Aside from being the popular ingredient in most multivitamin supplements, cyanocobalamin is mostly created using chemical synthesis. Cyanocobalamin is quite unique from all the other B12 varieties because it’s artificial and comes from the CN, or Cyano group.
To explain further, cyanocobalamin is created in laboratories. It’s simple- this form of B12 is the easiest and the cheapest to produce, and therefore is the most preferred compound. Companies who manufacture multivitamins and supplements buy the compound in bulk at a discounted price. This is certainly more appealing in a profit point of view as compared to the more expensive B12 types, like methylcobalamin for instance.
The only reason why it’s not dominating and outing methylcobalamin is that it has a precursor compound to the deadly cyanide. Generally though, B12 is added in minuscule quantities that getting poisoned is not a factor. Remarkably, our bodies do the work of converting cyano group vitamins such as cyanocobalamin into methylcobalamin in order for our system to make use of the available nutrient.
Granted, a small amount of cyanide gets released when your body starts converting cyanocobalamin to methylcobalamin, but as mentioned earlier, you wouldn’t need to strictly get the methylcobalamin version if you don’t suffer from severe kidney damage or if you’re not a smoker. The idea that you’re exposing yourself to a potentially poisonous precursor while taking health supplements is not a good thing. We expect to get the good stuff while consuming healthy supplemental products, right?
To put these queries to rest, it’s important to understand that cyanocobalamins will not introduce dangerous levels of cyanide in your system. Think of it like eating broccoli, which also contains trace amounts of cyanide. It’s perfectly fine to avoid this type of B12 source if you think otherwise.
