What to Look for in an Online Vitamin Retailer


When it comes to shopping for supplements, prioritize transparency, not just with individual products but with supplement stores. Shoppers should be able to inquire about product storage and handling practices with direct answers to questions. Stores should be transparent about the sourcing of products and be able to answer questions about a product’s efficacy.

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 health care practitioner before adding a supplement to your routine.


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 that has a high turnover of products so that you can rest assured 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, there are five statements that 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?

    Vitamins do not expire in the same way food does. You will not see mold grow on vitamins that are kept past the expiration date. However, the potency of the vitamin may degrade over time. 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.

  • 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, orchildren with deficiencies or malabsorption issues may benefit from taking supplements from a younger age. For healthy individuals that 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!
