Printing Reports:

Members are welcome to print out reports for their individual use. To properly print, be sure to click on the "Print" icon in the upper right corner of the page. This will better position the printed report and avoid problems with printing scrollable tables. The pages are formatted to fit on most modern systems, but if the sides of the pages are being cut off on your print out, reduce the page to about 75% of the normal size. This can be done from your browser. Using Internet Explorer, for example, click File > Page Set Up > Printer > Properties and then click on an option to change printing effects in order to reduce the image size. Sometimes when printing from Internet Explorer a page will print blank. This is a problem unique to Internet Explorer. The easiest way around this is to print from a different browser, such as Firefox or Chrome.

Viewing Options

Narrow Screen
If your screen is too narrow to view the full width of a report, click the "Print" icon in the upper right corner of the report. This will provide a narrower version of the report, which should fit better within your screen. The Print option will also help if you like to enlarge web pages for easier reading, as you can enlarge the print version with less chance that text will move off the screen. Use the tools in your browser to enlarge ("Zoom In") the page.

Text Jumbled in Tables
If you have set your font size to larger than Medium in your web browser (e.g., Safari, Chrome, Edge, Firefox), the text in our tables may be too large and appear jumbled. To fix this, in your browser menu (sometimes indicated by 3 vertical dots), select Settings, look the Font Size option -- which may be under the category of Appearance, and choose Medium or smaller.

Tested Products:

We are continually testing products and posting new reports and updates. On a rotating basis we completely update the Product Review reports, testing a new group of products so that every popular report is updated approximately every two to four years. The products that we select for testing change with each report, allowing you to see results for a variety of current products. We publish the results for every product selected. If you no longer see a product listed in a report, it means that it was not selected for the most recent testing.

Before we conduct each Product Review, ConsumerLab members are asked by us (by email invitation) to suggest specific products that we should test, and we rely on these surveys, and results of previous tests, to guide our product selection. CL members are also welcome, at any time, to suggest products and product categories they would like to see tested. As our goal is to identify the best products, be aware that we are unlikely to select products that have failed previous tests or been negatively reviewed by us in the past. Keep in mind that there are over 1,000 brands of supplements sold in the U.S. and over 30,000 products and we can only test so many.

Companies are welcome to have their products tested through our Quality Certification Program. Products that pass testing in this program are added to the respective reports and are noted as having been tested through the certification program.

If you are a company whose product has failed testing in one of our reviews, you may obtain additional information at no cost, as described in our Policy Toward Manufacturers of Products that Fail to Pass CL Testing. For more information, contact
