The 10 Best Vitamin Brands of 2025, Reviewed by a Registered Dietitian

Everyday Health independently vets all recommended products. If you purchase a featured product, we may be compensated. Learn why you can trust us.
Vitamins and supplements are a big business. In the United States, it’s a $41 billion market that is growing every year — and worldwide, it’s a $146 billion industry that’s expected to reach $250 billion by 2035.

 In many ways, this makes sense. More than half of American adults — 58 percent to be exact, according to the Centers for Disease Control and Prevention (CDC) — are currently using dietary supplements as part of their daily wellness routine.

With hundreds of different vitamin brands on the market, there is no one-size-fits-all option. Additionally, because the U.S. Food and Drug Administration (FDA) does not fully regulate the supplement industry, not all supplements are manufactured with the same stringent regulations as medications or even food items.

However, certain companies volunteer their products to undergo third-party testing — through such agencies as the National Science Foundation (NSF) and U.S. Pharmacopeia (USP) — which is considered the gold standard, to ensure supplement safety and efficacy.

To help you determine which vitamin and supplement brands are best, we did the research and asked experts what they look for when selecting their preferred vitamin brand. “I look for brands that perform third-party testing, have only necessary fillers, binders, and preservatives, and are reasonably priced,” says Seema Shah, RD, MPH, owner and principal dietitian at Seema Shah Integrative and Functional Nutrition in Long Beach, California. Other factors we considered when creating this list include the bioavailability of nutrients and brand awareness.

Here are our top vitamin brand picks.

Our Top Picks for Best Vitamin Brands

When to Consult Your Doctor

While vitamin and mineral supplements can benefit your health, complementing your current dietary intake to better meet your nutritional needs, they can also cause harm if taken inappropriately. It is important to consult a healthcare provider when considering adding any new vitamin supplement to your daily routine, to ensure that you fully understand all the risks and benefits associated.

As previously noted, dietary supplements are not fully regulated by the FDA. There are additional third-party tests and certifications to look for to ensure that the supplement you are considering is exactly what it says it is. We will dive into this topic a bit later.

Best Gummy

SmartyPants

Pros

  • Third-party tested
  • Free of the eight most common allergens
  • Wide range of supplement options for the entire family
  • Easy to chew
  • Certified organic options

Cons

  • Gummies contain added sugar, which can impact dental health
  • Third-party tested: Yes
  • Free of: Gluten, soy, dairy, egg, peanut, tree nuts, and artificial flavors
  • Non-GMO: Yes
  • Price range (three-month supply of multivitamin): $21.99

Gummy vitamins are a fun, easy way to take supplements when capsules or tablets are not for you. We trust SmartyPants to make tasty, beneficial vitamin gummies because the brand is transparent about its entire manufacturing process. The company discloses where it sources its ingredients (so you can always know exactly where each ingredient in your product came from with one click on the website), what manufacturing guidelines it follows, and what internal and third-party tests the products go through. Additionally, all SmartyPants supplements are free of the eight most common allergens and are made without synthetic colors, artificial flavors, sweeteners, or preservatives.

SmartyPants also has third-party testing certificates from various outside organizations, including the NSF, a public health and safety organization that provides testing to ensure safety and label claims; the Non-GMO Project, a nonprofit organization dedicated to ensuring Americans know exactly what is in our food and supplements; and the Clean Label Project Purity Award, which evaluates products for substances such as chemicals, environmental toxins, and contaminants.

We also like that SmartyPants gummies offer an array of supplements that can meet the needs of your entire family (as long as they’re over the age of 3), including Kids & Toddlers Multi, Teen Girl Multi & Omegas, Adult Formula, and Masters Women 50+ Formula. Smarty Pants also offers a certified organic collection and vegetarian options with omega-3 supplements made from organic flaxseed oil instead of fish.

One drawback to SmartyPants gummy vitamins and supplements is that they contain added sugar for flavor, which can increase your risk of tooth decay.

