Treatment Of Vitamin B12 Deficiency

Vitamin B12 deficiency symptoms ( how to test for it and treat it with supplements)
  • Vitamin B12 supplements

  • For people with nerve damage, vitamin B12 given by injection

Older people with vitamin B12 deficiency benefit from taking vitamin B12 supplements because the deficiency usually results from difficulty absorbing the vitamin from meat. They can absorb the vitamin more easily from supplements than from meat.

Treatment of vitamin B12 deficiency or pernicious anemia consists of high doses of vitamin B12 supplements. If people have the deficiency but no symptoms, the vitamin may be taken by mouth. Blood tests are done periodically to make sure the vitamin B12 level returns to and remains normal.

People who have very low levels of vitamin B12 or symptoms due to nerve damage are usually given vitamin B12 by injection into a muscle. Injections, which may be self-administered, are given daily or weekly for several weeks until the vitamin B12 level returns to normal. Then injections are given once a month indefinitely, unless the disorder causing the deficiency can be corrected.

Anemia usually resolves in about 6 weeks. But if severe symptoms due to nerve damage last for months or years, they may become permanent. In most older people with vitamin B12 deficiency and dementia, mental function does not improve after treatment.

B12 Deficiency: Who Is At Risk

Most healthy adults get sufficient B12 from their regular diet. However, it is common for older people to have some level of B12 deficiency. This is often due to a poor diet and less stomach acid, which the body needs to absorb B12 from food.

Certain conditions and drugs also can interfere with absorption and increase your deficiency risk. For example, Crohn’s disease, pancreatic disease, diabetes, and heartburn medication, which reduces stomach acid. Vegans and vegetarians sometimes have trouble consuming enough B12 since many food sources are found in animal products like meat and dairy.

Low levels of B12 can cause fatigue, nervousness, dizziness, numbness, and tingling in the fingers and toes. Severe, long-term deficiency may lead to loss of mobility, problems walking, or memory loss.

A blood test from your doctor can measure B12 levels. A serious deficiency can be corrected with B12 shots or high-dose supplements.

What Are The Benefits Of Vitamin B12

Getting the correct amount of vitamin B12 each and every day may have the following benefits:

  • Contribute to energy yielding metabolism from food when its digested.

This Vitamin Deficiency Could Increase Your Risk Of Death From Covid

By this point, you’ve likely heard that vitamin D may be helpful in preventing adverse symptoms from COVID-19, as it’s known to support the immune system. However, there are several other vitamins and minerals that help strengthen immunity, one of which is known as cobalamin, or vitamin B12.

However, having a B12 deficiency right now can be a serious problem. In fact, it “may unknowingly increase the death rate of this pandemic, especially in older adults,” says Sally M. Pacholok, RN, BSN, an ER nurse who’s currently caring for COVID-19 patients, and the co-author of Could It Be B12? An Epidemic of Misdiagnoses.

A B12 deficiency is often misdiagnosed, yet the consequences of it can be fatalespecially for those who have contracted coronavirus and are already at high risk, Pacholok says. Inadequate B12 levels can suppress the immune system and inhibit the body’s ability to produce antibodies to viral infections. Severe deficiencies can even cause hyperhomocysteinemia, a condition that can cause fatal blood clots to form in the brain, lungs, and lower leg.

More people suffer from low vitamin B12 levels than you may think. In fact, Pacholok says that as many as 1 in 6 Americans are deficient. “B12 deficiency strikes all ages, races, and socioeconomic classes,” she says.

Food Sources Of Vitamin B12

Vitamin B12 is an essential water-soluble micronutrient of microbial origin . It is naturally found in animal food products, including meat, poultry, fish, eggs, milk, and other dairy products . Vitamin B12 is generally not present in plant foods, but fortified breakfast cereals are a readily available source of vitamin B12 with high bioavailability . Some nutritional yeast products also contain vitamin B12. This paper will only focus on vitamin B12 intake from natural food products, e.g. animal foods. According to recent results of the 2012-2016 Dutch Food Consumption Survey, the contribution of dairy, meat, fish, supplements, and eggs to total vitamin B12 intake is 38.5, 30, 8.5, 8.4, and 4.6%, respectively1. The nutrient dense animal food products rich in vitamin B12 are also rich in other nutrients such as zinc, iron, vitamin D, and proteins. To the best of our knowledge, interactions of vitamin B12 with these nutrients are not fully established, and it is not unlikely that associations of low vitamin B12 with health outcomes may be modified by deficiency of these nutrients or the presence of disorders that affect the digestive system. Notably, vitamin B12 and folate act together within the one-carbon metabolism, and paragraph 4.3.1 will elaborate on a potential role of high folate and low vitamin B12 status in health.

How Is It Treated

Usually, vitamin B12 deficiency anemia is easy to treat with diet and vitamin supplements. To increase the amount of vitamin B12 in your diet, eat more of foods that contain it, such as:

  • Beef, liver, and chicken
  • Low-fat milk, yogurt, and cheese
  • Eggs

Your doctor might recommend that you also take a vitamin B12 supplement. It comes in pills or a nasal spray. If you are very low in this vitamin, you can get higher-dose vitamin B12 shots. You may need to take vitamin B12 for the rest of your life. You might also need to get treated for the condition that causes your anemia.

But increasing your vitamin B12 levels is a key thing you can do. If you let it go for too long, it can damage your heart, brain, nerves, bones, and other organs in your body. With treatment, you should feel better and avoid any long-term problems.

Clinical deficiency can cause anaemia or nervous system damage. Most vegans consume enough B12 to avoid clinical deficiency. Two subgroups of vegans are at particular risk of B12 deficiency: long-term vegans who avoid common fortified foods and breastfed infants of vegan mothers whose own intake of B12 is low.

In adults typical deficiency symptoms include loss of energy, tingling, numbness, reduced sensitivity to pain or pressure, blurred vision, abnormal gait, sore tongue, poor memory, confusion, hallucinations and personality changes. Often these symptoms develop gradually over several months to a year before being recognised as being due to B12 deficiency and they are usually reversible on administration of B12. There is however no entirely consistent and reliable set of symptoms and there are cases of permanent damage in adults from B12 deficiency. If you suspect a problem then get a skilled diagnosis from a medical practitioner as each of these symptoms can also be caused by problems other than B12 deficiency.

Infants typically show more rapid onset of symptoms than adults. B12 deficiency may lead to loss of energy and appetite and failure to thrive. If not promptly corrected this can progress to coma or death. Again there is no entirely consistent pattern of symptoms. Infants are more vulnerable to permanent damage than adults. Some make a full recovery, but others show retarded development.
