Drugstore articles: Vitamin B12 Video Guide

Vitamin B12 is irreplaceable for the body and is generally ingested through food. In certain life situations it may be necessary to take additional vitamin supplements. The substance is responsible for cell division, blood formation and the function of the nervous system. The active ingredient is also contained in many ointments for the treatment of psoriasis and neurodermatitis

Adults should take about 2 micrograms of vitamin B12 per day. Newborns require 0.4 micrograms per day in the first four months. You will receive a sufficient amount through breast milk. However, if the mother has a vegetarian diet, her breast milk may contain too low a dose of vitamin B12. After consultation with the pediatrician, the administration of vitamin B12 can be determined. Disturbances in the absorption of the vitamin can also lead to a too low dose in breast milk. At the age of 4 to 12 months, the requirement is increased to 0.8 micrograms per day. Up to the age of 15, the required quantity increases from 1 microgram to 3 micrograms. Pregnant women and nursing mothers should take in 3.5 to 4 micrograms per day. If this amount cannot be covered by the food, supplementary gifts are necessary. The exact dosage is stated on the package inserts or on the packaging of the food supplements and must be observed in all cases. Overdosing must be avoided. Risks and side effects must be checked by consulting the doctor or pharmacist and by reading the package insert carefully. If there is an increased need for vitamin B12, the underlying causes must be clarified medically. Harmless possibilities are a strong physical strain, for example for professional athletes

An undersupply of vitamin B12 can lead to anaemia, blood count disorders and nerve problems. In many cases you feel a cold feeling in your feet and hands or notice a tingling sensation in your extremities. Feelings of weakness, exhaustion and concentration disorders are also possible. Medically proven overdoses manifest themselves in skin problems and local allergic reactions. They are usually produced by intravenous administration of vitamin B12. An alternative form of administration is the tablet. It is absorbed with sufficient water and the exact instructions must be followed. It can be pure vitamin B12 and carrier substances or you can opt for a combination preparation that contains a balanced mixture of various vitamins and minerals

The US-American George H. Whipple examined the pernicious anaemia, a malignant anaemia in dogs. He discovered in the early 1920s that feeding raw liver could save the lives of animals. Six years later, the two doctors Georg R. Minot and William P. Murphy tried to find the active substances contained in the liver. Together with Whipple, they were awarded the Nobel Prize in Medicine in 1934 for their discoveries. However, the isolation of vitamin B12 proved to be difficult and only succeeded in crystalline form much later. Both an American and a British research team were successful on this point in 1948. The molecular structure of vitamin B12 was investigated in 1955 by biochemist Dorothy C. Hodgkin, who was awarded the Nobel Prize in Chemistry for her work in 1964. In 1972 Robert B. Woodward and Albert Eschenmoser achieved success in the total synthesis of vitamin B12. The motivation for the discovery and research of vitamin B12 was from the beginning to use the substance for the promotion of health and the healing of diseases. Even today, vitamin B12 is considered vital and must be taken in through food or dietary supplements. Whereas in the past it was difficult to isolate the substance, today vitamin B12 is contained in various preparations. They can be solid tablets, effervescent tablets or a powder.