Fortunately, the company primarily uses organic cane sugar and is always looking for ways to lower the total sugar content without impacting the taste or stability of its products.

Best Budget-Friendly

Nature Made

Pros

  • Third-party tested
  • Over 150 different products
  • Widely available online and in stores
  • Affordable

Cons

  • Some formulas have more than the recommended daily value
  • Some vitamins contain milk, eggs, fish, and peanuts
  • Third-party tested: Yes
  • Free of: Most products are gluten-free
  • Non-GMO: Not all products
  • Price range (three-month supply of multivitamin): $41.94

If you’re looking for a quality vitamin or supplement on a budget, Nature Made is our pick. When comparing multivitamins, a 90-count bottle of Nature Made Multi for Her costs $13.59 ($0.15 per serving) and will last 90 days, whereas SmartyPants Women’s Multi-Vitamin 60-count bottle is a one-month supply at $13.98 ($0.46 a serving). Along with being affordable, Nature Made vitamins and supplements come in a variety of forms and are easy to find at popular retailers like Costco and Target, pharmacies like Walgreens and CVS, as well as online at Nature Made and Amazon.

Julie Pace, RDN, owner of Core Nutrition Health and Wellness, says she often recommends Nature Made vitamins to her patients because many come in a variety of dosages, which allows her to personalize recommendations to each patient. She also highlights that Nature Made is an established brand with USP third-party testing certificates on several products (full list here). Not only that, but some of Nature Made’s products have also gone through clinical trials, with the results and data posted on the Nature Made website — such as vitamin D in the VITAL randomized controlled trial in 2021.

However, be sure to check the label and speak to your healthcare provider when choosing and starting a Nature Made vitamin or supplement, because some of its products contain well above the recommended daily value of some ingredients as set forth by the FDA.

 This isn’t always a bad thing; for example, if someone were deficient in a particular vitamin or mineral, supplementation would likely be advised, under the care of a healthcare provider. But when vitamin and mineral supplements are improperly dosed, it can potentially lead to severe health risks, which is why we recommend being extra cautious.

 It is also important to note that some of Nature Made’s supplements do contain common allergens, including milk, eggs, fish, and peanuts.

Best Allergy-Friendly

Pure Encapsulations

Pros

  • Third-party tested
  • Free from common allergens
  • Non-GMO, and free of artificial colors, flavors, and sweeteners
  • Most supplements are certified gluten-free

Cons

  • Many products are higher in price
  • Third-party tested: Yes
  • Free of: Gluten, soy, dairy, eggs, tree nuts, peanuts
  • Non-GMO: Yes
  • Price range (three-month supply of multivitamin): $64.50

With over 400 unique formulations designed to support a wide range of benefits, Pure Encapsulations is a supplement brand to keep on your radar if allergies are a concern for you or your family. All Pure Encapsulation supplements are free of common allergens, including wheat, soy, dairy, eggs, tree nuts, and peanuts. We appreciate that Pure Encapsulations lists all ingredients on its product labels (even if it is only a trace amount). Its products are also tested by independent labs, and many of them (including their O.N.E. Multivitamin) are non-GMO; free of artificial colors, flavors, and sweeteners; and certified by the Gluten-Free Certification Organization.

With many of its products nearing the $1 per serving category, Pure Encapsulations is on the higher-priced end, compared with other supplements on the market. If you’re looking for high-quality products, free of specific allergens, with a variety of supplements to choose from, and are willing to pay a bit more compared to other companies, Pure Encapsulations is a good choice.

Best Vegan

Garden of Life

Pros

  • Multiple third-party testing certificates
  • Wide range of certified vegan products
  • Non-GMO
  • Many supplements use whole food ingredients

Cons

  • Not all products are vegan, so be sure to check the labels
  • Some vitamins may contain peanuts and tree nuts
  • Third-party tested: Yes
  • Free of: Artificial colors, flavors, binders, and fillers
  • Non-GMO: Yes
  • Price range (three-month supply of multivitamin): $81.57

Garden of Life sets itself apart from many supplement companies because its products are certified by several third-party organizations, including USDA Organic, Non-GMO Project, and NSF Gluten-Free. Garden of Life holds itself accountable by focusing on whole food ingredients, transparency, and traceability in those ingredients, without artificial flavors, colors, binders, or fillers.

