WHITE PLAINS, NEW YORK — JANUARY 19, 2007 — Fifty-two percent of multivitamins recently selected for testing by ConsumerLab.com were found to be contaminated with lead, unable properly break apart, or to contain significantly more or less ingredient than claimed. Results were reported today on the website www.consumerlab.com. Multivitamins are the most popular supplement in the U.S., with sales growing 8.4% to $4.16 billion in 2005 according to Nutrition Business Journal.
Among twenty-one products for adults and children that ConsumerLab.com independently selected and tested, only ten met their claims and other quality standards. Some of the most serious problems were:
Two pet multivitamins were also tested. Both contained their claimed ingredients, but one was contaminated with lead — 1.4 micrograms in a daily serving.
Several products provided, by design, doses of certain nutrients that exceed tolerable upper intake levels (ULs). Exceeding these levels may be appropriate for specific medical conditions but carry a risk of adverse effects, such as skin tingling from niacin, nausea and weakness from magnesium, and immune deficiency and anemia from zinc.
"Multivitamin and multimineral supplements are often touted as insurance against nutritional deficiencies, but problems with multivitamins appear to be common," said Tod Cooperman, M.D., President of ConsumerLab.com. He added, "Compounding any problem is the fact that a multivitamin may be taken for years." ConsumerLab.com advises consumers to factor in other sources of nutrients in their diet when determining their need for a supplement and to check its lists when selecting products."
The new report is available at www.consumerlab.com/results/multivit.asp. The report provides results for thirty-two supplements of which ConsumerLab.com selected twenty-three. Nine were tested at the request of their manufacturers/distributors through CL's Voluntary Certification Program and are included for having passed testing. Also listed are seven products similar to ones that passed but sold under different brand names. The report also provides the latest recommended daily intake levels and upper tolerable limits for nutrients to help consumers choose appropriate products.
Brands included the new report are AARP, Centrum, Dr. Fuhrman Pixie-Vites, Eniva, Flintstones, Floradix (Salus-Haus), Healthy Moments Vitamin Strips, Kirkland (Costco), Member's Mark (Sam's), Nature's Bounty, Nature's Plus, NOW, Nutrilite, One A Day (Bayer), One Source (Perrigo), Pet-Tabs, Pharmanex, Pregnancy Plus — Dr. Grunebaum, Puritan's Pride, Swanson, The Greatest Vitamin in the World, The Vitamin Shoppe, 21st Century Pet Nutrition, TwinLab (IdeaSphere), Vitamin World, WEIL, WinFuel, and Yummi Bears (Hero Nutritionals). Products include tablets, caplets, capsules, chewables, liquids, strips, gummies, and powders.
