“It's a form of B12. The most popular form of B12, by the way, is one called cyanocobalamin. Does anyone know what that's made from? Hydrogen cyanide. Yes, it's legal in the United States to take the waste product from human sewage treatment plants called sludge, which is pure hydrogen cyanide, take that hydrogen cyanide, bind it to a metal called the cobalt metal, and make cyanocobalamin.”
“If you have genetic variants in the MTR or MTRR genes, your ability to convert cyanocobalamin is very compromised. You could be taking B12 every single day and still be functionally deficient.”
“It doesn't account for genetic polymorphisms that affect conversion efficiency. It means that you can be taking cyanocobalamin and have high serum B12, meaning high B12 in your blood, and still be functionally deficient in B12. Methylcobalamin skips the conversion step entirely.”
