Back to the toothpaste conversation.
Food (and water) is considered toxic for lead in the “Parts Per Billion” (ppb) ranges. Specifically water and food are considered toxic (by many in the scientific community) at levels starting at FIVE parts per billion and higher (some use the less protective federal level for water toxicity of 15 parts per billion lead or the even less strict outdated threshold of 20 parts per billion lead to determine lead toxicity in items intended to be interested daily by humans.)
Regardless of the nuances of how many (single or double-digit) parts per billion lead is toxic in items ingested daily by humans… the Earthpaste bentonite Redmond Clay has tested positive (using an XRF) in the range of 11 to 15 parts per MILLION (ppm) not parts per BILLION (ppb).
This amount of lead in an item intended for human consumption is not considered “trace” it is considered highly toxic. (This level would only be considered “trace” lead, for example, if this was the level of lead found in a consumer good – like pottery.)
Earthpaste (the company) has a white paper confirming they have found lead levels in this range (here is their analysis confirming 11.9 ppm lead in the clay that is the base for their toothpaste.) I also personally found/ reconfirmed lead in this same range using an XRF on their clay base.
Most food-items are so low in lead that they will not test positive for lead with an XRF.
Said another way, I personally have never tested another food item, spice, or other type of food ingredient (or item intended for oral use / human consumption – including chocolate) that was high enough in lead to test positive using an XRF.
The bentonite clay is the only ingredient like this (intended for ingestion/oral use/ human consumption) that I have tested with an XRF that was positive at detectible levels for lead (using an XRF.) This is very concerning.
Here is a little graphic from an online number translator translating PPM (parts per million) to PPB (parts per billion.) Even taking the low end of what I found (11 ppm) Earthpaste is positive for 11,000 parts per BILLION lead, when the toxicity level in food has been determined to be in the 5 to 15 parts per billion range.
Seriously reconsider using toothpaste that:
1) has tested positive for lead,
2) already has a warning for lead and
3) is admitted by the company to have lead.
The allegation that it (the lead found in toothpaste made with bentonite clay) is not bioavailable is also untrue. All lead in all of its forms is bioavailable to some degree. Said another way, each type of lead has some percentage that is bioavailable. There is no form of lead that is 100% not bioavailable. Do you want to be the guinea pig to find out how bioavailable the lead you are ingesting is? I think not.
Here’s my #SaferChoices toothpaste post too.
