What does vitamin B12 do in the body?
Vitamin B12 is involved in red blood cell formation, DNA synthesis, and neurologic function. It acts as a cofactor in metabolic pathways that convert nutrients into usable cellular energy, which is why even small deficiencies can affect multiple systems at once.
What happens when B12 is suboptimal?
Energy production and nerve signaling can become less efficient, which may show up as fatigue, reduced focus, or changes in mental clarity.
How does B12 affect the nervous system?
It supports the maintenance of the myelin sheath, which protects nerve fibers and allows efficient signal transmission between cells.
Why can B12 levels be low even with a good diet?
Absorption depends on the intrinsic factor and proper gastrointestinal function. Conditions affecting the stomach or small intestine, as well as certain medications, can reduce how much B12 is actually absorbed.
