Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a crucial role in various bodily functions. It is essential for maintaining good health and well-being. There are several forms of Vitamin B12, each with its own unique benefits.
Here are the four main types of Vitamin B12 and their associated health benefits:
- Methylcobalamin:
- This is the most bio-available type of Vitamin B12 which means the body absorbs it more easily. Naturally occurring, it is found in animal-based foods such as meat, fish, milk and eggs so Methylcobalamin B12 is readily available in many people’s daily diets. It is the most active form of Vitamin B12 and is used mainly in the liver, brain and nervous system.
- Cyanocobalamin:
- Is a synthetic form of Vitamin B12 which the body converts into Adenosylcobalamin and Methylcobalamin before it can be used. The most common and cost-effective form of Vitamin B12, Cyanocobalamin is most often found in supplements and some fortified foods.
- Hydroxocobalamin:
- Detoxification Support: Hydroxocobalamin is known for its ability to convert cyanide to less toxic substances in the body. This makes it useful in cases of cyanide poisoning and for individuals who have been exposed to high levels of cyanide, such as through smoke inhalation. It is also used for B12 supplementation.
- Adenosylcobalamin:
- Mitochondrial Function: Adenosylcobalamin is involved in the body’s energy metabolism at the cellular level. It supports the function of mitochondria, the cell’s powerhouses responsible for producing energy. This form of B12 is essential for overall cellular health and energy production.
