B12 is Cyanocobalamin
Posted by 4893910986728011477 on Mar 31, 2016
Cyanocobalamin is a cheap, synthetic chemical made in a laboratory. It's virtually impossible for you to find this form in nature. Low-end vitamin manufacturers use it because it can be bought in bulk and added to products with claims that they "contain vitamin B-12!" What they don't tell you is that the vitamin is bound to a toxic, poisonous cyanide molecule that must then be removed from your body by your liver. Cyanocobalamin is also up to 100 times cheaper than the higher quality methylcobalamin which we'll talk about below.
