Daniel Fabricant, PhD, and vice president of scientific and regulatory affairs for the Natural Products Association is featured in a Nutra Ingredients post responding to a recent study released in the Journal of the American Medical Association. The study in question concluded that taking vitamin B did nothing to reduce the risk of cardiovascular events or death caused by coronary heart disease. “...the study’s exclusion criteria leave much to be desired,” Dr. Fabricant said. From the article:
“For example, over 78 percent of the subjects were concomitantly taking beta blockers, and over 88 percent were taking statins amongst other medical interventions and treatments,” he [Fabricant] said. “We have no way of knowing from reading the study whether these interventions were continued through the lifecycle of the study, which could significantly influence the outcomes. The researchers mention adherence to the 'study medication' (the B-vitamins) but not to other treatments; additionally the authors did not control food intake for folic acid, B-6 or B-12.”
He said the fact functional foods were “not required” in Norway did not mean they were not widely consumed and that this factor, along with potentially inaccurate self-reporting of supplements use, further wavered the results.
