In May 2018, Nickel and Boron were removed from the vitamin/mineral formulation of Keto Chow, you’ll find this change on the “Keto Chow Change Log” where we publicly list what we’ve changed in each revision of Keto Chow – the short explanation of why it still shows on the ingredients is: there is a chance people could get one of the old bags somehow and we would rather lose a potential customer than accidentally making someone ill that is legitimately allergic to nickel.
Nickel and Boron both *might* be necessary for good health (see https://www.ncbi.nlm.nih.gov/books/NBK222322/#ddd00690) but there are no clear results that can be looked at for absolute certainty. There are, however, people that are allergic to Nickel, and Boron presents problems as well; so the ultimate decision was to remove both. Because of the potential for allergies, Nickel was left on the Keto Chow ingredients page until ALL of the product we have on-hand has switched to 2.1.2+ we feel it’s better that people who are intellectually sensitive to the presence of Nickel avoid Keto Chow when it doesn’t actually have it, rather than risking someone that is actually sensitive to Nickel being exposed.
We take it very seriously what goes into Keto Chow and work very hard to make sure that we have the best stuff possible (see https://www.youtube.com/watch?v=2dVKZqYKPxk ). So seriously that the founder of Keto Chow decided to live exclusively on Keto Chow for 100 days, 3 meals a day, mostly to prove a point – when the person formulating a product decides to live on it for several months, you’ll find that any potential problems go away really quickly. Honestly, we wish more companies would try something similar.
As for other heavy metals, we’ve had Keto Chow tested for those too and even posted the results so you can see them for yourself. It’s interesting to note that the flavors containing plant-derived flavors and spices (cinnamon, cocoa, etc…) have the highest levels of heavy metals (though the levels are still insanely low). If you’re concerned about heavy metal exposure, apparently eating plant foods is what you would want to avoid, which would probably surprise those advocating that type of eating pattern.
