The B Vitamins – Supplements in High Doses May Cause Cancer

A new study published in the Journal of Clinical Oncology, claims that individuals using high doses of vitamin B, vitamin B-6, and vitamin B-12 supplements, may contract cancer. A total of seventy seven thousand one hundred eighteen individuals participated in this study. They were aged fifty to seventy six years.

On average these individuals had been using supplements for ten years. They were recruited for this study from year two thousand to year two thousand two. Interestingly enough, women using these same supplements were not susceptible to cancer.

However, men ingesting these vitamin B, vitamin B-6, vitamin B-12 supplements had a thirty to forty percent increase risk of obtaining cancer. None of them ingested multiple vitamins. Men whom had ingested these vitamins for ten years had a fifty percent risk of contracting cancer.

Individuals that were smoking tobacco products had an even greater risk of obtaining cancer. People from The Ohio State University College of Medicine, in Columbus, Ohio, Fred Hutchinson Cancer Research Center, in Seattle, Washington, and the College of Public Health and College of Medicine, National Taiwan University, in Taipei, Taiwan created this study. Vitamin B6 and B12 supplements are supposed to increase energy and your metabolism.

Dosages of B6 were just 20 milligrams per day. Dosages for B12 were fifty five micrograms. This study was published in the August twenty second two thousand seventeen edition of the Journal of Clinical Oncology.

Before this study, these supplements were thought to actually lower cancer risk. The following factors were used in this study:

* smoking history
* age
* race
* educational background
* body size
* alcoholic beverage consumption
* cancer or chronic lung disease history
* family lung cancer history
* anti-inflammatory drug usage

Theodore Brasky, Doctor of Philosphy, of the Ohio State University Comprehensive Cancer Center, was quoted as saying:

“This sets all of these other influencing factors as equal, so we are left with a less confounded effect of long-term B6 and B12 super-supplementation. Our data shows that taking high doses of B6 and B12 over a very long period of time could contribute to lung cancer incidence rates in male smokers. This is certainly a concern worthy of further evaluation.”
