2 multivitamins that came up short

Whole Source Mature Adult (Rite Aid) and One Daily (The Vitamin Shoppe)

Samples of one of the three lots we tested of One Daily and samples of two lots of Whole Source Mature Adult failed to break down properly in our dissolution test. And samples of two of the One Daily lots contained less than 90 percent of their labeled level of vitamin A, considered the cutoff for an acceptable margin of error by the U.S. Pharmacopeia, which sets industry standards for dietary supplements.

Both products also exceeded the USP‘s upper limits for nutrients: One Daily contained more than 125 percent of its labeled calcium, while Whole Source had more than 125 percent of its labeled zinc and more than 165 percent of its labeled vitamin D. Those amounts don't pose a health risk, but they do raise concern about the products' quality. And at about 13 cents per day, they were the most expensive of all the multis we tested. There are better choices.
