Identifying the top brand of vitamins is challenging, because the Food and Drug Administration (FDA) does not regulate the vitamin and supplement industry. Due to this lack of regulation, people need to rely on either testing and ratings from independent, third-party organizations or companies’ own statements about their products.

In this article, we explain how some organizations assess the quality of vitamins and supplements. We also review some of the best brands.

Quick links

Dietary supplements, such as vitamins, are subject to limited evaluations from the FDA. Currently, the FDA does not review vitamins on the marketplace for safety, efficacy, or quality.

This means that vitamins may not contain the ingredients or dosage they claim to, 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.

It is of note, however, that the FDA takes action against adulterated or misbranded dietary supplements.

Third-party testing

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.

Some third-party organizations that assess vitamin and supplement brands include the Banned Substances Control Group (BSCG), ConsumerLab.com, and the NSF International.

Two of the most common certifications for vitamin brands are United States Pharmacopeia (USP) and #1 Pharmacist Recommended.

Medical News Today chooses products that meet the following criteria:

  • Price: Products suit a wide range of budgets.
  • Ingredients: Products list all ingredients clearly, with manufacturing processes outlined.

The following are common questions and answers about choosing the best vitamin brands:

How should a person choose the best vitamin brand for their needs?

To determine which vitamin brand is most suitable, an individual may try the following:

  • looking for proof of quality standards and testing
  • avoiding products with unnecessary ingredients
  • avoiding products making unsupported health claims
  • looking for third-party certifications
  • considering pricing options

A doctor or dietitian can offer guidance and advice for people with concerns about choosing the best vitamin brand for their health needs.

What certifications should people look for when choosing the best vitamin brand?

The following are third-party certifications that people can look for when choosing the best vitamin brands:

  • COA
  • USP
  • #1 Pharmacist Recommended
  • BSCG
  • NSF International
  • ConsumerLab.com

Such certifications demonstrate that a vitamin or dietary supplement brand has undergone third-party testing and evaluation for safety, efficacy, and quality.

What does ‘USP-verified’ mean?

The USP is an independent organization that verifies and certifies products that meet specific quality standards.

To gain USP verification, a product must:

  • not contain a certain number or quantity of contaminants
  • contain the ingredients on its label in advertised amounts and potencies
  • break down properly in the body

In addition, the company must follow the FDA’s CGMPs concerning sanitation and control.

What is the #1 Pharmacist Recommended seal?

For nearly 2 decades, U.S. News & World Report and Pharmacy Times have collaborated on an annual survey that goes out to pharmacists nationwide.

The survey asks pharmacists for their top picks of various healthcare-related products, including vitamins and supplements, and these are issued with seals. Anyone looking for this seal should be sure that it reflects the current year’s winning products.

A wide range of vitamin brands are available in stores or online. Researching various online reviews can help determine whether a brand offers good quality products.

Before a person makes a purchase, they should check whether the product has undergone a quality analysis. It may be best to opt for supplements that have third-party certifications.

Anyone interested in taking vitamins or other supplements should consult a doctor first.
