Testing PrimalLife Premium Dirty Mouth Powdered Mineral Toothpaste (Fluoride-free, in Polished Peppermint Flavor) for Lead, Cadmium, Mercury, & Arsenic with Independent (Community-Funded), Third-Party Laboratory Testing

| | | | | | | | |


  


Published May 28, 2025 — Wednesday
A Quick Note from Tamara Rubin:

As anticipated, this PrimalLife Premium Dirty Mouth Powdered Mineral Toothpaste is incredibly toxic and is illegal by the new (January 2025) Washington State Standards. The new Washington standard limits the amount of Lead in cosmetics and personal care products to one part per million (1 ppm is the same as 1,000 parts per billion). Fluoride-free toothpaste is classified as a cosmetic product.

This is the second product from this brand that we have sent to the lab for testing — here’s a link to the first one. We sent this in for laboratory testing so we could have more evidence in our reports to Washington State and the FDA supporting the fact that the toxicity concern with this brand is not “batch specific,” or “product specific “(the concern applies to all PrimalLife tooth powders, regardless of the flavor or packaging). Here’s a link containing all of our articles related to this brand.

There is a real (non-zero) risk that chronic/ persistent low-level Lead poisoning could be caused by this product, especially given the company encourages swallowing (or does not discourage it, depending on which literature/ marketing/ advertising you come across).

As all relevant federal agencies agree that there is no safe level of Lead exposure for human beings, I would strongly recommend against using this product. You may also want to consider getting (immediately) tested for heavy metals if you have been using this product on a regular basis — ask your doctor. This article (linked here) is a useful read before getting tested. You may also find this article helpful.

If you would like to join us in reporting this product (and brand) to the FDA, here’s the link to do so (please include your child’s test results, or your own, if the person using this product has tested positive for Lead): https://www.fda.gov/safety/report-problem-fda

The safer toothpaste I have chosen for my family in response to testing we have conducted (a mint toothpaste that tested non-detect for Lead, Mercury, Cadmium, and Arsenic through the Lead Safe Mama, LLC Community Collaborative Laboratory Testing Initiative) can be found at this link: https://amzn.to/3HrM7cc  there are five additional toothpaste options on our “safer choices” list below (scroll down).

Click through this landing page for more products we have tested, organized by category. To see the original lab report for this product, scroll down to the bottom of the page (again, the report is below the shareable social media graphic summarizing the test results). Our lab-tested safer choices list is below as well.  To see  our toothpaste comparison chart with results for most of the toothpastes (and tooth powders) we have tested and reported on to date, click here (and stay tuned, this chart will be updated shortly).

As far as safer choices for foods, supplements, and cosmetics go (including toothpastes and other personal care products), we have a few lists on our laboratory testing landing page (linked here) that you may find to be helpful in making safer choices for your family. We even have one dedicated to safer snack choices, here

Here’s the link to our landing page with ALL of the lab reports for the independent, third-party laboratory testing Lead Safe Mama, LLC has coordinated since March 2024 — this is also a good page to bookmark and check back on periodically (it is always pinned at the top of the website’s Menu via the button graphic below, and the Menu can be found at the top of every page on this site).

Please check out our open/ not-yet-funded campaigns on GoFundMe if you would like to support some of our additional independent, crowd-funded, third-party laboratory testing. Thank you!

Are you interested in seeing MORE safer choices?

Below is an expanding list of products (foods, supplements, cosmetics, and personal care items) that tested “non-detect” for Lead, Mercury, Cadmium, and Arsenic with independent, third-party, community-funded laboratory testing coordinated by Lead Safe Mama, LLC (an Oregon-based small business with a unique community-collaborative business model and a focus on consumer goods safety and childhood Lead poisoning prevention). The product examples below clearly demonstrate that companies can manufacture safer choices (at least from the perspective of a concern for heavy metals contamination).

The limits of detection (low-threshold of detection) for each of the metals tested are noted in the lab report for the specific product listed. To see the full original lab report for any of these products, type the brand name into the search bar at the top of any page on Lead Safe Mama dot com (and scroll down to the bottom of the related article). All our published lab reports are also linked here, on our lab testing landing page.

Flavors (or specific variations) tested are noted, and other flavors of the same product (or other products from the same brand) have either not been tested or have been tested but did not yield similar results. Test results only apply to the specific products linked below.

Products on our “safer choices” list are re-tested periodically (annually or more frequently, as funding permits). If a product no longer tests clean, it is removed from the list.
