Supplement Quality and Concerns
Multivitamins are the most popular dietary supplements in the United States, accounting for $4.8 billion in sales in 2009. However, there is no standard formula for multivitamins, and no U.S. agency that routinely tests multivitamins, so formulations and quality can vary widely. Additionally, vitamin and mineral needs and tolerances differ based on factors such as age, gender, health conditions and pregnancy, so there is no one formula that is appropriate for everyone.
Considerations for multivitamin quality include verifying that the supplement contains the amounts of specific vitamin ingredients claimed on the label, tablet disintegration (which can affect absorption) and the potential for lead contamination. ConsumerLab.com has reported the quality of multivitamin supplements to vary widely, and that price is not predictive of quality.

Famous quotes containing the words supplement, quality and/or concerns:
“Art is not merely an imitation of the reality of nature, but in truth a metaphysical supplement to the reality of nature, placed alongside thereof for its conquest.”
—Friedrich Nietzsche (18441900)
“There is a quality even meaner than outright ugliness or disorder, and this meaner quality is the dishonest mask of pretended order, achieved by ignoring or suppressing the real order that is struggling to exist and to be served.”
—Jane Jacobs (b. 1916)
“History in the making is a very uncertain thing. It might be better to wait till the South American republic has got through with its twenty-fifth revolution before reading much about it. When it is over, some one whose business it is, will be sure to give you in a digested form all that it concerns you to know, and save you trouble, confusion, and time. If you will follow this plan, you will be surprised to find how new and fresh your interest in what you read will become.”
—Anna C. Brackett (18361911)
