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.
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.
A quick look at the best vitamin brands:
Dietary supplements, such as vitamins, are subject to limited evaluations from the
This means that vitamins may not contain the ingredients or dosage manufacturers claim they do, as contents may vary between batches.
Although the FDA does require that manufacturers of vitamins follow Current Good Manufacturing Practices (CGMPs), this is not a widely enforced standard.
That said, the FDA does take action against adulterated or misbranded dietary supplements.
People can determine the quality of a vitamin or dietary supplement by looking for brands certified by various third-party organizations.
Manufacturers can volunteer for third-party testing to indicate that their products are reliable and safe.
Products undergoing third-party testing may have undergone evaluation for:
- standardized quality between batches
- correctly stated dosage
- ingredient purity
- potentially harmful contaminants
- label transparency
Vitamins may have a certificate of analysis (COA), which declares that a product has undergone testing for safety and quality.
