PROBLEMS FOUND WITH MULTIVITAMINS AND MULTIMINERALS BY CONSUMERLAB.COM
— Many Products Not Consistent with Label Claims and New Dietary Recommendations —
WHITE PLAINS, NY — February 14, 2001 — ConsumerLab.com announced today that only 14 of 27 products evaluated in its Multivitamin and Multimineral Product Review achieved full "CL Approved Quality" status. Problems found among products included less than the claimed amounts of ingredients, inadequate ability to disintegrate, and ingredient levels exceeding new Tolerable Upper Intake Levels (ULs) above which there can be a risk of toxicity.
Multivitamins/multiminerals are the most popular dietary supplements taken by Americans. Fifty-nine percent of consumers say they use a multivitamin, according to The Hartman Group, a natural products research firm. However, neither the U.S. government nor any other agency is responsible for routinely testing multis or other dietary supplements for their contents or quality. In addition, the latest Dietary Reference Intakes (DRIs), which include RDAs (Recommended Dietary Allowances) and ULs, issued by the Institute of Medicine of the National Academies have not yet been required by the U.S. Food and Drug Administration to appear in the "Supplement Facts" panel on products.
As part of its mission to independently evaluate products that affect health and nutrition, ConsumerLab.com purchased 27 multivitamin/multimineral products sold in the U.S., including general adult, prenatal, women's, senior's, and children's products. Of these, one-third (9 products) failed to meet the CL's criteria for Approved Quality, which included evaluation against the most recent DRIs. ConsumerLab.com's findings included the following:
- Two general adult products failed to disintegrate properly, suggesting that their contents would not be fully available for use in the body.
- One prenatal product had only 75% of its claimed amount of folic acid, which is important in reducing the risk of certain birth defects.
- One children's product was found to have more than 7,000 IUs (International Units) of vitamin A as retinol per tablet, which was more than 150% of its claimed amount and exceeds not only the RDAs but also the recently established ULs for children 1 to 13 years of age.
- Four general multis (two of which also failed on other criteria) claimed levels of 50 mg to 75 mg of niacin per suggested daily serving, exceeding the UL of 35 mg of niacin per day. One women's product also exceeded this UL. High levels of niacin can cause flushing of the skin as well as tingling, itching, burning and pain. The RDA for niacin is 14 mg for men and 12 mg for women.
- None of the products evaluated were found to have unacceptable levels of lead.
In addition, four of the eighteen products that passed testing were placed in a "Conditionally Approved" category, including three children's products. While they met their label claims, these children's products exceeded ULs for copper, niacin, vitamin A, and/or zinc set for younger children.
"Some of the problems we found were related to manufacturing issues, but more startling were the number of products designed to have ingredient levels that were out-of-line with what are now considered to be necessary or safe. For example, many children's products, despite the cute characters on their labels, did not seem appropriate for younger-aged children," noted Tod Cooperman, M.D., ConsumerLab.com's President. "The long-term daily use of multivitamins and multiminerals accentuates the need for consumers to read labels carefully and know what is appropriate for their themselves and their loved ones."
The general findings are available at www.consumerlab.com.
