Consumerlab.com recently did an investigation into multivitamin/mineral supplements and found that over 30% of the products had inaccurate ingredient claims. Around two thirds of multivitamin products contained “significantly more or less ingredient than claimed,” or were contaminated with lead.
30% of the dietary supplements tested failed to meet label claims or quality standards, and over 40% of the products had ingredient levels that “may be too high for healthy individuals.”
75% of children’s multivitamins “exceeded tolerable intake levels” of vitamin A. The FDA currently recommends 1,300 IU for children ages 4 to 8 and an Upper Tolerable Intake Level (UL) of 3,000 IU. One product contained 5,000 IU of vitamin A. Safe niacin and zinc levels were also exceeded by many of these products.
Two thirds of men’s multivitamins were found to be “problematic,” with some products featuring extremely large amounts of lead and folic acid.
