As I have repeatedly warned here and elsewhere, beware of the so-called “dietary supplements.” Almost uniformly they provide no benefits and may even be dangerous, indeed being promoted by the modern versions of “Snake Oil Salesmen.”
Supporting my contentions, the public is now allowed, in well-documented audiovisual format, to see the real truth about the untruths of “dietary supplements”. Frontline, The New York Times and the Canadian Broadcasting Corporation have co-produced a 55-minute video report that examines problems in the marketing and regulation of vitamins, herbals, and other “supplement” products. The report spotlights (a) contaminated products that have caused severe harm, (b) irresponsible promotion, (c) regulatory weaknesses, and (d) industry denialists: Frontline, Jan 19, 2016. I would strongly urge all individuals—both public and caregivers alike—to see it. It spells the issue out accurately and in no uncertain terms. Don’t miss it!
