Best and Worst Multivitamins According to ConsumerLab – Nearly 30% Fail Testing
 
White Plains, New York, May 25, 2023 — Recent ConsumerLab tests revealed problems with nearly 30% of the popular multivitamin and multimineral supplements selected for testing. Gummy vitamins were particularly likely to have issues.

Seven of the 27 multivitamin/multimineral supplements ConsumerLab selected, purchased, and tested were found to contain far less, or far more, of a listed nutrient, including four gummy multivitamins selected for testing – several of which contained nearly double their claimed amounts of folate. In addition, one prenatal multivitamin was found to contain 88% more iodine than listed, a men’s multivitamin tablet failed to fully disintegrate within the allotted time in order to properly release its ingredients, and a pet supplement provided only 14% of its listed vitamin D.

Many ingredients are less stable in gummies than in capsules and tablets, leading manufacturers to add large overages, an issue ConsumerLab has identified in testing other gummy products. In fact, consumers may not be aware that, for this reason, USP standards for gummies are more lenient than for tablets and capsules. ConsumerLab, however, applies the same standards to gummies as to tablets and capsules.

ConsumerLab’s tests also showed that paying more for a multivitamin does not guarantee better quality. While the daily cost for a multivitamin ranged from just 3 cents to $1.00, several products on the higher end of this range were among those that failed testing.

Among products that passed all tests of quality and were Approved, ConsumerLab selected Top Picks, based on quality, appropriateness of dosage, formulation, and value, for each of the following categories:
