This is especially true for smokers. When a man smokes and uses more than 20 mg of vitamin B6 for over 10 years or more than 55 mg of vitamin B12 per day, the likelihood of
lung cancer increases considerably. Vitamin B6 is a triple, with vitamin B12 evenquadrupled. This is shown by an investigation of more than 77,000 Americans in Washington State. All participants were between 50 and 76 years old. For ten years, the subjects gave information about drug use.
The researchers took into account all kinds of factors, such as how long a person smokes, age, race, education, body weight, alcohol consumption and medical history. "We continued on with a clear connection between vitamin B6 and B12 super supplements and the likelihood of lung cancer in smokers," concludes researcher Theodore Brasky.
Whoever swallows multi vitamins daily does not have to be afraid. Most multivitamins contain only one or two milligrams of B6 or B12 per dragee. The recommended daily amount of vitamin B12 is about 2.8 micrograms. Over 55 milligrams (55,000 micrograms!) Per day are therefore a considerable overdose of B12. The recommended daily amount of vitamin B6 is determined for adult males and females at 1.5 milligrams. That's also much less than 20 mg.
"The doses of 55 mg B12 and 20 mg B6 can only be achieved when someone swallows many supplements," Brasky continues.
Thus, pills are sold with 5 mg B6 or B12 per pill, which is much more than the recommended amount.
In men who do not smoke, the likelihood of lung cancer is twice as high in heavy vitamin B6 and B12 use. Women are lucky because they do not have an increased chance of lung cancer.
