Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for the body. It cannot be produced by the body in optimal amounts, but must be obtained from food or dietary supplements.
It can only be obtained from meat, and after the age of 50 supplements are needed because the body no longer produces it at all.
“If vitamin B12 does not exist in the body in normal amounts, know that it gives some incredibly dangerous disorders. The nervous system does not develop, tingling, pain, dizziness, delirium appear. People have no more memory, they confuse everything, they forget everything. They have all the neurological and nervous symptoms because the myelin sheath necessary for the nerves to function well is no longer made. Many times, it seems that the lack of vitamin B12 causes irreversible conditions. After 51 years, everyone on this plant no longer has the possibility to have this vitamin in normal amounts, no matter what they eat. Vitamin B12 is only found in products of animal origin, because it is made by some microbes that transform a whole series of substances into this vitamin”, says nutritionist Virgil Stroescu.
He says that it is necessary to analyze vitamin B12 and supplement it in the body.
Vitamin B12 is also necessary in the synthesis of DNA, the body’s genetic material. Vitamin B12 deficiency can lead to growth and development problems. Food sources of vitamin B12 are mainly animal foods such as beef, fish, eggs, milk and dairy products.
People who follow a vegetarian or vegan diet may be more prone to vitamin B12 deficiency.
“Not all plant foods produce B12. There are some who say it has spirulina, brewer’s yeast, pickles, but B12 as such is only found in animal food. That’s why all vegans need to take a B12 supplement. We consume about one microgram of B12 every day. If we take 2 micrograms a day and the year has 365 days, we take about 720 micrograms we need for a year. There are tablets that have 1,000 micrograms or 5,000. So what do we do without B12? When we inject it, it goes directly into the blood, otherwise we need hundreds and thousands of micrograms to have normal amounts in the blood”, adds Virgil Stroescu.
If the analysis shows that we have less than 500 units, we need to supplement.
“If we have, say, 300, we go to a hematologist. We do a calculation and do 7 days one injection per day of 1,000 micrograms, then one per week, then one per month for years. This is the only way they are sure that B12 is normal. All people over 50 must do the analysis and they will be in for a surprise. It costs about 50-70 lei,” she says.
Vitamin B12 plays an important role in many physiological processes: the formation of red blood cells (vitamin B12 is essential for the production of hemoglobin, the protein that carries oxygen through the blood. Vitamin B12 deficiency can lead to megaloblastic anemia, a condition in which red blood cells are large and abnormal, which prevents them from carrying oxygen effectively), the functioning of the nervous system (vitamin B12 is needed to make myelin, a substance that protects and insulates nerves. Vitamin B12 deficiency can lead to nerve damage, which can cause symptoms such as tiredness, numbness, tingling and coordination difficulties)
