The Best Places to Buy Vitamins Online, According to a Dietitian

Shopping for vitamins and supplements online can be challenging, especially with so many options. Whether you’re looking for a particular product or just browsing for top-rate options, buying from a trustworthy retailer that offers high-quality supplements, dependable shipping, and fair prices is important.

A good place to start is to make sure the brand you're looking for has positive data on the U.S. Pharmacopeia and its products are independently verified by independent organizations like NSF, Informed Choice, ConsumerLab, or Underwriters Laboratories (UL). These organizations conduct their own testing to verify product quality and potency and to ensure what is stated on the label is actually what you're purchasing; they also test for heavy metals. Registered dietitian Kristin Kirkpatrick, MS, RDN, also recommends that you make sure the online distributor is either the supplement maker or a licensed seller, not an unknown third-party reseller.

To help you find the best places to buy vitamins online, we spoke with experts to learn what to look for in reliable retailers. Then, we researched dozens of sites, evaluating brands available, pricing and subscription models, cost and speed of shipping and returns, customer service, and more.

  • Have to pay attention to what store the supplements come from within Amazon

Amazon is the go-to for access to a massive variety of independently verified vitamin brands at competitive prices and fast free shipping. As of April 2024, Amazon requires independent verification for dietary supplements to ensure they meet safety and quality standards. Also, Prime members get fast, free shipping and exclusive deals. It's easy to track your packages online, and customer service is very responsive if you have any issues with your order. If you take a particular vitamin regularly, you can sign up for Subscribe & Save delivery, selecting the quantity and schedule that works for you so you never run out.

Many vitamin brands have their own store on Amazon, which ensures you're getting the supplement directly from the manufacturer and not a third-party seller. For example, if you take a Centrum multivitamin, check out the Centrum Amazon store.

While you should always follow your healthcare provider's recommendations for vitamins and supplements, the consumer reviews on Amazon are incredibly helpful in learning more about other people's experiences with products, product packaging, and other questions.

How We Selected the Online Vitamin Retailers

To find the best online vitamin retailers, we first spoke with experts to learn more about what sets different sites apart. During our research, we considered availability, range of high-quality vitamin and supplement brands, shipping dependability and price, added features, and customer reviews. We also looked at the turn-around rate of stocked vitamins and supplements.

We consulted with trusted peers in dietetics, including our team of registered dietitians. We spoke with:

What to Look for in an Online Vitamin Retailer

  • Transparency: When it comes to shopping for supplements, prioritize transparency—not just with individual products but with whole supplement stores. Make sure the store is clear about product storage, handling practices, and supplement sourcing. We also recommend choosing stores that sell supplements that have been independently verified, meaning the quality of the supplement has been tested by an independent organization not involved in its formulation or production.
  • Vitamin Brands: Choose a reliable website that offers the brand of vitamins that you prefer. If you're not sure which vitamin brand to purchase, many sites carry a variety of brands based on which vitamin you're looking to buy. For example, you can search for a non-GMO, organic vitamin C supplement, then select a brand at a price that works for your budget. As with all vitamins, always speak with your healthcare practitioner before adding a supplement to your routine.
  • Price: Vitamin prices vary from site to site. When shopping for an online vitamin retailer, select a site that offers the best price. If you're looking for a one-time purchase, almost any website will work; however, if you're looking to reorder a vitamin every month, a subscription model may be more affordable.
  • Product Turnover: Look for a site with a high turnover of products so that you can rest assured that you're getting the freshest, highest-quality vitamins available.
  • Shipping & Pick-Up: Many sites offer free shipping or in-store pick-up. Consider how soon you need the vitamin and shipping costs when deciding which website to use. A pick-up option may be the quickest, most affordable method for some consumers; however, some may prefer the convenience of delivery directly to your doorstep.
  • Return Policy: Be sure to check out the website's return policy in case you receive a broken vitamin bottle or decide you no longer need the product. Some sites offer full refunds in the mail or in-store, whereas others have limited supplement return options.

Frequently Asked Questions

Is it safe to order vitamins online?

If purchasing from well-known establishments, it is generally considered safe to order vitamins online. It is wise to first do research when choosing a place to purchase vitamins from. As a consumer, it is important to know what must appear on a supplement label. According to the FDA, five statements are required to appear on a label: the statement of identity (name of the dietary supplement), the net quantity of contents statement (amount of the dietary supplement), the nutrition labeling, the ingredient list, and the name and place of business of the manufacturer, packer, or distributor. If any of the above is missing, return the vitamin supplement. 

How can you tell if supplements are fake?

The unfortunate answer to this question is that you might not be able to tell if a supplement is fake. In some instances, it may be obvious. For example, if you are deficient in a vitamin and after taking the vitamin supplement your lab values do not change, you should question the authenticity of the supplement. However, other times, the answer might not be so clear. If you have taken a vitamin before with no side effects and suddenly you experience unwanted side effects, it might indicate something counterfeit. In addition, if the name and place of the manufacturer are missing from the vitamin bottle, it might indicate foul play.

Do vitamins expire?

The FDA does not require supplement companies to put an expiration date on their bottles, so any time you see a "use by" or "expiration" date, it has been added voluntarily. However, the potency of the vitamin or its individual ingredients may degrade over time, so it's recommended to follow the expiration date on the bottle.

At what age should you start taking vitamins?

This varies from person to person. Higher-risk groups may need to supplement earlier than others. For example, adolescents with heavy menstrual bleeding, young vegans or vegetarians, or children with deficiencies or malabsorption issues may benefit from taking supplements from a younger age. For healthy individuals who eat an adequate and varied diet, vitamin supplementation may never be necessary. As always, work with your healthcare provider to determine if and when supplementation is right for you. 

Is it cheaper to buy vitamins online?

The short answer is - not necessarily. Prices online and in store are generally the same; however, some retailers may offer discount codes website wide or on specific brands. Plus, given the option to subscribe, you can save a few bucks!