In addition, not only is Garden of Life focused on its third-party certifications when it comes to product purity and safety — they are also committed to sustainability. Garden of Life is also certified carbon neutral, B-Corp certified, LEED Gold certified, and Upcycled certified, as the company claims to use recyclable packaging and post-consumer recycled bottles when able.

With 164 total vegan products available, there are many supplements to choose from if you follow a vegan lifestyle, such as Garden of Life Organic Men’s Once Daily. That said, Garden of Life has more than 300 products in total, so be sure to read the labels carefully to confirm that the product you’re purchasing is vegan. If allergies are a concern, specifically peanuts or tree nuts, Garden of Life recommends avoiding the use of their products, as they do not test finished goods for the intentional or accidental presence of nuts, peanuts, or tree nuts.

Best Prenatal

Perelel Health

Pros

  • Third-party tested
  • Clean Label Project Purity Award winner
  • Research-driven dosages specific to pregnancy
  • Free of gluten, soy, dairy
  • Non-GMO
  • Pregnancy-specific daily vitamin packs for added convenience

Cons

  • Higher priced than other prenatal brands
  • Limited options for vegan and vegetarian lifestyles
  • Third-party tested: Yes
  • Free of: Gluten, soy, dairy, artificial colors, and fillers
  • Non-GMO: Yes
  • Price range (three-month supply of multivitamin): $148.50

When it comes to pregnancy, Perelel has a definite edge because it was founded by two ob-gyns who wanted to give pregnant women more personalized supplement support for each stage of pregnancy. As a result, it sells convenient daily vitamin packs that adjust and modify ingredients to meet changing nutrient needs in each trimester. For example, for the first-trimester pack, you’ll get an anti-nausea blend, but in the second trimester, the blend contains added magnesium to support muscle cramps and relaxation, and in the third trimester, the packs are formulated with added probiotics to support gut health. This stage-specific approach is unique in the prenatal space.

While the trimester-specific pregnancy support vitamins really make this brand stand out, this is not their only offering. Perelel also makes supplements to support preconception, postpartum, perimenopause, daily wellness, and men’s health.

In addition, all Perelel’s products are recognized by the Clean Label Project, and they are third-party tested, non-GMO, and free of soy, gluten, artificial colors, and fillers. It’s worth noting, though, that with the more personalized approach to pregnancy comes a higher price tag, at $49.50 for a 30-day supply. To absorb some of that additional cost, you can opt-in for a monthly recurring subscription when purchasing your daily pregnancy packs, providing a 15 percent discount.

Best Sustainably Sourced

Nordic Naturals

Pros

  • Third-party tested
  • Certified sustainable by Friend of the Sea, and LEED Gold certified
  • Products backed by research
  • Many products are non-GMO and free of gluten and dairy

Cons

  • Limited selection of product variety compared to other brands
  • Third-party tested: Yes
  • Free of: Gluten and dairy
  • Non-GMO: Yes
  • Price range (three-month supply of multivitamin): $80.85

Nordic Naturals prides itself on its sustainability practices in both ingredient sourcing and product manufacturing, and its LEED Gold certification further demonstrates the company’s commitment to sustainability practices. With certificates of analysis (COAs) available on all products from Friend of the Sea, the leading certification standard for products that respect, protect, and promote marine and environmental conservation, Nordic Naturals’ focus on purity, potency, and transparency ensures that you are getting exactly what the label states, without heavy metals, environmental toxins, or other potential contaminants.

While Nordic Naturals is best known for its omega-3 fish oil supplements, it also offers select vitamin and mineral options and probiotics as well. Currently, its product formulary includes products suitable for children, adults, seniors, athletes, and pets. With just over 100 products in their arsenal, they offer a variety of high-quality vitamins; however, when compared to other supplement brands, the total offerings are more limited.

