and an increased risk of developing lung cancer, particularly among male smokers. The study, which analyzed health data from 77,000 people, showed that men taking more than 55 micrograms of B12 daily had a 98% higher risk of lung cancer, while excess vitamin B6 was associated with a 40% increased risk. Smokers who consumed supplements were at particular risk, with the risk increasing three to four times. Scientists suggest that high doses of B vitamins may activate metabolic processes that promote cell growth and affect DNA methylation. To reduce risk, doctors advise following recommended dosages, limiting supplement intake when eating a balanced diet, consulting a specialist, and quitting smoking. The article emphasizes the need for a cautious approach to vitamin supplements, especially in the presence of risk factors.
