Longevity Active Vitamin B12 Blood Test

$99.00

Vitamin B12, also known as cobalamin, exists in several forms. Among these forms, methylcobalamin and adenosylcobalamin are considered the active forms of vitamin B12. Methylcobalamin is involved in the methylation cycle, playing a role in processes such as DNA synthesis, amino acid metabolism, and neurotransmitter synthesis. Adenosylcobalamin, on the other hand, is a cofactor for enzymes involved in energy metabolism, particularly in the breakdown of certain amino acids and fatty acids.

These active forms of vitamin B12 are utilized by the body in various biochemical reactions and metabolic pathways. They are essential for overall health, including nervous system function, red blood cell formation, and energy metabolism.

When assessing vitamin B12 status, measuring levels of active B12 forms, particularly methylcobalamin and adenosylcobalamin, may provide a more accurate reflection of B12 status than total B12 levels alone. This is because total B12 levels may include inactive forms of B12, such as cyanocobalamin, which require conversion to active forms before they can be utilized by the body.
