Vitamin supplements are used to solve various health problems when vitamins and minerals entering the body with food are not enough. It has been proven that B vitamins help with a number of conditions, such as fatigue, visual impairment, disorders of the nervous system and even depression. But the shocking fact is that in fact these vitamins can lead to an increased risk of lung cancer, especially in men. What is this connection?
Given that approximately 46% of adults in the UK report supplementation of vitamins B6 and B12 as part of regular multivitamins in tablets, there may be concerns about the association of these vitamins with an increased risk of lung cancer.
According to the results of the study, men, especially men who smoke, have a higher risk of lung cancer if they additionally take large doses of vitamins B6 and B12.
In men taking these vitamin supplements, the risk of lung cancer was almost twice as high.
And the risk of lung cancer in men who smoke, as the study showed, is three to four times higher.
"In order to avoid lung cancer, especially in men, you should not additionally take large doses of vitamins B6 and B12, and these vitamins can harm male smokers," said Theodore Brasky, lead author of the study, researcher and associate professor at Ohio State University.
During the study, scientists interviewed more than 77 thousand people, asking them how often they take these B vitamins.
The study also took into account factors such as the dosage of vitamins taken and the usual diet over the previous 10 years.
Six years later, the researchers checked the health status of the study participants to identify signs of lung cancer.
After checking many indicators that are known to affect the risk of cancer, the researchers reported a 30 percent increase in the risk of lung cancer associated with taking vitamin B12 (taken as a separate vitamin), and a 40 percent increase in the risk of those who took vitamin B6.
It is striking that in men who have taken one or another vitamin in large doses for 10 years, the risk of developing lung cancer has almost doubled, and in men who smoke has increased even more.
"Men who took more than 55 micrograms of vitamin B12 per day had a 98% higher risk of lung cancer compared to men who did not take B vitamins," Brasky added.
"Men who smoked and consumed large amounts of B vitamins at the initial stage of the study were three to four times more likely to get lung cancer," he said.
"Vitamin B6 is usually sold in tablets of 100 mg (milligrams). And vitamin B12 is often sold in tablets from 500 mcg (micrograms) to 3000 mcg.
In contrast, most multivitamins contain 100% of the US recommended intake, which is less than 2 milligrams per day for vitamin B6 and 2.4 micrograms per day for vitamin B12.
In fact, people should ask themselves whether they need such an amount of a substance that is tens and hundreds of times higher than the recommended daily allowance."
According to a representative of the National Library of Health, the possible role of B vitamins in relation to cancer risk has been written about before.
"The results of two large—scale randomized controlled trials conducted in Norway and associated with additional intake of B vitamins indicate an increased risk of malignant tumors in people who received both vitamin B12 and B9 (folic acid), a result that was primarily based on lung cancer data," he added.
And according to the results of a cohort study conducted recently as part of the Vitamins and Lifestyle/VITAL program, men who took large amounts of vitamins B12 and B6 had a higher risk of lung cancer."
The World Cancer Research Foundation recommends that the key to cancer prevention is the desire to meet nutritional needs only with the help of a diet, and not just rely on supplements in the form of vitamins and minerals.
Foods rich in vitamins B6 and B12 include:
- Red meat — pork, beef, etc.
- Poultry meat — chicken, turkey, etc.
- Fish — tuna, salmon, etc.
