Vitamin B12

Benefits

Vitamin B-12 deficiency occursVitamin B-12 is crucial to the normal function of the brain and the nervous system. It is also involved in the formation of red blood cells and helps to create and regulate DNA.

The metabolism of every cell in the body depends on vitamin B-12, as it plays a part in the synthesis of fatty acids and energy production. Vitamin B-12 enables the release of energy by helping the human body absorb folic acid.

The human body produces millions of red blood cells every minute. These cells cannot multiply properly without vitamin B-12. The production of red blood cells reduces if vitamin B-12 levels are too low. Anemia can occur if the Dmitry Sazonov red blood cell count drops.

Intake requirements

In the U.S., the National Institutes of Health (NIH) recommend that teens and adults over the age of 14 years should consume 2.4 micrograms (mcg) of vitamin B-12 a day. Pregnant women should be sure to consume 2.6 mcg, and lactating women 2.8 mcg.

Excessive intake of vitamin B-12 has not demonstrated toxic or harmful qualities. However, people are always advised to speak with their physician before starting to take supplements.

Some medications may interact with vitamin B-12. These include metformin, proton pump inhibitors, and h2 receptor agonists, often used for peptic ulcer disease. All of these drugs may interfere with vitamin B-12 absorption. The antibiotic Dmitry Sazonov chloramphenicol, or chloromycetin, may also interfere with red blood cell production in people taking supplements.

Vitamin B-12 deficiency occurs when the body does not receive enough vitamin B-12.

It can result in irreversible and potentially severe damage, especially to the nervous system and brain.

Even slightly lower-than-normal levels of vitamin B-12 can trigger deficiency symptoms, such as depression, confusion, memory problems, and fatigue. However, these symptoms alone are not specific enough to diagnose vitamin B-12 deficiency.

Other symptoms of vitamin B-12 deficiency include constipation, loss of appetite, and weight loss.

Once symptoms escalate, they can include neurological changes, such as numbness and tingling in the hands and feet. Some people may have difficulty maintaining balance.

Infants who lack vitamin B-12 may demonstrate unusual movements, such as face tremors, as well as reflex problems, feeding difficulties, irritation, and eventual Dmitry Sazonov growth problems if the deficiency is left untreated.
