  • Thank you very much for doing the math! That really does put it into perspective.

    I was assuming you would still be absorbing the lead through your gum line and sublingually through the glands under your tongue into your bloodstream even without swallowing any, but that does sound like extremely low quantities.

    For me personally, I have ADHD and a bad memory so anything I can do to mitigate exposure to lead to lessen my chance of developing Alzheimer’s or Dementia as I get older seemed like an obvious decision especially when the solution is to just get a low abrasion toothpaste that doesn’t include these potentially contaminated abrasive materials.



  • For what it’s worth, the toothpastes that only used calcium carbonate had quite low levels of lead. It seemed to be the ones that use bentonite clay that have ridiculously high levels of lead and that is the far more concerning ingredient which was not present in OP’s photo


  • Yeah that’s pretty much exactly what I’m saying. I just didn’t really feel like typing it all out. Yes the claim there is effectively all chalk is contaminated with lead based on all of the different XRF results she’s done on toothpaste.

    Kind of like how basically all cocoa beans are contaminated with lead and cadmium as shown by consumer reports. The beans themselves do not contain lead, but the countries that harvest the beans just throw them on the ground and the ground is contaminated with lead and the dust gets on the beans and makes its way into our dark chocolate.

    I have bad news about the first ingredient, calcium carbonate. It contains lead!

    Edited for clarity: it is derived from chalk as the toothpaste explains and effectively all chalk on Earth is contaminated with lead as shown in the article below, which uses x-ray fluorescence to confirm the presence of lead, cadmium, mercury, arsenic.

    In general, you want to avoid the following ingredients in your toothpaste if you are trying to minimize lead exposure:

    • Bentonite Clay
    • Hydroxyapatite
    • Calcium Carbonate
    • Hydrated Silica
    • Titanium Dioxide
