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.

This means that vitamins may not contain the ingredients or dosage manufacturers claim they do, as contents may vary between batches.

Although the FDA requires vitamin manufacturers to follow Current Good Manufacturing Practices (CGMPs), this standard is not widely enforced.

That said, the FDA does take action against adulterated or misbranded dietary supplements.

Reputable vitamin brands use third-party testing

People can determine the quality of a vitamin or dietary supplement by looking for brands with certifications from 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:

  • the 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 NSF International.

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

The best vitamin brand will depend on a person’s needs. Different brands will often have unique selling points, and it is important for people find one that fits with their preferences.

However, whichever brand a person chooses, they need to read the product ingredients carefully and look for diligent testing processes and certifications.

Reputable vitamin companies will have rigorous testing procedures to ensure that their products contain the correct type and amount of nutrients and ensure there are no unsafe ingredients.

All of the brands in this article have passed Medical News Today’s own rigorous vetting standards.

Nature Made is a well known company offering affordable vitamin and mineral supplements. It offers bundle deals and subscriptions, so gives a variety of options to suit different needs.

It also has USP-verified products, meaning that their products meet federally recognized quality standards.

For nearly two 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 healthcare-related products, including vitamins and supplements. Successful products will feature a seal.

There are no standardized ingredients in multivitamins, which means each brand may differ. People should choose the multivitamin that best suits their needs.

People should look for multivitamins that carry a USP verification. This verification determines if the multivitamins are pure and contain the ingredients on the label.

People need to stay away from vitamin brands with unclear ingredient labeling. It is always a good idea to research the brand before making a purchase to ensure that the company is reputable.

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

Before making a purchase, a person needs to check whether the product has undergone a quality analysis. It may be best to opt for supplements with third-party certifications.

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