Veronica Rouse, a registered dietitian with WowMD, says, “I am a big fan of Nordic Naturals … because they produce high-quality supplements while promoting environmental sustainability. Their omega-3 supplements are sourced from wild-caught fish, which protects marine ecosystems. They are also third-party certified by organizations like Friend of the Sea and Marine Stewardship Council, ensuring eco-friendly fishing practices that protect our oceans.”

Best for Children

Hiya

Pros

  • Third-party tested, with COAs available
  • No added sugar or other additives
  • Refillable nonplastic packaging
  • Chewable, suitable for children ages 2 and up

Cons

  • Limited ways to purchase
  • Higher price
  • Third-party tested: Yes
  • Free of: Gluten, dairy, soy, fish, eggs, tree nuts, peanuts, added sugar, and additives
  • Non-GMO: Yes
  • Price range (three-month supply of multivitamin): $90

We chose Hiya as the best children’s vitamin brand because the company’s first focus is on safety, which is always a top priority for parents. With rigorous quality standards, Hiya performs testing at various stages of manufacturing to ensure a quality product, including comprehensive screening for heavy metals and microbial contamination. Additionally, COAs are available for every product on the company’s website.

For flavor, instead of adding sugar to its children’s chewable supplements, Hiya sweetens its vitamins with a blend of monk fruit extract and mannitol. Since 2010, monk fruit, a small fruit native to southern China, has been increasing in popularity as an alternative sweetener in various food categories.

In addition to a kid’s daily multivitamin, Hiya also offers a daily probiotic, a children’s bedtime essentials supplement (melatonin-free), a daily iron supplement, and a daily greens/superfood powder. Also noteworthy, as a minimal waste product, the company offers refillable glass containers or eco-friendly pouches (specific packaging depends on the product).

With its direct-to-consumer business model, Hiya supplements will be shipped right to your door. However, for some, the limited ways to purchase may make these products tougher to obtain.

As with any new supplement, it is recommended that you consult a qualified healthcare practitioner before offering it to your child (or yourself) to ensure that the product is necessary and appropriately dosed.

Best Subscription-Based

Ritual

Pros

  • First-month discount
  • Cancel subscription anytime
  • Products are non-GMO and free of major allergens
  • Transparent ingredient sourcing

Cons

  • Somewhat pricey
  • Serving size is two large pills
  • Third-party tested: Yes
  • Free of: Gluten, dairy, soy, fish, eggs, tree nuts, peanuts
  • Non-GMO: Yes
  • Price range (three-month supply of multivitamin): $99

If you’ve ever reached for your vitamins only to realize you forgot to buy a refill, a subscription plan might be what you’re after — and Ritual is our favorite of all the companies that offer this type of monthly service. While Ritual does offer single-purchase items in addition to its subscription approach, if you sign up for recurring orders, you’ll get a 25 percent discount on your first month’s order, a money-back guarantee if you are unsatisfied, the ability to easily cancel your subscription at any time, and the peace of mind that you’re not going to forget to pick up a refill.

Ritual is also unique in that each supplement capsule incorporates both liquid and solid components. This is meant to allow for delayed release and enhanced absorption of vital nutrients. Ritual also offers transparent sourcing of its ingredients, listing each ingredient and where in the world it’s sourced from. The company also conducts both internal and third-party testing. All products are non-GMO and made without gluten or major allergens.

Best for Athletes

Klean Athlete

Pros

  • Third-party tested
  • All products are NSF Certified for Sport
  • Non-GMO and free of gluten, artificial flavors, colors, and sweeteners

Cons

  • Higher priced
  • Third-party tested: Yes
  • Free of: Gluten, artificial flavors, colors, and sweeteners
  • Non-GMO: Yes
  • Price range (three-month supply of multivitamin): $132
Klean Athlete is a supplement brand that is popular with people involved in sports — and we can see why. All of its products are third-party tested, non-GMO, and free of added flavors, colors, and sweeteners. Not only that, but its products — including its vitamins, minerals, electrolytes, protein powders, pre- and post-workout supplements, and creatine — are all specifically geared toward athletes to help them with their performance and recovery.

