What Function Does Vitamin B12 Serve in Health?

Vitamin B12 is a water-soluble nutrient important for blood cell production and the maintenance of nervous system health. It also helps prevent conditions like anemia.

Some people may have difficulty absorbing vitamin B12 from food, especially older adults or individuals with certain medical conditions. These include pernicious anemia, Crohn’s disease, or stomach diseases that reduce the absorption of this nutrient.

Nerve Function

One of the most important functions of vitamin B12 is to help with nerve function. When there is vitamin B12 deficiency, the nerves become damaged and this can lead to many different nerve diseases. Vitamin B12 helps to protect the nerves by blocking substances that have been shown in cell experiments to damage them. It also regulates levels of methylmalonic acid and homocysteine, two amino acids that have been shown to have direct neurotoxic properties.

Vitamin B12 is important for the formation and maintenance of the myelin sheaths, which are lipid-rich protective layers that cover the nerves. These sheaths function like the insulation around an electric cable, ensuring that the nerve signals are transmitted properly. Methylcobalamin has an important role in the production of these sheaths, while adenosylcobalamin plays a crucial part in regulating the synthesis of the fatty acids needed to make them.

Neurological symptoms associated with vitamin B12 deficiency can range from muscle wasting and weakness to psychiatric disorders. Symptoms of vitamin B12 deficiency can often be reversed by oral treatment, even without correcting the underlying cause of the problem. It is therefore very important to be sure that a B12 deficiency is not overlooked in patients over 40 years with neurological or psychiatric problems, especially those with a history of acid peptic disease. It is worth mentioning that the symptoms of vitamin B12 deficiency can occur completely independently of anaemia, so common blood tests can provide misleading results.

Blood Cells

Vitamin B12 helps make red blood cells, which carry oxygen throughout the body to support normal tissue function. It also aids in the production of DNA, which is the genetic material found in all cells. It contributes to our moods, brain health, and energy levels, and plays a role in the prevention of heart disease.

Your body doesn’t store vitamin B12, so it requires a regular supply from your diet or supplements. Because of this, a deficiency can lead to anemia – a condition where you don’t have enough healthy red blood cells. A deficiency can also cause neurological changes such as numbness and tingling in your hands and feet.

You can get vitamin B12 by eating foods that contain animal products or by taking a supplement. When consumed in food, vitamin B12 is bound to protein in a form called haptocorrin. In the stomach, digestive enzymes release the haptocorrin from vitamin B12 and combine it with intrinsic factor, a protein secreted by the gastric parietal cells. This complex is absorbed in the ileum of the small intestine.

People at higher risk for vitamin B12 deficiency include those who don’t eat much meat, including vegans and vegetarians, older adults, and individuals who take medications that interfere with absorption. Long-term use of metformin, a drug commonly prescribed for type 2 diabetes, has been associated with lower vitamin B12 and folic acid levels due to the medication’s ability to block absorption.

DNA Synthesis

Vitamin B12 (cyanocobalamin) is the only cobalt-containing vitamin with biological activity. The vitamin consists of an air-stable corrin ring containing the central metal ion in its +3 oxidation state. It is produced in the small intestine via bacterial metabolism from its precursors, hydroxycobalamin and methylcobalamin. It is also present in foods and nutritional supplements.

During DNA synthesis, the double-stranded structure of the chromosome is stabilized by specific pairing between adenine and thymine and between guanine and cytosine. The pairing is accomplished by the action of enzymes called DNA polymerases. DNA polymerases differ in their fidelity, or how reliably they produce DNA chains. For example, a DNA polymerase that fills short gaps in repair processes produces accurate chains at a much lower rate than one that synthesizes new DNA from scratch.

While the cellular DNA synthesis processes are highly reliable, mistakes do occasionally occur. These errors are corrected by a DNA repair system that involves excision of the damaged section followed by accurate resynthesis. A DNA polymerase like pol d can remove mismatched base pairs by removing the damaged strand and replacing it with the correct sequence.

Individuals with faulty digestive systems may be deficient in vitamin B12. A common cause of deficiency is a condition known as megaloblastic anemia, which results from interference with DNA synthesis and causes immature red blood cells that can’t carry oxygen. Deficiency of vitamin B12 or folate typically produces similar symptoms, including anemia and gastrointestinal problems.

Energy Production

There is a direct link between Vitamin B12 and energy because it works to help your body convert fat and protein into the fuel your cells need for energy. It’s also essential for making red blood cells that carry oxygen to your tissues, which helps you feel energized throughout the day. And it maintains myelin, a fatty nerve insulator that optimizes signaling from your brain to muscles, so your body can move as needed.

You can get Vitamin B12 from animal products like meat, fish, eggs, dairy products, and milk, or dietary supplements and fortified foods such as breakfast cereal. There is one synthetic form of Vitamin B12 called cyanocobalamin, which can also be found in some products, but it may not work as well in the human body as other forms of the nutrient.

Vitamin B12 deficiency is rare in the United States, but it can affect people of all ages and backgrounds. It’s especially common among vegans and people who follow other strict vegetarian diets, as well as pregnant women who might not absorb enough of the nutrients from their food. It’s also a risk factor for anemia, which can cause symptoms like fatigue, tingling sensations, and vision changes. The good news is, a B12 deficiency can be easily treated with injections or added to your diet.
