Vitamin B12 works together with folate in the synthesis of DNA and red blood cells. It’s also involved in the production of the myelin sheath around the nerves, and the conduction of nerve impulses. You can think of the brain and the nervous system as a big tangle of wires. Myelin is the insulation that protects those wires and helps them to conduct messages.
Vitamin B12 is fittingly known as the energy vitamin, and your body requires it for a number of vital functions. Among them: energy production, blood formation, DNA synthesis, and myelin formation. Myelin is insulation that protects your nerve endings and allows them to communicate with one another.
Facts about vitamin B12
- As many as 30% of adults over 50 are unable to absorb B12 in food, making supplementation the best source.
- Vitamin B12 deficiency may lead to brain shrinkage.
- There is a link between vitamin B12 deficiency and Alzheimer’s disease.
- Vitamin B12 deficiency leads to megaloblastic anemia, a fatigue ridden condition where red blood cells don’t develop properly and can’t carry oxygen efficiently.
Causes of B12 malabsorption include
- intestinal dysbiosis
- leaky gut and/or gut inflammation (Crohn´s disease, Ulcerative colitis, bacterial growth or a parasite)
- atrophic gastrits or hypochlorhydria (low stomach acid)
- pernicious anemia (autoimmune condition)
- medications (especially PPIs and other acid-suppressing drugs)
- exposure to nitrous oxide (during surgery or recreational use)
B12 is the only vitamin that contains a trace element (cobalt), which is why it’s called cobalamin. Cobalamin is produced in the gut of animals. It’s the only vitamin we can’t obtain from plants or sunlight. Plants don’t need B12 so they don’t store it.
