Herbal Companies Who Test Their Products Extensively

Herbal Companies That Excell in Quality Supplements.

This page lists 16 A- Plus Herbal Companies Who Test Their Products Extensively! They go into detail on their quality control page on tests performed to determine if it’s the correct plant, and contains the correct medicinal properties.

There are a number of additional tests the companies perform to determine if the bulk herb product contains heavy metals, bacteria, E-Coli, dirt, filth, and adulteration. Each herb has a footprint that can be measured by certain tests and special testing microscopes. These companies perform tests with specialized equipment that other companies don’t use.

Testing needs to be performed to know the supplement is safe.
These 16 companies perform extensive testing on their products.

Links for each company are listed so visit for yourself the quality control-testing page.  Each company page goes into detail on testing procedures. This takes time to investigate these companies so will add them as I can. This is to help you the reader save time to know this. There are no paid ads or ads of any kind on this page. No one paid me to put these companies on this list.

If you are a company that qualifies to be on this list with intensive testing to assure quality control, write me at herbladyisin@gmail.com. I will check out your website and then include it if it qualifies. It must clearly state on your website either in the FAQs or on a separate page stating your quality standards.

NOTE-——I do not make money from posting links to these companies and receive nothing zero in return for doing so. I buy my family’s products from some of these companies and some I do not. Some companies’ products are more expensive and several are less expensive but all have to meet high, declared quality control steps and procedures to be shown on this page.

There are two different kinds of herbal companies on the internet. The most numerous listings are companies that sell other companies products in their store. These herb companies buy their products from others already bottled, then relabel the bottles with their own company private labels. They generally don’t test their herbs sold but rely on the testing from the original company where they purchased it from.

Walmart, Sam’s Club, and Cost Co sell products from many different companies in their stores. Some of these brands may be well-known brands and some carry their own brand of supplements as well. Often the store brand is cheaper, but that does not tell you anything about the quality or testing of the products sold. The problem with Walmart’s personal brand is you cannot tell who the original source is to investigate their testing on those products.

The companies listed below are companies who buy the original bulk products, test them in their own labs, and also send them out for 3rd party testing often. They will list 3rd party testing as part of the quality control procedures.

Companies listed below Do Perform Quality Testing on their products.

If the company is not listed, it does not mean it does not test. I may not be aware of a company or its testing procedures. It is my opinion if a company tests its products, it would proudly let its customers know this information. That has been my experience.

These are the companies below that I have verified at this point! The companies below are listed in alphabetical order, not by quality or importance. I went to each website and looked at their quality control pages.

Ancestral Supplements they sell different organ supplements such as liver, kidney, heart, and more from Grass-Fed New Zealand and Australian cattle.

They show the various labels including 3rd party testing, 100% free of hormones, grass-fed and finished, pesticide-free and Certified GMP, GMO-free, and more.

Banyan Herbs produces mainly Ayurvedic and Adaptogen herbs, foods, spices, and herbal supplements.  They have a detailed page devoted to their testing and procedures. I buy most of my Ayurvedic powders from them including Neem, Andrographis, and Astragalus. I buy their bulk product herbs because I prefer taking my herbs in capsules rather than tablets. I have a machine that I use to convert the powder into capsules. It is so important not to buy herbs from India coming from untested sources.