The brand is also NSF Certified for Sport, which means it was tested to ensure its products do not contain unsafe levels of contaminants, banned substances, masking agents, or ingredients not listed on the label.

While Klean Athlete products hit the mark when it comes to purity and testing for athletes, the price tag is on the higher end. As an example, the Klean Multivitamin comes in at $44 for a 30-day serving, or roughly $1.47 a day.

Best Personalized

Hum Nutrition

Pros

  • Third-party tested
  • Clean Label Project and non-GMO certified
  • Personalized product recommendations
  • Access to RDNs for support
  • Free of artificial colors, flavors, and sweeteners

Cons

  • Some product claims are not supported by clinical evidence
  • Third-party tested: Yes
  • Free of: Artificial flavors, colors, and sweeteners
  • Non-GMO: Yes
  • Price range (three-month supply of multivitamin): $45

Hum Nutrition is our top pick for those interested in personalized vitamin brands. Hum offers tailored product recommendations based on a quick health quiz through its website. The quiz assesses basic health information, including your history, eating style, and health goals. One of the company’s more unique offerings is access to a Hum Nutrition staff RD, who can provide you with a comprehensive health report that provides diet and lifestyle advice, specific product recommendations based on your areas of concern, as well as one-on-one support with any of the company’s products.

Hum Nutrition offers vitamins, minerals, omega-3s, probiotics, and herbs in various forms, including gummies, tablets, soft gels, and powders. Its products are free of artificial flavors, colors, and sweeteners. Hum Nutrition supplements are also third-party certified by the Clean Label Project and Non-GMO Project, guaranteeing they are free of contaminants, heavy metals, and GMOs.

In addition to a targeted, RD-supported approach to a personalized supplement routine, Hum’s product packaging is made up of 100 percent recyclable materials.

We really like the tailored approach Hum Nutrition offers, but it is important to note that there are a handful of products making specific claims that are not entirely supported by clinical evidence. For example, Skinny Bird claims to reduce appetite; however, a randomized controlled study assessing the potential for weight loss involving the primary ingredient (Caralluma fimbriata) utilizes a larger dose of the ingredient than what is found in Hum’s product.

 This is just another reminder that supplements can complement your current diet and lifestyle but should not replace certain food groups, nutrients, or exercise goals.

What to Look for When Buying Vitamins

With the abundance of vitamin brands currently on the market, it’s important to take the time to choose the one that is best for you as an individual. While brand familiarity is always a bonus, it is not everything. When choosing the best vitamin brand for you and your family, a few things to look for include:

  • Third-party testing: Since the FDA doesn’t fully regulate the supplement industry, Rouse states, “The most important thing when recommending vitamin brands to clients is third-party testing to ensure the supplement contains what it claims.” Third-party testing verifies that supplements match their label claims, free of contaminants such as heavy metals, and that the nutrients are in bioavailable form.
  • Artificial additives: Flavors, colors, and fillers (the fewer, the better)
  • Price: Keep your budget in mind, as vitamin pricing can vary greatly, ranging anywhere from $40 to $140 for a 90-day supply.
  • Dosing: Vitamin and mineral supplements are meant to complement your dietary intake, not replace it. Finding a supplement that meets your specific needs is critical, and it is recommended that you consult a qualified healthcare professional when doing so.
  • Sugar: Sugar is sometimes added to improve the taste of supplements. As sugar can increase your risk of tooth decay, it is important to find a supplement with limited or no added sugar, if possible.
  • Allergens: If you have food sensitivities, it’s important to read the label of any supplement you are considering, not only for included ingredients but also for cross-contamination risk during the manufacturing process.

