STRENGTH, HEALTH AND ENERGY What is B12 100mcg? Vitamin B12 is a water-soluble vitamin and is one of the most important micronutrients that we get from foods of animal origin. This vitamin participates in a series of processes that participate in maintaining health. Vitamin B12 plays an important role in the process of cell division, contributes to the normal functioning of the nervous system, participates in the metabolism of homocysteine and the creation of energy. Also, this vitamin is of crucial importance for the creation of red blood cells, helps to reduce fatigue and strengthen immunity. Vitamin B12 is absolutely essential for good mental and physical health. Vitamin B12 is the largest and most structurally complex vitamin, and it can only be synthesized by certain probiotic bacterial species. Vitamin B12 participates in the creation of DNA, the genetic material of the cell. Together with other B vitamins, it participates in the formation of red blood cells. It supports brain function (memory and focus), immune system, energy production and metabolism of fats, carbohydrates and proteins. It contributes to the normal work of the cardiovascular system by maintaining normal levels of homocysteine. It is crucial for maintaining the nervous system and preventing damage to myelin sheaths, the insulating material that envelops nerve cells. Children need a constant supply of vitamin B12 for the healthy development of their immune and nervous systems. Absorption of vitamin B12 is a complex process that depends on a number of factors. A lack of any of the factors can lead to a deficiency of this vitamin. This complex process of absorption is primarily dependent on adequate synthesis and secretion of the intrinsic factor by cells of the stomach, but also a number of other locally present factors: adequate composition and acidity of gastric juice, adequate composition of pancreatic juice, intactness of the intestinal mucosa as well as the appropriate microflora. Vitamin B12 deficiency is most often caused by low intake, but it can also be caused by malabsorption, certain intestinal disorders, low concentration of binding proteins, and the use of certain medications. Vitamin B12 has almost no plant sources, so vegetarians are more likely to suffer from its deficiency. Children are at greater risk of the deficiency if they are born to mothers who do not consume meat. The elderly and all those who need to improve memory, concentration and mental clarity need additional intake of vitamin B12. Vitamin B12 100mcg sublingual tablets are recommended for: people with megaloblastic anemia during total or subtotal gastrectomy people with a deficiency of the inducing factor alcoholism vegans and vegetarians people who use ampullary form of B12. Due to various dietary, physiological and lifestyle factors, vitamin B12 deficiency is a common and frequent problem that can lead to: anemia, mental fogginess, poor memory and concentration, fatigue, irritation, feeling apathetic and lack of motivation, mood swings, weakness in muscles or sleep problems. A deficiency of this vitamin can also contribute to weakened immunity and repeated infections, damage to the myelin sheaths of nerve cells, birth defects, age-related hearing loss, or increased homocysteine levels and an increased risk of cardiovascular problems.
