When and how should they be supplemented?

Vitamin B12, or cobalamin, is a water-soluble vitamin that is solubilized in water, as its name implies. It is only partially accumulated in the body. Consequently, it is necessary to consume it on a consistent basis through food.

This may be familiar to individuals who adhere to or aspire to a vegan or vegetarian diet, as these diets frequently necessitate particular supplements.

Dr. Martina Anderson, a nutritionist at H. Medical Care, provides us with information on the purpose of B12 and the location where it can be obtained.

B12: What is its purpose?

Vitamin B12 plays a variety of functions that are essential for the optimal functioning of the body. In particular, it is essential for the metabolism of fatty acids, nucleic acids, and amino acids. In conjunction with folic acid, it aids in the synthesis of DNA and RNA. It is also crucial for the production of red blood cells and the development of bone marrow. And, it also facilitates the conversion of nutrients into energy and alleviates tension by elevating mood.

The diet

B12 is present in foods of animal origin in an enzymatic form, which is linked to proteins. It is made accessible through the action of certain gastric enzymes. It is particularly evident in:

meat; fish; liver; milk; egg;

In comparison to the amount of B12 present in foods, the quantity absorbed is 60% for meat and milk, 30-40% for fish products, and, according to certain studies, less than 10% for eggs. Additionally, approximately one-third of the vitamin is lost during the preparation process.

The daily requirement for adults is typically consumed in conjunction with a typical diet and is equivalent to approximately 2-2.4 mcg. Nevertheless, expectant or breastfeeding women must consume a greater quantity to ensure that the fetus receives the appropriate amount.

What is the result?

This type of deficiency can manifest in individuals who adhere to a vegan diet or when the absorption mechanism malfunctions in the intestine. It is challenging for individuals who consume a diverse and balanced diet to detect any deficiencies.

The causes of malabsorption can include inflammatory diseases, malabsorption diseases (e.g. celiac disease), drugs, the proliferation of microbes, a decrease in gastric acidity, particularly in the elderly, or the absence of the intrinsic factor, which is responsible for absorption.

The deficiency is associated with the absence of foods of animal origin that contain it in vegan diets.

A form of anemia known as “pernicious” is the primary repercussion of deficiency. This condition is caused by inadequate blood cell production and can manifest as fatigue, lethargy, pallor, and tingling in the extremities. The nervous system may also be affected in more severe cases.

The diagnosis is determined through laboratory tests. If a deficiency is suspected, the blood B12 level is assessed, and the red cell size is monitored to prevent it from exceeding a certain threshold.

In order to prevent detrimental effects on the expectant child, pregnant women should refrain from developing deficiencies.

Vegan Diets

At present, there are no processed plant foods that can meet the vitamin B12 requirements of humans.

Brewer’s yeast, certain algae, and certain foods of oriental origin, including tempeh (derived from soybeans) and Kombucha (Chinese tea), contain vitamin B12. However, these substances are insufficiently concentrated to meet human requirements due to their inability to be assimilated by the humans.

In light of this, individuals who consume exclusively plant-based diets must obtain this vitamin through specific supplements. Consuming fortified foods, which are foods that have been supplemented with B12, can also be beneficial. It is crucial to initiate supplementation immediately following birth in order to prevent deficiency, even in infants of vegan mothers.

How does this relate to protein?

The vitamin C complex, folates, and B12 are essential for the production of proteins in the body. Additionally, it is important to note that stomach acid is responsible for the absorption of B12 by our body. This acid separates B12 from the proteins found in food and attaches it to another molecule, thereby facilitating its absorption.

The metabolic process is significantly influenced by B12. The nervous system’s integrity is safeguarded by promoting the production of red cells and facilitating protein metabolism.What are the symptoms and the underlying causes?

Deficiency is contingent upon insufficient or deficient absorption and storage capacity. This deficiency could be prevented in vegan subjects by consuming dietary supplements that compensate for its level.

The diagnosis is typically determined by analyzing the results of tests that are conducted in response to the onset of symptoms, including:

Anemia; Feelings of muscle fatigue and respiratory insufficiency;
Tingling in the hands and feet; Pallor; Dizziness; Confusion; Difficulties walking

What are the causes and symptoms of excesses?

The cause of a high B12 level is often attributed to a variety of pathologies that are extremely detrimental to our health:

Myeloproliferative disorders; liver diseases;
Solid neoplasms; Kidney failure; Alcoholism

It is crucial to bear in mind that the prevalence of these diseases does not necessarily imply the presence of high B12 levels. Additionally, excess causes a variety of symptoms:

Tremor; Swellings; Excessive nervousness; Rapid heartbeat;

Issues with the kidneys

Many patients who experience these symptoms are uncertain about how to reduce B12 levels when they are so elevated. However, it is crucial to bear in mind that none of these conditions are likely to persist for an extended period, as the majority of the excess is excreted through urine.

What are the primary issues associated with excess?

A daily intake of 2.4 micrograms per adult is recommended by nutritionists. The following adverse effects may occur if we consume a higher quantity of vitamin B12, as our body is unable to effectively eliminate the excess:

Heart failure: The heart may be unable to adequately circulate blood as a result of an excess of B12 in the body, resulting in episodes of heart failure. This is the reason why patients with cardiac conditions must avoid consuming excessive amounts of B12, particularly in the form of injections, unless they are under the close supervision of a physician.

Renal and hepatic failure. Excessive consumption of this type can result in substantial harm to the liver and kidneys.

Clot formation.

An additional adverse consequence of excessive vitamin B12 is that it promotes the formation of blood clots, which can be extremely hazardous due to their obstruction of normal blood flow. Consequently, individuals who have experienced blockages or strokes should also refrain from consuming additional B12.

Visual impairments. Additionally, it is feasible to experience impaired vision as a consequence of an excessive accumulation within the body.

How can the levels be reduced?

Some contraindications may result from an overabundance. Due to this, it is crucial to be aware of how to reduce it by monitoring one’s diet.

It is advisable to eliminate certain animal-derived substances in order to prevent B12 hypervitaminosis, including:

Egg; Milk and derivatives; Meat; Fish

It is crucial to decrease the consumption of legumes, soy, wheat germ, and other plant-based products that contain this.

Physical activity is another critical factor in the correction of B12 levels, as it facilitates its elimination through perspiration. Additionally, it is advised to consume an abundance of water to facilitate its elimination through perspiration.
