LONG TERM HIGH DOSE SUPPLEMENT WITH VITAMINS B6 AND B12 INCREASE LUNG CANCER IN MEN SUGGESTS A NEW RESEARCH
New research suggests long-term, high-dose supplementation with vitamins B6 and B12—long touted by the vitamin industry for increasing energy and improving metabolism—is associated with a two- to four-fold increased lung cancer risk in men relative to non-users.
Epidemiologists from The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James), Fred Hutchinson Cancer Research Center and National Taiwan University report their findings in the Aug. 22, 2017 issue of the Journal of Clinical Oncology.
This is the first prospective, observational study to look at the effects of long-term high-dose B6/B12 supplement use and lung cancer risk. These supplements have been broadly thought to reduce cancer risk.
For this study, Theodore Brasky, PhD, of the OSUCCC – James, and colleagues analyzed data from more than 77,000 patients participants in the VITamins And Lifestyle (VITAL) cohort study, a long-term prospective observational study designed to evaluate vitamin and other mineral supplements in relation to cancer risk. All participants were aged between 50 and 76 were recruited in the state of Washington between the years 2000 and 2002. Upon enrolling in the study, participants reported information to researchers about B-vitamin usage over the past 10 years. This included dosage information—a critical but often missing detail needed for strong risk assessment and association research.
