How We Test Products

At Verywell Fit, our goal is to help you learn how to live a happier, healthier life. And when it comes to purchasing decisions, you deserve peace of mind. That’s why we take caution and care with every product we research, rigorously test, and ultimately recommend. 

We do market research, interview industry experts, and test products within a comprehensive methodology in The Verywell Testing Lab and in the comfort of testers’ homes to give you product recommendations you can trust. While we do receive affiliate commission on some of the products purchased through our content, our recommendations are curated based on performance, test results, and hands-on experience.


How We Test, Evaluate, and Rate Hundreds of Products Every Month

Our Testing Process

Prior to testing products, our team of writers and editors exhaustively researches the marketplace and interviews industry experts—including certified trainers, physical therapists, board-certified physicians, and registered dietitians on what to look for when buying particular products. From there, we develop detailed testing methodologies that help us rate products based on attributes like ease of set up, value, performance, and more. These attributes are displayed on a one to five scale next to each product. Next we come up with a selection of products to test that cover the gamut of retailers, prices, user reviews, brand authority and such. While we may receive some products for free, we purchase the vast majority of the products that we test. 

In addition to the objective testing results, we also weigh qualitative insights: How easy is it to actually adjust the adjustable dumbbells from one set to the next? Did the yoga mat maintain its grip under sweaty palms and feet? We take it upon ourselves to editorialize the performance data in order to provide easy-to-understand reasons you can trust our recommendations. We highlight the pros and cons of a product so you can weigh the most important details for your lifestyle and needs and make the most informed decision.

Please note that all products, including those we review and recommend, may from time to time be subject to recalls or revised use recommendations. We, therefore, urge you to monitor any official announcements from the Consumer Product Safety Commission (CPSC) that may be related to products you purchase.

We are dedicated to ensuring that our content reflects the diversity of our audience. To do this, we make a point to research brands and products founded by people who identify as BIPOC (Black, Indigenous, People of Color) and other minority groups whenever possible. Read our full commitment to anti-racism.

Testing in The Lab

The Verywell Testing Lab—our testing facility in Manhattan, NY—has over 7,000 square feet and two test kitchens. In The Verywell Testing Lab, we test everything from yoga mats to adjustable dumbbells side by side in order to see how they compare to one another. During each test, we are capturing the unboxing, setup, and comments of our testers in photos, videos, and written content to provide you with the most comprehensive and behind-the-scenes look at what our tests look like and how the products held up.

Our editors, writers, and producers test products alongside trained professionals and experts (we have certified personal trainers scrutinizing every detail of adjustable dumbbells) using standardized methodologies. And we get creative with our tests, too. When testing adjustable dumbbells, we take them outside and drop them on the sidewalk so you know how well they hold up both indoors and out.

Testing At Home

We recognize that not every product lends itself to testing in The Verywell Testing Lab; this is where at-home testing comes in. We know that products require real-life testing and some data can only be collected in a real-life situation. With at-home testing, we’re able to vet things like delivery and setup and monitor how things hold up over time: How well does the cushioning on running shoes hold up after five miles versus 50 miles? Do the belts on a treadmill maintain their traction? Will leggings lose their compression, elasticity, or opacity with repeated washing?

Our at-home testing process consists of editors, writers, and experts following the same kind of detailed methodologies we use in The Verywell Testing Lab. They fill out surveys rating each product for key attributes, provide helpful insights on each product, and capture photos and videos of how the products perform in real-life.

How We Evaluate Dietary Supplements

Dietary supplements may, in certain circumstances: improve overall health by preventing nutrition gaps, replete levels of a diagnosed deficiency, and help manage specific symptoms or health conditions. But while supplements can help do these things, they pose potential risks due to lack of regulation and improper usage.  It is possible to take too much, to create a nutrient imbalance from improper usage, and for supplements to interact with other supplements or prescribed medications.

It is best to get our nutrients from the foods we eat, and supplementation is only useful when nutrient needs cannot be met through the diet. Even if the manufacturer website makes big promises, this does not mean these claims are supported by research. Supplements are not intended to treat, prevent, or cure conditions or diseases—they will not solve any physical or mental health conditions aside from those caused by deficiencies. There are no recommendations for the general population regarding supplements because each person’s needs and risk of deficiency is different—there are no supplements that are beneficial for everyone.

In the United States, the FDA does not regulate supplements or approve them for safety and efficacy before they are marketed to the public.

We only recommend dietary supplements that are evidence-based, meaning there are a substantial number of good quality studies to support a recommendation. If there is research that makes us skeptical about safety, we will not recommend that product.. We are cautious around our recommendations and examine these products at the individual ingredient level. Among our recommendations, you will not find: supplements with claims that are unsupported by clinical research, supplements that are potentially dangerous (beyond the typical risks associated with nutritional supplements), weight loss supplements (this includes diet pills), supplements with sexual enhancement claims, or any exercise or sports performance products that may be harmful to athletes.

We prioritize products that have been third-party tested and certified by one of three reliable organizations—NSF, USP, or ConsumerLab—and we will always highlight whether or not each product is third party tested and certified. Since the FDA does not regulate the supplement industry, third-party testing helps ensure that a product contains what it says it contains and is not contaminated with other ingredients, though it says nothing about efficacy. These certifications can be expensive, so, if a supplement is not third-party tested or certified, it doesn’t automatically mean that it is not a good product. 

In addition to these strict standards, we closely examine the supplement facts label for attributes we value. These include products that are non-GMO, organic, free of unnecessary additives, and minimally sweetened.Our methodology and recommendations for dietary supplements is not intended to be a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health provider with any question you may have regarding dietary supplements.

Why Trust Verywell Fit

The product recommendations from Verywell Fit are purely editorial. We will occasionally receive products to test and review for free, but we purchase the overwhelming majority of the products we test. And while we do receive affiliate commission on some of the products we recommend, we never let retailers, public relations firms, or salespeople dictate our content and product coverage.

Before we test products, we read the latest studies on product safety and interviewing experts (including doctors, licensed therapists, registered dietitians, and more) for best practices, frequently asked questions, and the most important things to look for in a given product. Our writers and editors are also experts in their own right—for example, we have a certified running coach writing running content and designing our testing methodologies for running shoes; we have a stable of registered dietitians who write our nutrition and supplement content, all of which is overseen and published by a registered dietitian on our team.

Once written, every one of our articles is fact checked for accuracy and is vetted by a member of the Verywell Fit Review Board. However, you should consult your healthcare team to determine if a specific product—especially a food, supplement, or medical device—is right for you. Read more about our editorial process and our core values.

After we publish an article, we don’t just forget about it. Our team is relentless when it comes to updating and keeping our existing recommendations fresh, accurate, and helpful. We also know how frustrating it can be to do your research on a product only to add it to your cart and see that it’s out of stock, so we try to mitigate this by having dedicated editors check availability daily to provide you with the best user experience possible.
