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.

Rather, it is the quality of their interpersonal relationships and their transactions with the wider social and material environment that lead to behavioral, emotional, and physical health problems. If stress matters, it is in terms of how it influences the relationships that are important to the child.”
—Felton Earls (20th century)
