Not all supplements are created equal. Thanks to a lack of official regulation by the FDA, supplement companies can get away with cutting corners in production as well as sourcing, so it's well worth the extra time and money to purchase quality products.

One of the safeguards to ensure purity, strength, and identity of supplements are independent, third-party testing companies such as, NSF International, and U.S. Pharmacopeia. These organizations provide quality testing and allow products that pass their tests to display a seal of quality assurance that indicates the product was manufactured correctly, contains the ingredients listed on the label, and does not contain harmful levels of contaminants.

It is important to note, though, that these seals do not guarantee the product tested is safe or effective. When searching for the best vitamin brands, production practices, bioavailability, additives, and variety of available dosages should all be taken into consideration.

What to Look for in a Vitamin Brand

Quality Standards:

When choosing a vitamin brand, always double-check that the company complies with the cGMP standards set by the FDA. You can look for the cGMP certification logo on the bottle or do a bit of research online. This seal ensures that you are purchasing a high-quality, potent, and safely manufactured product.


Certifications—such as USDA Organic, Certified Vegan, Non-GMO Project Verified—provide reassurance that the brand produces high quality, potent vitamins. Consider your individual needs when choosing a vitamin brand. For example, if you are vegan, you may prefer choosing a Certified Vegan supplement. If you avoid gluten, a Certified Gluten-Free or NSF Gluten-Free vitamin may be best for you.


Look for a brand that independently tests all of their raw ingredients and finished products. If you're unable to find this information, look at third-party supplement testing information published on websites such as and


Fortunately, a high price tag doesn't necessarily mean better quality. There are many great wallet-friendly vitamin brands on the market. If you have a bigger budget for vitamins, you may want to consider a brand that offers the most bioavailable form of a specific vitamin or a highly tested product.

Klaire Labs offers a wide range of clean, pharmaceutical-grade formulations that are known for their purity and potency. Founded by Claire Farr in 1969, the supplement brand is a model for premium, professional-grade supplements, including vitamins.

Solgar has been in the dietary supplement industry for over 70 years. As a trusted source for supplements that are free of harmful additives and common allergens, Solgar is a top pick for those looking for affordable, effective vitamins for the whole family.

Good to Know

One practice the FDA has put into place to regulate the supplements industry is the establishment of good manufacturing practices (GMPs) that companies must follow to help ensure the identity, purity, strength, and composition of their dietary supplements. The FDA periodically inspects facilities that manufacture supplements.

Thorne is deeply rooted in clinical research. The company partners with research organizations around the world, including the Cleveland Clinic, Columbia University, Mayo Clinic, Mount Sinai, and more. These scientific collaborations confirm the safety and efficacy of Thorne’s products and contribute to a broader goal of accelerating science in the health and wellness space.

Thorne’s facility is NSF- and cGMP-compliant, and they rigorously test for 760 contaminants to verify the identity, potency, and purity of each ingredient listed on their product labels. They offer a wide range of supplements, including multivitamins and specific individual vitamins. If you’re an athlete, Thorne makes NSF Certified for Sport supplements that are trustworthy, compliant, and used by major athletic organizations such as USA Triathalon, US Rowing, and USA Hockey.

The company also offers at-home testing kits for key biomarkers to identify common vitamin deficiencies such as vitamin D.

Megafood is one of the most trusted brands in the supplement industry because of its commitment to transparency. Consumers can head to Megafood’s website and observe product production live 24/7. The products also meet the highest standards for ecological and social sustainability, as well as quality and purity, as reflected by nine certifications.

Megafood is also true to its name and is genuinely “fresh from farm to tablet.”  Their proprietary FoodState Nutrients™ combine with added vitamins, minerals, and binders to create highly effective, whole-food supplements.

NOW Foods' manufacturing process is cGMP. NOW was one of the first manufacturers in 2000 to seek GMP certification, and the company has maintained an A rating since then.

Pure Encapsulations offers one of the most comprehensive selections of hypoallergenic vitamins and minerals. Devoted to ingredient purity, quality testing, and consumer trust, Pure Encapsulations independently tests all raw materials and finished products to ensure that each step of their production process is consistent with their high standards.

Transparency is key for Pure Encapsulations, and the company works hard to ensure most products are free from wheat, gluten, egg, peanuts, trans fats, hydrogenated oils, GMOs, magnesium stearate, coating and shellacs, artificial ingredients, and unnecessary incipients. Note that some products are derived from major allergens such as soy, dairy, and shellfish. These products are prominently labeled. It’s also an excellent choice for those who avoid gluten, as over 300 products are Certified Gluten-Free by GFCO.

Garden of Life

Traceability is key to Garden of Life’s brand. The company is conscious to know where the ingredients come from, the farming practices used, and even how the workers are treated. This devotion to clean, organic, food-based supplements is reflected in the multitude of third-party certifications that the company has: USDA Organic, Non-GMO Project Verified, Certified Vegan, Certified Gluten-Free, NSF Gluten-Free, Star-K Kosher, OU Kosher, NSF Certified for Sport, and Informed Choice. The brand is also a Certified B Corporation and meets the highest standards of renewable energy and green building practices.
Garden of Life produces a variety of vitamins, including gummies, multivitamins, prenatals, and targeted nutrients that are all made from organic, whole-food ingredients. Many of the supplements are raw, meaning they are produced below 115 degrees Fahrenheit to protect their natural cofactors and complementary probiotics and enzymes. This ensures that they are as close to the raw, whole food form as possible.

Innate Response Formulas

Innate Response Formulas is one of the first supplement companies to guarantee that their products are glyphosate residue-free, which increases the efficacy of their multivitamins. Glyphosate, a key ingredient in the weed killer Roundup, has been making headlines recently due to its negative effects on hormones, gastrointestinal health, respiratory health, and immune functioning, among other concerns. 

In addition to glyphosate, each batch of incoming ingredients is tested for over 125 different pesticides and herbicides. With a variety of multivitamins for men and women, consumers of all ages can rest assured that their specific needs will be covered with this supplement.

What Experts Say

"Certifications and independent testing labels are two important factors when choosing a vitamin brand. Supplements are not regulated by the FDA so it is up to brands to put forth the effort to ensure purity and potency through extra testing. Look for any of the following labels: NSF, GMP, Consumer Labs, or USP." —Sydney Greene, MS, RD

Why Trust Verywell Fit?

A personal note on my recommendations written above. As a dietitian, I am cautious to recommend supplements, including vitamins. I believe the products in the round-up are made by trusted brands and are composed of high-quality ingredients. I would recommend the above brands to friends, family, and clients, and have personally tried vitamins from each brand. You can currently find Solgar, Megafood, and New Chapter vitamins in my medicine cabinet. Eliza Savage, MS, RD, CDN
