You may have noticed warning panels on Redmond Clay and other products, like Earthpaste, that contain Redmond Clay. Our clay hasn’t changed since nature made it a long, long time ago. To learn more about prop 65 visit:
⚠️ WARNING: Cancer and Reproductive Harm - https://www.p65warnings.ca.gov/
Natural bentonite clay is the base of a lot of Redmond Life products (including Earthpaste). Since this clay is from the earth, it contains trace amounts of earth-based elements, including lead. Because of this, the state of California requires that we put a Prop 65 statement on the product that says it may not be appropriate for some women and children.
When it comes to elements and the body, the FORM of the element is key. Studies show bentonite clay is structured in such a way that it is not absorbed by the body. According to an FDA funded study, "Apparently, very little, if any, bentonite is absorbed after oral administration and as much as 3 percent in the diet has no observable adverse effects on experimental animals . . . No adverse effects have been observed at dietary levels as high as 12 percent in experimental animals. The human therapeutic dose for diarrhea is about 250 to 1,000 mg per kg.”
Note: Natural dentists also use clay to remove mercury after amalgam extractions: http://www.winaturaldentist.com/amalgam_safety.asp
There are also studies showing that bentonite/montmorillonite clay has been found to "significantly reduce lead concentration of tissues in blood, brain, liver, bone, kidney and hair." For example, http://www.ncbi.nlm.nih.gov/pubmed/18568297 is a full peer-reviewed study published by PubMed (United States National Library of Medicine Search Engine).
Additionally, there are many other PubMed studies you might be interested in showing this type of clay's ability to remove toxins such as lead, cadmium, aflatoxin, and others from the body. This is why many concerned with lead and other environmental toxins seek out bentonite/montmorillonite clay and clay-containing products, even though in nature there is a small amount that is bound tightly to the clay.
We are not saying that clay or clay-based products are right for everyone, just that there are many peer-reviewed studies on the potential benefits of clay. We don't want anyone to use any of our products if they don't feel good about using them. Clays have been used by humans and animals since the beginning, and continue to be studied for a variety of human and animal uses.