What Are Some Credible Third-Party Testing Organizations?

Organizations that offer third-party testing for supplements include:

  • NSF International A product testing, inspection, and certification organization for public health standards.
  • NSF for Sport An independent third-party certification program helping athletes make safer decisions when choosing sports supplements.
  • USP An independent, scientific nonprofit organization that aims to help protect patient safety in the world’s medicines, dietary supplements, and foods.
  • ConsumerLab An organization that evaluates consumer products related to health, wellness, and nutrition, providing independent test results and information to help consumers and healthcare professionals identify the best quality products.
  • Informed Choice A global quality assurance and third-party supplement testing program designed to minimize the risks of dietary supplement products from contamination with prohibited and potentially harmful substances.

Are Supplements FDA-Approved?

No, dietary supplements are not approved by the FDA for safety or effectiveness.

 The FDA does periodically inspect manufacturing facilities to that ensure they are in compliance with Current Good Manufacturing Practice guidelines, which is why you may see some companies report that they are cGMP.

Third-party testing, by reputable and qualified laboratories, is the gold standard to ensure the purity and safety of supplements.

How Do I Know I Am Choosing the Right Supplement for Me?

Choosing a dietary supplement is no easy task. The National Institutes of Health emphasizes that dietary supplements are intended to complement your existing dietary intake, not replace it.

I strive for my patients to meet their nutritional needs with food; however, this is not always possible. Dietary supplements, when appropriately dosed, can fill those nutritional gaps.

To ensure that you are choosing the most appropriate supplements for you and your family, it is important to speak with a qualified medical professional. Your primary care physician (PCP) or a registered dietitian is a great place to start when discussing new dietary supplements. You will likely be asked questions about your current dietary intake, any existing medical conditions, medications you’re currently taking, and any allergies you may have. Your provider will then review various supplements and their ingredients, focusing on dosing, bioavailability, potential medication interactions, and other safety risks. All of these factors play a role in uncovering which supplements may be right for you.

FAQs

How do I know which vitamin brand is best?
Vitamin brands are not one-size-fits-all, so there are a few things to consider when choosing the best vitamin brand for you. Start by including your PCP or a registered dietitian in your search to ensure that a supplement is necessary. Next, look for brands that are third-party tested, as this is the gold standard to ensure supplement safety and efficacy. Review the label and look for brands with limited sugar and artificial additives such as flavors, colors, and fillers. Find a brand that is within your price point, and if allergies are a concern for you, be sure to check the label for those as well.

Third-party testing is voluntary testing some supplement companies opt for, and it is considered the gold standard for ensuring supplement safety and efficacy. Third-party testing verifies that supplements match their label claims and that the nutrients are in a bioavailable form and are free of contaminants such as heavy metals. When reviewing various supplement brands, look for symbols on the bottles or on the company’s website highlighting any of the below organizations that offer third-party testing:

  • NSF International
  • NSF for Sport
  • USP
  • ConsumerLab
  • Informed Choice

In short, yes, it does matter where you buy your vitamins. ConsumerLab stresses “the importance of proper storage conditions for supplements, as many can degrade faster and lose effectiveness when exposed to excessive heat, light, oxygen or humidity.”

Most supplements should be stored in a cool, dry place to prevent nutrient degradation. Some supplements, such as probiotics, may also need to be refrigerated. As a result, you will want to find retailers where you can go in and purchase these items, to ensure proper storage and handling conditions. If you prefer to have supplements shipped, it is recommended that you have those items shipped with cold packs if you live in a hot, humid environment during the summer months.

Yes, taking different vitamin brands together is usually fine. However, this is another reason why involving your PCP or a registered dietitian would be helpful, as some supplements may interact with one another, compete for absorption, or interact with certain medications. When reviewing your total supplement intake with a healthcare provider, be sure to bring in all your supplements and medications and accurately describe your current dosing schedule. Your healthcare provider will review for any potential bioavailability concerns, toxicity concerns, and drug interactions.
