B12 supplements are fake B12, not the real B12 naturally found in meat! The most common type of B12 in supplements is cyanocobalamin which is a synthetic chemical! Cyanocobalamin is made with cyanide! The best and most natural form of B12 for humans is cobalamin, it is naturally found in meat and most animal based food products. B12 cobalamin together with animal iron (heme iron) is the best combnination.
Nature designed humans to eat meat, not take fake B12 pills or fake B12 injections.
Vitamin B12 is also called cobalamin, is a water-soluble vitamin that contains a mineral called cobalt, with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins. It is normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid metabolism and amino acid metabolism.
Deficiency of B12 lead to many kinds of illnesses and even death. Although human requirement for B12 is very low but most vegans are deficient in it, that's one of the reasons most vegans have serious mental illness and many other health problems such as anemia and heart disease, some to the point that caused their deaths.
