What is the central core of vitamin B12?
The structure of B12 is based on a corrin ring, which is similar to the porphyrin ring found in heme. The central metal ion is cobalt. As isolated as an air-stable solid and available commercially, cobalt in vitamin B12 (cyanocobalamin and other vitamers) is present in its +3 oxidation state.
What is the main source of vitamin B12?
Vitamin B12 is naturally found in animal products, including fish, meat, poultry, eggs, milk, and milk products. Vitamin B12 is generally not present in plant foods, but fortified breakfast cereals are a readily available source of vitamin B12 with high bioavailability for vegetarians [5,13-15].
Which essential element is a component of vitamin B12?
Vitamin B12, also known as cobalamin, comprises a number of forms including cyano-, methyl-, deoxyadenosyl- (coenzyme B12), and hydroxy-cobalamin. Note that the mineral cobalt is an essential part of the B12.
What is vitamin B12 made of?
Vitamin B12 supplements are typically derived from two sources: cyanocobalamin or methylcobalamin. Both are nearly identical and contain a cobalt ion surrounded by a corrin ring. However, each have a different molecule attached to the cobalt ion.
What is the best form of vitamin B12?
* Please note that cyanocobalamin is the form of B12 most used in supplements because it’s the cheapest and while we’ve presented methylcobalamin as the superior form both are excellent at providing nutritionally valuable quantities of Vitamin B12 to the body.
What is the function of B12 in your body?
Vitamin B12 is a nutrient that helps keep the body’s nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Vitamin B12 also helps prevent a type of anemia called megaloblastic anemia that makes people tired and weak. Two steps are required for the body to absorb vitamin B12 from food.
What happens when your vitamin B12 is low?
Not having enough B12 can lead to anemia, which means your body does not have enough red blood cells to do the job. This can make you feel weak and tired. Vitamin B12 deficiency can cause damage to your nerves and can affect memory and thinking.

What is the most common cause of vitamin B12 deficiency?
However, the most common cause of vitamin B-12 deficiency anemia is a lack of a substance called intrinsic factor, which can be caused when your immune system mistakenly attacks the stomach cells that produce this substance. This type of anemia is called pernicious anemia.
Which metal is present in vitamin B12?
Vitamin B12 is also referred to as cobalamin, because it contains a metal ion (cobalt). This makes it the largest and most complex vitamin of all. The vitamin can only be synthesized by bacteria and therefore is mainly present in animal products.
Who is at risk of B12 deficiency?
Vegans (people who don’t eat any meat, dairy, or eggs) are most at risk for developing a B12 deficiency because, aside from fortified breakfast cereals, the only reliable dietary sources of vitamin B12 are animal-derived products.

- Beef, liver, and chicken.
- Fish and shellfish such as trout, salmon, tuna fish, and clams.
- Fortified breakfast cereal.
- Low-fat milk, yogurt, and cheese.
Can you take too much B12?
Since B12 is a water-soluble vitamin, it’s generally considered safe, even at high doses. No Tolerable Upper Intake Level (UL) has been established for B12, due to its low level of toxicity. UL refers to the maximum daily dose of a vitamin unlikely to cause adverse side effects in the general population.
How do vegans get B12?
