Food and Drug Administration, March 23, 2016. “Best Bentonite Clay by Best Bentonite: FDA Alert – Risk of Lead Poisoning,” U.S. Susan Perry, “A Minnesotan’s Shopping Trip to Target sparks FDA warning about Bentonite Clay ‘Detox’ Product,” The MinnPost, February 3, 2016. It was so much so that machines could not get an accurate reading on the amounts of lead in a sample without requiring a controlled environment. It was created because there was so much lead everywhere (starting in the 1920’s). You know how scientists use clean rooms and biohazard suits? They are common when dealing with dangerous infections or delicate electronics.ĭid you know that the modern cleanroom was initially created to test lead? I prefer clean versions of fiber, especially those with resistant starch, like the Reset Shake and Ultra Fiber.Ĭombine either with chlorophyll from spinach or Daily Greens, and you’ll do a great job binding toxins and moving them out of your body without bringing more in. Gelatin, as found in bone broth, has been shown to pull lead out of cookware and raise the risk of lead toxicity. If you use bone broth, be especially careful about which cookware and utensils you use. The 2013 study claimed that bone broth was high in lead, yet the amounts they showed to be present are not considered to be significant. There is likely no safe amount of lead, but it is not possible to keep our total intake below a few ppb without eating or breathing. To convert ppb to ppm, one must multiply by 1000 therefore, 9.5 ppm = 9500 ppb. The bone broth study used mcg/L (aka μg/L), which is parts per billion (ppb). Above, I was talking about lead in terms of parts per million (mg/g). 23 This study created quite a bit of attention and worry. 22Īccording to a 2013 study, one batch of organic chicken bone broth contains 9.5 and 7.01 mcg/L of lead. 19 Bone Broth and Collagenīecause lead builds up in bone tissue 20 and collagen 21 in humans and other animals, bone broth and collagen products have been concerns as possible sources of lead contamination.Ĭows are especially prone to lead accumulation. These findings suggest that the lead in the fragments would likely also be absorbed by humans. The researchers fed venison with lead fragments to pigs and saw that the pigs’ blood lead levels elevated. When game is shot with lead bullets, the bullets break down into hundreds of tiny fragments that spread over a large area of the meat.Ī study found that 32% of packages of venison sampled contained fragments of lead. Inorganic calcium from rocks, such as dolomite calcium, can also have lead contamination. These include bone meal and microcrystalline hydroxyapatite complex. What are some other unexpected, possible sources of lead? Calcium SupplementsĬalcium supplements that are derived from bone tissue have often been found to have high levels of lead. In fact, they argued that “lead that is naturally present in many foods and clays just are not available to the body.” 3 It turned out that the manufacturer of one of these products rejected these warnings. The FDA verified the results and went on to find similar problems with other bentonite products they tested. Is bentonite clay safe to ingest? In this case, sure enough, the product in question had unsafe levels of lead. She bought the clay and sent it to a lab for analysis. She remembered that the family she was working with had been taking bentonite clay in hopes of detoxifying. Curran de Nieto was shopping in a nearby Target store when she noticed a product, called “Bentonite Me Baby”. Despite avoiding typical lead sources, they did not seem to be coming down. She’s a fellow Minnesotan who was struggling to lower the blood lead levels of a local family. Recently, I heard a story about Megan Curran de Nieto. ![]()
