Vitamin B12 is essential for the functioning of our body. Discover where you can found it and which are its benefits.
Vitamin B12 is a water-soluble vitamin. After the body uses these vitamins, the excess amounts are eliminated in urine. Human body can store vitamin B12 in the liver for years.
Like the other B vitamins, it is important for protein metabolism. It supports the normal function of nervous system and is needed for red blood cell formation and DNA synthesis.
Vitamin B12 occurs naturally in foods of animal origin, such as fish (shellfish), meat (such as organ meats and beef), poultry, eggs, milk, and dairy products.
It is generally not present in plant based foods. Fortified breakfast cereals are an available source of vitamin B12, including some nutritional yeast products.
Vitamin B12 deficiency occurs when the body does not receive or cannot absorb the amount of vitamin the body needs. The daily requirements of vitamin B12 are 2.4 to 4 mcg, in people who eat an omnivorous diet.
Deficiency can cause: anemia, loss of balance, tingling in the arms and legs, and weakness. It commonly occurs in people over 50 years old, who follow a vegetarian or vegan diet, and in people who have digestive conditions such as celiac disease.
