Vitamins B6 and B12 with increase in Risk of Lung Cancer

Vitamins B6 and B12 with increase in Risk of Lung Cancer

Supplements are consumed on a regular basis by a large number of the world population. Most times, these supplements help in protecting the body against harmful substances that may be fighting against its wellbeing. However, it becomes even more worrisome when what you once thought was helping to protect against a condition like cancer becomes the primary cause of such illness.

This is what happened in the case of vitamin B. Before now; the vitamin was thought to fight against cancer, which was why most adults consumed it as part of their regular multivitamin. However, with the result of a study that shows that taking vitamin B6 and B12 will increase the chances or risk of lung cancer it calls for worry.


According to a study carried out at Ohio University, the risk of lung cancer was seen to be doubled to quadrupled by the consumption of vitamins B6 and B12. The study also showed that the risk is higher among men that smoke and it is a concern in men only as it was not reported to have an effect on women.

The researchers involved in the study said it was clear why a high dose of B vitamin supplements would increase the lung cancer of smoker rather than reducing it because the vitamins were supposed to strengthen the immune system and being the most important means of preventing lung cancer as well. They concluded that small unnoticed tumours might grow faster and cause the condition because the excess B vitamins might be feeding on them.

The primary cause of worry is among smokers because, during the study, it was found that men that stopped smoking for ten years back before the study were found to have no increase in the risk of lung cancer; instead the risk was the same with men that never smoked. This goes a long way in determining the fact that smoking is the primary determinant why vitamin B consumption in men increases the risk of lung cancer.

However, if you are a lover of multivitamins, you have nothing to worry about, because according to the researchers, the number of doses involved was well above those found in a daily multivitamin tablet. So you can take your vitamins at the usual dosage and still get the health benefits of the supplement so far you are not a smoker. There is no doubt that smoking cause’s lung cancer, it will be great if as a smoker, you give up smoking especially if you consume vitamin B as well. Staying alive is the ultimate goal, it’s better to do everything possible to maintain a healthy life.
