What is Vitamin B12?

Vitamin B12, also known as cobalamin, is essential for numerous bodily functions. From producing red blood cells to DNA synthesis, supporting nerve health and energy production, this powerhouse vitamin is fundamental to your well-being.

What does B12 do?

Produces Red Blood Cells

Red Blood Cell Production: B12 supports the overall production of red blood cells in the bone marrow. By ensuring that the cells have the necessary components to divide and mature properly, B12 helps maintain a healthy balance of red blood cells in the bloodstream, which is essential for effective oxygen transport throughout the body.

Cell Division and Maturation: B12 is involved in the regulation of cell division and maturation. Specifically, it helps in the conversion of folate (another B vitamin) into its active form, which is necessary for the proper maturation of red blood cells. Inadequate B12 can disrupt this process, causing the red blood cells to remain immature and oversized—a condition known as megaloblastic anemia.

DNA Synthesis: B12 is essential for the synthesis of DNA, the genetic material in cells. Red blood cells are constantly being produced in the bone marrow, and proper DNA synthesis is necessary for the formation of new, healthy cells. Without adequate B12, the DNA synthesis process is impaired, leading to the production of larger, abnormal red blood cells that are less efficient at transporting oxygen.

Synthesizes DNA

Vitamin B12 supports DNA synthesis through its role in several biochemical processes essential for the production and maintenance of DNA.

Conversion of Homocysteine: B12 is involved in converting homocysteine, an amino acid, into methionine. This reaction is critical because methionine is a precursor to S-adenosylmethionine (SAMe), a compound that donates methyl groups necessary for DNA methylation—a process that regulates gene expression and DNA synthesis.

Formation of Nucleotides: B12 assists in the conversion of folate into its active form, tetrahydrofolate. Tetrahydrofolate is crucial for synthesizing nucleotides, the building blocks of DNA. Specifically, it helps produce thymidine, one of the key nucleotides required for DNA replication and repair.

Cell Division and Replication: During cell division, DNA must be replicated accurately. B12 supports this process by ensuring that the components required for DNA synthesis are available and functioning properly. This is particularly important in rapidly dividing cells, such as those in the bone marrow, which produce red blood cells.

Vitamin B12’s role in these biochemical pathways ensures that DNA is synthesized correctly and that cells can divide and function properly, supporting overall cellular health and proliferation.

Supports Nerve Health

One of its most critical functions is supporting the nervous system. B12 helps form the protective covering, called myelin, around your nerves, ensuring they function properly. It also contributes to the production of neurotransmitters, the chemical messengers that allow communication between your brain and the rest of the body.

Aids in Energy Production

Vitamin B12 supports energy production through several important mechanisms:

Metabolism of Fats and Proteins: B12 is essential for the metabolism of fats and proteins. It helps convert these macronutrients into energy by facilitating the breakdown of fatty acids and amino acids. This process occurs in the mitochondria, the energy-producing centers of cells, where B12 assists in the conversion of these substances into usable energy.

Conversion of Homocysteine: B12 helps convert homocysteine into methionine, a process that also involves the production of S-adenosylmethionine (SAMe). SAMe is crucial for several biochemical processes, including the synthesis of neurotransmitters and the regulation of energy metabolism.

Formation of Red Blood Cells: B12 is vital for the production of red blood cells. Healthy red blood cells are necessary for transporting oxygen throughout the body. Adequate oxygen delivery to tissues is essential for cellular energy production. Without sufficient B12, the body may experience reduced oxygen-carrying capacity, leading to fatigue and decreased energy levels.

INFORMATION

Who Needs B12?

B12 deficiencies are more common than you might think because B12 isn’t naturally produced by the body.  It must be obtained through diet or supplementation. B12 is primarily found in animal-based foods like meat, fish, eggs, and dairy. Once ingested, B12 is absorbed in the stomach with the help of a protein called intrinsic factor, which allows the vitamin to enter the bloodstream and reach the cells where it’s needed.
