Vitamin B12 naturally occurs in some foods and is added to the others. It is also available in the form of dietary supplements and prescription medication for people, who do not eat meat (vegans and vegetarians) or for people with gastrointestinal disorders affecting nutrient absorption from the gut.
Vitamin B12 exists in several forms. As it contains the mineral cobalt, it also has another name – cobalamin. This nutrient plays an integral role in the proper functioning of the nervous system and the production of red blood cells. It is also involved in many metabolic processes occurring in the human body. It primarily affects fatty acid metabolism, amino acid metabolism, and DNA synthesis.
The beneficial effects of vitamin B12 on the central nervous system are numerous. It keeps the nerve cells needed for neurotransmitter signaling healthy and helps in the formation of the myelin sheath, which is a protective covering for the nerve cells. That is why a deficiency of vitamin B12 might deteriorate your cognitive abilities.
The required daily amount of vitamin B12 ideally is 2.4 mcg. For pregnant and lactating females, the recommended daily intakes are 2.6 mcg and 2.8 mcg respectively.
The deficiency of this vitamin in the body is characterized by fatigue, constipation, muscle weakness, megaloblastic anemia, weight loss, and the loss of appetite. #B12 #Novus #IVNutrition
