The supplement industry has grown into a $211.68 billion market in 2025, offering consumers over 50,000 different products worldwide. It’s easy to purchase supplements just about everywhere you shop these days. Though no supplement is a magic bullet, they can be helpful at filling in dietary gaps and offering therapeutic support. However not all supplements are created equal. Some fall short of meeting label claims and others have downright dangerous ingredients included. For these reasons, Kemper Cognitive Wellness is selective about the supplements we recommend and where to purchase them.
Some of the most common places supplements are purchased are at discount/drug stores like Walmart and third-party websites like Amazon. It might be tempting to go for a deeper discount or order online for convenience, but a supplement is only as good as the ingredients it contains.
Here are 5 things to consider when sourcing supplements:
- Product Testing. Oftentimes, when an independent lab report shows a supplement contain little to none of the active ingredients they claim, the brands are typically generic or from discount stores. Better supplement brands will not only conduct their own testing, but also require an unbiased third party to test their raw materials and finished product. This will guarantee that the manufacturer is meeting label claims.
- Ingredients Details. Simply stating the active ingredient and the milligram amount is not enough to ensure you are getting a product that has therapeutic benefit. Many manufacturers cut costs by adding the inactive parts of specific herbs and botanicals, or use synthetic vitamins and minerals. Ideally, the manufacturer not only identifies the active ingredients, but also the type of extraction, the potency per serving (not just a milligram amount), the parts used, and sourcing information for an herb or botanical.
- ‘Other’ Ingredients. When choosing a supplement, don’t forget to look for the “other ingredients” list. Many supplement manufacturers add fillers and artificial ingredients like talc, BHT, polyethylene glycol, modified corn starch and artificial coloring and preservatives. For example, the popular multivitamin brand Centrum contains around 20 of these “junk” ingredients, and they certainly aren’t the only brand. Not only are these ingredients unnecessary, but they can also be harmful. Furthermore, if a company is adding these ingredients, it calls into question the purity of the active ingredient itself.
- When you purchase a product from a third-party website (think Amazon or Ebay) you have no idea where it’s been kept, how long it’s been there, or if it’s been tampered with. If you are concerned about a supplement you have purchased, call the supplement manufacturer and give them the lot number. Though they won’t be able to give insights on how the product was stored, the manufacturer can identify the batch, verify the products seal is intact and let you know if a product is old or expired.
- The world of supplements can be quite overwhelming, and you will most likely need assistance in choosing the best active ingredients as well as a trustworthy brand. Most discount stores and third-party websites don’t have anyone available to answer your questions and help direct you to the best possible option.

Navigating the world of vitamins and supplements can be overwhelming, but taking the time to evaluate product quality, ingredients, and sourcing can make all the difference in supporting your health. With the supplement industry continuing to grow, it’s more important than ever to choose brands that prioritize transparency, rigorous testing, and high-quality ingredients. By purchasing from trusted sources—such as practitioner-recommended brands, reputable health stores, or professional-grade dispensaries like Fullscript—you can feel confident in the supplements you’re taking.
