The Importance and Effects of Vitamin B12 on the Body
Vitamin B12, a vital nutrient for human health, has a diverse range of effects on the body that are still being studied. However, one thing is certain – Vitamin B12 plays a crucial role in maintaining a healthy life.
One of the key functions of Vitamin B12 is its involvement in important bodily processes. It is essential for the formation of red blood cells and DNA. Additionally, Vitamin B12 is crucial for the proper functioning of the nervous system as it helps in the regeneration of nerve cells. A deficiency of this vitamin can lead to symptoms such as fatigue, shortness of breath, and nervousness.
According to the Society for Applied Vitamin Research (GVF), Vitamin B12 is the most complex of all vitamin molecules and belongs to the cobalamin group of compounds, which are known for their distinctive red color. It is involved in various biological processes and is vital for humans.
One important function of Vitamin B12 is its role in breaking down homocysteine in the blood. Homocysteine, an amino acid, can impact blood vessels and increase the risk of heart attack or stroke when present in high concentrations. Vitamin B12, along with folate, helps in the breakdown of homocysteine. Furthermore, Vitamin B12 is also involved in cell division, blood formation, synthesis of DNA, and maintaining the health of nerve cells.
Unlike other water-soluble vitamins, Vitamin B12 can be stored in the body in substantial quantities. Adults have a storage capacity of 2.5 milligrams, compared to the recommended daily requirement of around 4 micrograms, according to the German Nutrition Society. However, a deficiency becomes apparent only after the storage has been depleted for an extended period.
It is important to note that the body cannot produce Vitamin B12 on its own, and therefore, it must be obtained through food. A significant challenge arises for individuals following a vegan diet since Vitamin B12 is primarily found in animal foods. Vegetarians and vegans need to ensure they get enough Vitamin B12, as deficiency is common in this group.
Scientific research has confirmed several effects and benefits of Vitamin B12. According to the European Food Safety Authority, Vitamin B12 contributes to normal energy metabolism, normal function of the nervous system, normal homocysteine metabolism, normal psychological function, normal red blood cell formation, normal immune system function, reduction of tiredness and fatigue, and cell division.
As per the GVF, Vitamin B12 is formed exclusively through microbial synthesis in the digestive tract of animals. Therefore, it is found in fermented products like sauerkraut, albeit in an inactive form. Consequently, individuals following a purely plant-based diet are advised by the German Nutrition Society to supplement their diet with Vitamin B12.
Vitamin B12 supplements can be beneficial for increasing the concentration of the vitamin in the blood, especially for vegans and those with chronic stomach or intestinal diseases. However, supplementation should be done under the guidance of a healthcare professional. It is important to note that long-term intake of high doses of Vitamin B12 may increase the risk of lung cancer, as indicated by a study conducted by the German Cancer Research Center. It is recommended to not exceed 25 micrograms of Vitamin B12 per day through dietary supplements, according to the Federal Institute for Risk Assessment.
In conclusion, Vitamin B12 is an essential nutrient with diverse effects on the body. It is crucial for various bodily functions, including the formation of red blood cells, DNA synthesis, and nerve cell regeneration. For those following a vegan or plant-based diet, it is important to ensure adequate intake of Vitamin B12 through supplementation. As with any dietary changes or supplementation, consulting a healthcare professional is advised to determine the appropriate dosage and minimize potential risks.]
