Vitamin b 12 supplements is the least beneficial for people eating diets high in animal products.
The water-soluble vitamin cobalamin, often known as vitamin B12, is crucial for metabolism. It is one of the eight B vitamins. Animals require it because they use it as a cofactor in DNA synthesis and in the fatty acid and amino acid metabolism.
It is essential for the maturation of red blood cells in the bone marrow, which maintain the circulatory system, and the formation of myelin, which supports the neurological system. Since they don't need cobalamin, plants can carry out reactions with enzymes that don't require it.
Vitamin B12 is the most chemically complex vitamin and the only one that humans must consume in the form of food or supplements derived from animals. Almost no bacteria and archaea are capable of synthesizing vitamin B12.
