Men who smoke should not use high dose vitamin B

For a long time, vitamins B6 and B12 have been advertised by pharmaceutical companies as supplements to boost energy, improve metabolism, and are even thought to reduce the risk of cancer.

However, a recent study has shown the opposite result if using these supplements with too high doses.

The study, published in Clinical Oncology on August 22, shows that high doses of vitamin B6 and B12 make men, especially smokers , significantly increase the risk of lung cancer .

Foods that contain vitamin b12.

The discovery comes after the Ohio State University Center for Cancer Research team monitored more than 77,000 patients in the United States for more than a decade.

According to the study, men who take supplements, especially vitamins B6 and B12 at regular high doses for 10 years, nearly double the risk of lung cancer. Even men who smoke and use these supplements are 3-4 times more likely to develop lung cancer.

However, women who take vitamin B6 and B12 supplements for a long time do not increase their risk. Since then, the study recommends that men should only drink about 1.5 milligrams of B6 daily and less than 2.5 milligrams of B12.

In addition, the study also suggested that it is not necessary to take high-dose vitamin B supplements, instead can eat foods rich in vitamin B such as cereals, meats, fruits and legumes.
