Vitamin B12: Benefits, Sources, and Deficiency

Vitamin B12: Benefits, Sources, and Deficiency

 

Introduction

B12 or cobalamin is a vitamin that is vital and has numerous functions in the body. It aids nerve health, the production of red blood cells, DNA production and energy. Vitamin B12 cannot be synthesized in the human body and therefore needs to be consumed in the form of foods or supplements.

This paper discusses the possible advantages of Vitamin B12, food sources of the vitamin, signs of deficiency, and those who are at risk. The information is intended to be of general interest and is not to be taken as any form of medical advice. Do not alter what you are eating or adding supplements without the advice of your health care provider.

 

What Is Vitamin B12?

Vitamin B12 is a water-soluble vitamin, which is part of the B-complex vitamin. It is also found naturally in animal products and can be incorporated in foods that are fortified or utilized as a supplement. The effects of deficiency in the B12 vitamin may take several years to show themselves, unlike other water-soluble vitamins which are stored in the liver to some degree.

 

Key Functions of Vitamin B12

·       Helps with red blood cell production and will prevent anemia

·       Supports health of nerves system.

·       Aids in DNA creation

·       Aids in conversion of food into energy

·       Stimulates the brain power and cognitive capacity

 

Potential Benefits of Vitamin B12

Although Vitamin B12 is important to overall health, it should be noted that all these benefits are on general nutritional functions and not on medical claims.

1. Supports Red Blood Cell Formation

Vitamin B12 is also required to manufacture healthy red blood cells. Its lack may lead to megaloblastic anemia, in which red cells are overgrown and ineffective, which leads to fatigue and the inability to cope with work.

2. Promotes Nerve Health

B12 is useful in protecting the cover of nerves (myelin sheath). Sufficient amounts can promote appropriate nerve signaling and minimize the occurrence of nerve-related discomfort.

3. May Boost Energy Levels

As B12 is involved in food into energy conversion, people report increased energy levels when the deficiency is corrected. Nevertheless, intake above certain levels cannot bring energy to those who have adequate levels.

4. Supports Brain Function

According to some research, it is possible that healthy cognitive performance in older age could be linked to sufficient levels of B12. But further studies must be done in this direction.

5. May Help with Mood Regulation

Vitamin B12 helps with the synthesis of serotonin which is a neurotransmitter that affects mood. Mood changes may be experienced by some persons with low levels of B12 but only when supplementation is done with the guidance of a physician.

6. Supports Heart Health

B12 collaborates with folate and Vitamin B6 to control the level of homocysteine. High homocysteine is linked with cardiovascular disorders yet more research needs to be done to determine direct correlation with B12.

 

Sources of Vitamin B12

Vitamin B12 is not produced by the body, so it has to be included either in food or in supplements. The following are some of the best natural and fortified sources:

Animal-Based Sources

·       Beef, liver and chicken

·       Salmon, trout, tuna and sardines

·       Shellfish like mussels, oysters and clams.

·       Milk, cheese and yogurt are dairy products

·       Eggs: In particular, the yolk

Fortified Foods (For Vegetarians and Vegans)

·       Fortified cereals

·       Almond, soy, oat cow milk

·       Nutritional yeast

·       Fortified tofu

 

Supplements

Supplements are also in different forms in case a person has a hard time consuming enough B12 in food:

·       Cyanocobalamin: is man made and found in supplements

·       Methyl cobalamin: It is a naturally derived one, which is easily absorbed

·       Sublingual tablets or sprays: An alternative to those that have problems with absorption

Before adopting any form of supplements, it is always important to consult a healthcare expert.

Vitamin B12 Deficiency: Causes and Symptoms

Vitamin B12 deficiency is a widespread problem, mainly in older people, vegetarians, and patients with some medical conditions. Symptoms appear gradually, and thus they are unnoticed.

Common Causes of Deficiency

·       Dietary Deficiency: Vegans and vegetarians that do not take fortified foods or supplements

·       Malabsorption Problems: Malabsorption problems can include pernicious anemia, celiac disease or Crohn disease

·       Age-Related Deterioration: Older people have reduced stomach acid production and this prevents B12 absorption

·       Drugs: Constant taking of ant-acidic medicine (e.g proton pump medications)

·       Gastric Surgery: Therapies such as weight loss surgery may have an impact on absorption

Signs and Symptoms of Deficiency

·       Fatigue and debilitation

·       Pallor or jaundice of the skin

·       Pins and needles (numbness or tingling) in the hands and feet (peripheral neuropathy)

·       Trouble with, unless there is a balance problem

·       Amnesia or confusion

·       Glossitis (enlargement, inflammation of the tongue)

The extreme or chronic deficiency may result in neurological complications and therefore early detection is essential.

Who Is at Risk of Vitamin B12 Deficiency?

There are some groups of people who are at an increased risk of having B12 deficiencies and may need to be monitored or supplemented:

1. Older Adults

As a person ages, there is less stomach acid, which is required to absorb B12. Low levels of B12 can be present in up to 20 percent of the older adults.

2. Vegans and Vegetarians

People who eat only plant-based foods should depend on fortified foods or supplements since B12 is mostly available in animal food.

3. Individuals with Digestive Disorders

The diseases that cause an impairment in the absorption of nutrients can be celiac disease, Crohn diseases, or atrophic gastritis.

4. People Taking Certain Medications

Long term intake of metformin (used in treatment of diabetes) or acid-reducing medication may affect B12 absorption.

5. Those Who Have Had Gastric Surgery

Surgeries or stomach resections used in weight loss can lower the intrinsic factor, which is a protein required to absorb B12.

Diagnosis and Treatment of B12 Deficiency

In case of suspected deficiency, a healthcare provider may prescribe:

Diagnostic Tests

·       Serum B12 Test: It determines the levels of B12 in the blood (but this does not always reflect the level in the tissue)

·       Methylmalonic Acid (MMA) Test: it is a more sensitive test to determine the status of B12

·       Homocysteine Test: A test such as this can give a sign of deficiency

Treatment Options

·       Change in Diet: Eating more of the foods which contain B12

·       Oral Supplements: B12 in high doses in the form of tablets in mild deficiency

·       Injections: When prescribed, injections are used in severe cases of deficiencies or problems with absorption

The duration of such treatment depends on the cause and severity of the deficiency.

Preventing Vitamin B12 Deficiency

Healthy B12 Levels:

·       Regular consumption of animal foods or foods that have been fortified.

·       Supplements can be considered where intake of the diet is not enough (under medical supervision).

·       Get routine check-ups in case you belong to a risky group.

 

Conclusion

Vitamin B12 is a vital nutrient and it helps in the production of red blood cells, nerve health, and energy production. Deficiency is common but, in most cases, can be prevented or treated by changes in diet or supplementation. Older people, vegans, and people with digestive issues belong to those who should pay more attention to their B12 intake.

Before drastically changing your diet and before commencing taking new supplements, it is always advisable to seek the advice of a healthcare expert. Proper diagnosis and treatment would aid in optimal health and wellbeing.
