We do the research so you can find trusted products for your health and wellness. Our team thoroughly researches and evaluates the recommendations we make on our site. To establish that the product manufacturers addressed safety and efficacy standards, we: Medical News Today only shows you brands and products that we stand behind.

How we vet brands and products

We include products we think are useful for our readers. If you buy through links on this page, we may earn a small commission. Here’s our process. This article discusses how some organizations assess the quality of vitamins and supplements and reviews some of the best vitamin brands a person may wish to consider. The Food and Drug Administration (FDA) does not regulate the vitamin and supplement industry, which can make identifying the top brands difficult. The best vitamin brands will provide a wide range of products and use third-party testing. Two of the most common certifications for vitamin brands are United States Pharmacopeia (USP) and #1 Pharmacist Recommended . Vitamins may have a certificate of analysis (COA), which declares that a product has undergone testing for safety and quality.

Products undergoing third-party testing may have undergone evaluation for:

Manufacturers can volunteer for third-party testing to indicate that their products are reliable and safe. People can determine the quality of a vitamin or dietary supplement by looking for brands certified by various third-party organizations. That said, the FDA does take action against adulterated or misbranded dietary supplements. Although the FDA does require that manufacturers of vitamins follow Current Good Manufacturing Practices (CGMPs) , this is not a widely enforced standard. This means that vitamins may not contain the ingredients or dosage manufacturers claim they do, as contents may vary between batches. Dietary supplements, such as vitamins, are subject to limited evaluations from the FDA . The FDA does not review vitamins on the marketplace for safety, efficacy, or quality.
